Widely Applications: ATO Photoelectric sensors have been used as position detection, liquid level control, product counting, width discrimination, speed detection, fixed length cutting, holes recognition, signal delay, automatic door sensing, color scale detection, punching and cutting Machine and security and many other areas. In addition, using the stealthiness of infrared, photoelectric sensors also can be used as a burglar alarm in banks, warehouses, shops, and offices.
Q: Does the photoelectric switch sensor have to be connected to a PLC to work properly?
A: Our photoelectric sensor can be connected to a relay to work, not necessarily a PLC.
Q: Does the sensor miss an object from time to time during detection?
A: Generally the photoelectric switch would not miss an object during detection, if it does, you can check to see if there are interfering beams, or objects that overlap and pass through.
