Sensor amplifiers use application specific circuitry to condition a sensor's raw output signal into a usable form through amplification and conversion. Output types include analog voltage or current, digital, NPN or PNP transistor, linear and relay contact(s). Common mounting types include bracket, cable, chassis, DIN rail, board surface, and through-hole.
Encoders are devices that are designed to translate motion or position changes into electrical signals. By tracking the motion either optically, mechanically or by changing magnetic fields, encoders can output electrical signals either in code such as by binary, octal, hexadecimal or grey code or by changing output signals such as frequency or differential voltage. With a range of supply voltages, mounting types, output resolution per revolution and actuators, encoders can fill a range of applications.
Float, Level Sensors
Products within this category are used to measure or detect a fluid or material level within a container, commonly through the use of a buoyant element containing or connected to a switch of some type, but in other cases through the use of ultrasonic, optical, or other techniques. Outputs produced by these devices may be variable to allow a quantitative measurement of fluid/material level, or a simple binary indication of whether or not the level is in excess of some fixed value.
Products within this family are used to measure or detect the flow of a fluid such as water or air. The simpler products provide a binary indication of whether or not the flow rate exceeds some defined value, whereas the more complex products are capable of providing a variable output from which the amount of fluid flow can be determined as a mass or volume-per-time quantity. Device performance in either case is quite strongly related to the properties of the working fluid, and media compatibility issues are also a matter of noteworthy concern for device selection and application.
IrDA Transceiver Modules
Infrared transceivers incorporate an infrared emitter, a photodiode and control circuitry in a single device package for use in data transmission at rates as high as 16 megabits per second. Modules are available as Serial (SIR), Mid (MIR) and Far (FIR) variations with side or top view options. The Infrared Data Association (IrDa) provides protocol specifications for wireless data communication such as IrDA 1.x and IrPHY 1.x for use with infrared transceivers.
Magnetic Sensors - Switches (Solid State)
Products in this family use solid-state technology for detecting the presence of a magnetic field in excess of some specific magnitude and/or sign, and provide a two-state output indicating the presence or absence of such a field. They are distinct from reed switches, which provide a similar function through the use of moving mechanical parts, as well as from linear or compass-type solid-state devices which provide a variable output indicative of the strength and/or orientation of an applied magnetic field.
Motion Sensors - Accelerometers
Accelerometers are designed to detect and respond to changes in acceleration like movement or vibrations. The Accelerometer types are Analog or Digital in the X, Y, or Z axis with an acceleration range of ±0.5 g to ±2000 g and a sensitivity of 1 to 500 k (LSB/g) with output types of Analog Voltage, Bluetooth, Digital, DSI, IEPE, I2C, PCM, PWM, RF, and SPI.
Motion Sensors - Optical
Products in the optical motion sensor family use light (usually infrared) to detect object movement. Passive infrared types detect changes in the amount of infrared light falling on the sensor, such as caused by a warm body passing through their field of view, whereas area reflective types emit light and detect changes in the amount that is reflected by nearby objects. Products such as light curtains for machine safety which detect object presence rather motion are not included.
Motion Sensors - Tilt Switches
Products in the tilt switch family are designed to provide a binary (two-state) indication of whether or not their orientation with respect to gravity is in excess of some specified angular value. Commonly, though not exclusively, based on a passive mechanism of action such as the motion of a conductive element under the influence of gravity, such sensors can operate without need of an external power source in applications where inclination threshold detection is sufficient, as contrasted with inclination magnitude measurement.
Optical Sensors - Ambient Light, IR, UV Sensors
Ambient light, IR and Ultraviolet optical sensors convert their respective light and/or heat inputs into an analog or digital output and are available in a wide variety of surface mount and through hole package types. The wavelength for these sensors range from 290nm to 4000K.
Optical Sensors - Image Sensors, Camera
Products in the image sensor and camera family are component or module-level devices used to electronically capture visual information in the visible and/or infrared spectrums. Consisting of an array of photosensitive elements connected to a shared control and interface mechanism, available products include those adapted to common still image and video capture as well as more specialized applications such as thermal and spatial imaging.
Optical Sensors - Photo Detectors - Remote Receiver
Products in the remote receiver photodetector family integrate a light sensitive element such as a photodiode with filtering and amplification functions, and are used as receivers for information transmitted via modulated infrared light. Most commonly found in devices such as televisions and other consumer products that are manipulated through the use of handheld remote controls, available devices vary in the extent of the filtering and signal processing they provide, resulting in various degrees of sensitivity and immunity to interfering ambient light.
Optical Sensors - Photodiodes
Products in the photodiode family are used for detection and measurement of light. Based on the interaction of light with a semiconductor junction similar to that found in rectifier diodes, devices adapted for a wide range of purposes are available. Some are adapted for sensitivity over narrow wavelength ranges, others for sensitivity over a wide range. Some are suitable for detection of high-speed signals such as encountered in fiber optic communications, others for detection of extremely low levels of light (even individual photons) with applications ranging from medical imaging to distance measurement.
