3.Working principle

The protector consists of light curtain, signal cables, controller and control cables.The light curtain can form infrard light curtain, detect the signal of passing or intercepting, and send the signal to control box that also supplies power to the light curtain.The control box processes the signal and outputs the closed or opened signal used safety relay, and then connects the control trip circuit of the press by control cable or other protective equipment to protect the worker.
