Safety switches

KRONENBERG safety switches are used as water-protected door contacts in the lift industry and millions of times to control the protective enclosures at machines.

Overview

WZA

WZA

Safety switch with clear cover

The water-protected safety switch with separate actuator and clear cover WZA is a safety switch with forced actuation and is used to control the close position of lift doors and protective enclosures. It can be actuated from any direction and allows small swiveling radii with the infinitely variable revolving drive head. The actuator is mounted at the door leaf. A forced opening of the contact is made when pulling the actuator out of the switch.

WZ

Safety switch in especially robust design

The water-protected safety switch WZ with separate actuator is a safety switch with forced actuation and is used to control the close position of lift doors. It is very robust and therefore particularly suitable for lift doors. The actuator is mounted at the door leaf. When pulling the actuator out of the switch a forced opening of the contact is made.

WZF

Safety switch in especially robust design

The water-protected safety switch WZF with separate actuator is a safety switch with forced actuation. It is very robust and has a long actuating travel. Thus an unwanted shutdown of the machine by vibration of the protective device is avoided. When pulling the actuator out of the switch a forced opening of the contact is made. Compared to the WZ a higher protection against manipulation is ensured by multiple coding.

WZF2

WZF2

Safety switch in especially robust design

The water-protected safety switch WZF2 with separate actuator is a safety switch with forced actuation and equipped with two contacts. It is very robust and has a long actuating travel. Thus an unwanted shutdown of the machine by vibration of the protective device is avoided. When pulling the actuator out of the switch a forced opening of the contact is made.

WZK

Safety switch in compact design

The small water-protected safety switch WZK with separate actuator is a safety switch with forced actuation and is equipped with maximum three contacts. The switch is especially small and therefore suited for reduced space conditions. The actuator is mounted at the door leaf. When pulling the actuator out of the switch a forced opening of the contact is made. The cable is already connected to the switch and included in the scope of delivery.

WZV2

WZV2

Safety switch with electromagnetic unlocking

The water protected safety switch WZV 2 with separate actuator is a safety switch with forced actuation and equipped with a monitored locking mechanism. The actuator is mounted at the door leaf. A locking bolt engaging into the actuator prevents the door from opening. By energizing the integrated electromagnet the locking bolt is pulled out of the actuator and the door can be opened.

WZF2-EX

WZF2-EX

Safety switch 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.
