Dong Heng E3JK-DS30M1 photoelectric switch diffusion type AC-DC square photoelectric switch

Photoelectric switches is a kind of sensor, transmitter between the receiver and the light intensity changes into currents of change for the purpose of detection. Because of the photoelectric switch and input circuit is electrically isolated output circuit (that is, edge must), so it can be used on many occasions.

Photoelectric switches have been detected by crops, liquid level control, product count and width distinguish speed, cut-to-length and hole recognition, signal delay, automatic door sensors, color detection, punching and shearing machine and the safety protection and many other areas. Furthermore, the use of infra-red stealth, also in the banks, warehouses, shops, offices and other occasions as a security guard.
