WZF2-EX
with long actuation travel, EX-version
The safety switch WZF2-EX with separate actuator is intended for the use in explosion endangered areas. It is used to control the close position of lift doors and protective enclosures and as switch for locking mechanism at automatic doors. The actuator is mounted at the door leaf resp. at the locking mechanism. When pulling the actuator out of the switch a forced opening of the contact is made.
