Photoelectric sensor is a generic name for sensors which detect an object by using light. The optical signal transmitted from the emitting part of the sensor is modified by being reflected, transmitted, absorbed, etc., by the sensing object and is then detected by the receiving part of the sensor to generate a corresponding output signal. Further, it can also be a sensor which detects light radiated from the sensing object to generate an output signal.
Fiber sensors and laser sensors are also one type of photoelectric sensor.

Most of the photoelectric sensors emit a beam which is pulse-modulated. |
The high-speed fiber sensor FX2-A3R and the micro photoelectric sensor PM-64/24/44/54 series use an unmodulated beam. |
Non-contact detectionDetects an object without contact. Long sensing rangeThe thru-beam type with a maximum sensing range of 50 m 164.042 ft (RX-M50), and the diffuse reflective type with a maximum sensing range of 5 m 16.404 ft (PX-26) are available. The long sensing range make the sensors suitable for a variety of applications. Various objects detectableThe sensors can detect objects of any material provided they affect the optical beam. Short response timeThe use of an optical beam for detection and complete electronic circuitry makes the sensors respond so quickly that they can be easily used on a high-speed production line. |
Color identificationThis is a special feature of photoelectric sensors, which use light for detection. High accuracy detectionAdvanced optical system and electronic circuit technology have achieved a sensing accuracy of up to 20 μm 0.787 mil (SH-82R).
