2017-12-14 12:00:43

Friction screw press photoelectric is a combination of photoelectric switch and mechanical devices. It is in the die set before a variety of light-emitting, forming a beam and close the front of the operator, up and down the danger zone at the mold. When the operator's hand stays or misses the area, the light beam is obstructed and the signal is sent out. After amplification, the relay is operated by the control circuit, and finally the slider is automatically stopped or can not be descended to ensure the safety of the operator.
Photoelectric protection device according to different light sources can be divided into infrared photoelectric protection device and white burning photoelectric protection device.
