Through beam photoelectric sensor consists of a light projector and a light receiver, both of which are separated in structure. The supply voltage is DC 12V-24V or AC 110V-220V. Infrared photoelectric sensor can distinguish the opaque reflective object, with long effective detection distance 5/15/50m, less susceptible to interference, long life, and high reliability.
Diffuse reflective photoelectric sensor consists of light projector and light receiver in one, can distinguish transparent or opaque reflective object. The supply voltage is DC 12V-24V (6-36V) or AC 110V-220V (90-250V). Infrared photoelectric sensor can be compensated for longer distance with sensitivity controller, less susceptible to interference, fast reaction, long life, high resolution and high reliability.
Retro-reflective photoelectric sensor consists of light projector and light receiver in one, has long effective distance range with the help of reflective board. The supply voltage is DC 12V-24V (6-36V) or AC 110V-220V (90-250V). Infrared photoelectric sensor can distinguish the opaque reflective object, with less susceptible to interference, fast reaction, long life, high resolution and high reliability.
Slot-type photoelectric sensor is also known as U-type photoelectric sensor. It's a type of through beam photoelectric sensor and easier to align through beam. Slot type photoelectric sensor can distinguish opaque objects, with power supply DC 12V-24V (6-36V), small installation space, reverse power protection.
Photoelectric sensors & photoelectric switches are composed of a light projector and a light receiver. The light projector converts the input current into an optical signal and emits infrared light. Since the detection object blocks or reflects the light beam, the light received by the light receiver will have changes, thereby photoelectric sensor can detect the object existing or not. The detection object is not only metal, but also any transparent or opaque object that can reflects light or blocks light, such as glass, rubber, wood, liquid, gas, etc. Because it is a non-contact detection, photoelectric sensors won't damage the detection objects, and be affected by them.
