General purpose photoelectric sensors are suitable for many presence sensing applications. Using infrared or visible red light technology, these sensors are available in diffuse, diffuse with background suppression, retroreflective and through-beam sensing styles. AC and DC-powered models offer a range of sensing distances and connection options, in tubular or rectangular body styles.
General Purpose Photoelectric Sensors
Category Selection
High-quality, lower-cost alternatives to other suppliers' industrial photoelectric sensors
Photoelectric sensors can detect a wide variety of materials and can have extended sensing ranges, depending on the sensing technology used.
Diffuse sensors bounces emitted light directly off an object and back to the receiver in the same housing.
Retroreflective sensors bounce light off a fixed reflector and objects are detected when they break the beam.
A through-beam photoelectric sensor uses a configuration where the emitter and receiver are in different housings and detect presence when the beam is broken. Through-beam sensors provide the longest operating distances since the emitter shines light directly at the receiver.
General purpose photoelectric sensors are available in basic, standard and harsh duty ratings, and a range of tubular and rectangular form factors and sizes, including the popular 50 x 50mm industry standard. A variety of housing material options are available.
