Safety switch STA

Description

The robust metal safety switch STA is physically compatible with the proven EUCHNER safety switches TP and STP in the plastic housing. Due to its die-cast aluminum housing and the high degree of protection, IP67, the switch can withstand even extreme ambient conditions. Like the switches TP and STP, the safety switch STA also has guard locking and guard lock monitoring. A large selection of switching elements is available. The switching contacts switch a minimum current of 1 mA. The safety switch STA is therefore also suitable for use in safe control systems.
