A solution designed for machine builders who consider human safety as one of their highest priorities has been introduced by EAO. The self-monitoring Series 04 Failsafe Emergency-Stop Switching Element detects if the stop switch actuator becomes disconnected by accidental damage, negligent assembly or misuse. If there’s any defect, the failsafe contact opens and the machinery will behave like in a normal emergency shutdown routine.

According to the company, the device will fit any Series 04 emergency-stop or stop switch and is easily retrofitted. Three types of connection are possible: push-in terminals (PIT) with cage clamps, or screw and plug-in terminals. The product offers a mechanical life of at least 50,000 operations.
