The two-hand touch safety button (TSB1) is designed to be part of the machine's safety-related control system. The touch safety button controls the operation or stop of the actuator by means of the output of a safety-related sensor, providing the operator with a protective device to prevent reaching the danger zone in a dangerous situation.
The TSB1 self-test optical touch button is a touch optoelectronic device designed to replace capacitive touch switches and mechanical buttons. When the finger is placed on the "touch area" (groove) of the switch, the infrared-sensing beam of the button is blocked, and the output is activated.