Optical Sensors - Photoelectric, Industrial
Industrial photoelectric sensors transmit fixed wavelengths of light to determine the distance, absence, or presence of an object by ignoring ambient light and detecting changes in the transmitted light returning to its receiver. The sensors are housed in rugged cases ideal for industrial environments. Sensing methods include cross-beam, through-beam, diffused, reflective, retroreflective, transmissive, proximity, distance and line focus. The sensors are further differentiated by light source color and wavelength, sensing distance, ingress protection and output configuration.
Optical Sensors - Photointerrupters - Slot Type - Logic Output
Products in the logic output, slot type photointerrupter family integrate a light source and a matching photodetector in an opposed-facing orientation, together with supporting circuitry needed to make a binary (two-state) determination of whether or not an opaque object or material is present in the space between the emitter and receiver. They differ from transistor output devices of the same name by virtue of this additional receive-side processing, which simplifies application at some expense of application flexibility.
Optical Sensors - Photointerrupters - Slot Type - Transistor Output
Slot type photointerrupters with transistor output are optical sensor modules that utilize a built-in infrared light source and a photodiode separated by an air gap (slot). When an actuator, liquid or other detection object blocks the light source, an output transistor is turned on or off which toggles the applied voltage. Mounting options include chassis, snap-in, surface, free-hanging, and through-hole.
Optical Sensors - Phototransistors
Products in the phototransistor family are discrete light sensitive components which behave in similar fashion to a bipolar transistor, but use incident light instead of an electrical current applied through a device terminal to cause the device to conduct. Compared to photodiodes, phototransistors generally produce a much larger output current for the same intensity of incident light, though are slower to respond to changes in light intensity. These differences result in phototransistors being simpler to apply, but less useful for high speed operation.
Optical Sensors - Reflective - Analog Output
Products in the analog output reflective optical sensor family incorporate an optical emitter and light sensitive element (typically a phototransistor) mounted adjacent to each other and facing the same direction, such that light from the emitter that is reflected by an object in the sensor's field of view can be detected by the sensing element within the device. Analog output sensors of this type deliver the signal produced by the photosensor directly with minimal processing, requiring the user to provide their own interpretive mechanism to determine object detection.
Optical Sensors - Reflective - Logic Output
Products in the logic output reflective optical sensor family incorporate an optical emitter and light sensitive element (typically a phototransistor) mounted adjacent to each other and facing the same direction, such that light from the emitter that is reflected by an object in the sensor's field of view can be detected by the sensing element within the device. Logic output sensors of this type produce a binary (two-state) signal on the basis of whether or not the optical signal received by the photosensor exceeds some specified threshold value.
Particle, Dust Sensors
Products in the dust sensor family are modular devices used to measure the amount of suspended particulate matter in the ambient air. Used for health and safety applications, clean room monitoring, and similar purposes, the available devices are varied in their sensitivity characteristics, particle classification capabilities, maintenance requirements, and similar details of operation.
Position Sensors - Angle, Linear Position Measuring
Angle and linear position measuring sensors use capacitive, Hall effect, inductive, LVDT, LVIT, magnetoresistive, optical or resistive technology to determine the position of the sensor's actuator relative to a reference point. Angle position sensors are differentiated by their electrical or mechanical range in either a limited or continuous rotation range. Linear position sensors are differentiated by ranges from 0 up to 400 inches. Other considerations include actuator type, output type and signal, mounting type and percent linearity.

The pressure types are Absolute, Compound, Differential, Gauge, Sealed Gauge, Switch, Vacuum, and Vented Gauge with operating pressures from -100PSI (-689.48kPa) to 20000PSI (137895.15kPa).
Proximity Sensors are designed to detect and respond to movement outside of the component and within the range of the sensor (0” (0 mm) to 50’ (15.2 m)). The sensor types include capacitive, inductive, infrared, light, and ultrasonic with output types of analog current, voltage, configurable, I2C, NC, NO, NPN, 2-wire, 3-wire, 4-wire, 5-wire, PNP, push-pull, relay, requires amplifier, and SCR.
Sensor Interface - Junction Blocks
Junction blocks for sensor interface applications are interconnect devices used to combine signals from multiple sensors or actuators having individual cabling requirements into a shared cabling system that is better suited for carrying signals over long distances by virtue of eliminating unnecessary conductors and electrical insulation material.

The sensor types are analog local/remote/infrared, analog-digital, local/remote, digital local/remote/infrared, or internal, with a sensing temperature range of -55°C to 200°C.
Temperature Sensors - NTC Thermistors
NTC Thermistors, or Negative Temperature Coefficient Thermistors, are devices that change resistance in response to changes in temperature. With negative coefficient parts, their resistance decreases as their temperature increases. They are typically defined with variables such as the parts base resistance value at a set temperature, usually 25°C, and B values, the performance curve of temperature vs. resistance calibrated between two fixed points.
Ultrasonic Receivers, Transmitters
Ultrasonic Receivers and Transmitters are designed to detect and transmit high frequency sound waves, respectively. They are characterized by frequency, rated voltage, and beam angle. Their typical operating frequency range are 50Hz, 10kHz to 65kHz, 20kHz, 25kHz, 28kHz, 38kHz to 42kHz, 40kHz, 42kHz, 49.5kHz, 58kHz, 60kHz, 300kHz, 1MHz, 2.45mHz, and 168MHz.
