Safety Switch type STA

The robust metal safety switch STA is dimension-compatible with the proven EUCHNER safety switches TP and STP in plastic housings. Due to its die-cast aluminum housing and its high degree of protection IP 67, the switch can withstand even extreme ambient conditions. Like the switches TP and STP, the safety switch STA also offers a guard locking and a guard locking monitoring. A great variety of switching elements is available. The contacts can switch a minimum current of 1 mA. Therefore the safety switch STA is suitable for use in safe control systems.
