Belt Conveyor – Pull Rope Switch HEN 211

Resource Industry Solutions Pull Rope Emergency Stop Switch Type HEN 211


Kiepe pull-rope emergency stop switches type HEN 211 are used in accordance with the requirements of EN 620 as well as BGI 710 and in conformity with DIN EN ISO 13850 as emergency stop devices as supplementary safety measures on conveyor belt systems. The pull rope is symmetrically tensioned on both sides of the red release lever. The devices are suitable for outdoor use and applications where the ambient temperature varies considerably.

With the pull-rope system functionally aligned, the emergency stop signal can be triggered over a distance of up to about 100 m for each switch.

Kiepe pull-rope emergency stop switch types HEN 211 comply with Machinery Directive 2006/42/EC and meet the requirements in the safety objectives of Low Voltage Directive 2006/95/EC.

The HEN 211 aluminum housing is equipped with two NC-and one NO-Contact. The NO-Contact is connected to a bus modul, which watches and signalizes the switching status (in/off) economically over long distances.

Pull rope emergency stop switches Type HEN 211 must only be used in control electrical circuits. Taking into consideration the safety data and maintenance recommendations, the pull-rope emergency stop switch type HEN 211 can be used in safety circuits in accordance with DIN EN ISO 13849 up to Performance Level e (PLe).


The pull-rope emergency stop switch is actuated by a pull rope 1 connected on both sides of the red release lever. The contacts are actuated by a spring supported cam disc (snap action function). At the same time, two NC contacts and one NO contact are actuated simultanously.

The emergency stop signal is performed with positive-making normally closed (NC) contacts in accordance with the closed circuit principle. The NO-contact activates the bus modul 101.

The bus module 101 must be programmed before installation.

After the emergency stop function is triggered, the switching mechanism is locked in the shut-off position “0”. When the blue reset lever is actuated in switch position “1”, the switching contacts are reactivated and the conveyor belt is prepared for being turned back on again.

Resetting the pull-rope emergency stop switch must not cause the conveyor system to start up.
