Safety limit switches

A safety switch is more than just a simple switch. It is a protective mechanism designed to save lives and prevent accidents. Whether you are aware of it or not, the special position switches (safety limit switches / safety position switches) play a crucial role in our daily lives and in every industry. Rapidly advancing automation means that more and more workpieces and machines are in motion without having to be controlled manually.

Nevertheless, it can always happen that people have to work on automation systems, for example for maintenance and repair, or enter areas where machines and devices work autonomously. If a person opens the safety door to such an area, or a protective bonnet or cover on a machine, whether due to an emergency or for routine maintenance and operation, the machines must be stopped reliably, safely and accurately. By the way, this does not only work with entire plants and machines. With the help of modern magnetic sensors, the positions of individual moving and potentially dangerous machine parts are also detected and, if necessary, stopped as soon as they have reached an individually defined end position. The signal can be transmitted in different ways, i.e. electrically, hydraulically, mechanically or pneumatically. With our safety limit switches, we rely on electromagnetic transmission.

And that’s not all. Likewise, limit switches can be used to control and monitor safety doors, on the one hand to prevent unauthorised access, for example with the help of RFID coding, and on the other hand to reliably measure when a safety door has been opened, for example by monitoring the position of a door handle to stop the machines in the safety area at the same moment.

We supply all components for the safe, simple and low-maintenance installation of safety limit switches. From individual sensors and safety hinges, to special door handles, to entire switches, pull-wire switches and magnetic switches with a separate trigger.
