In the "Safe Switching and Monitoring" section, you will find an extraordinary large programme of safety-related switchgears for the position monitoring of guard doors and the non-contact protection of hazardous zones and danger points, as well as safety switching appliances for special applications.

Safe signal processing

In the "Safe Signal Processing" section, you will find safety relay modules for various safety technology applications (e.g. for emergency stop and guard door monitoring) as well as centralised programmable safety controllers and decentralised field bus systems, e.g. a modular concept for safety functions control on small machines.

Automation technology

In the "Automation Technology" section, you will find switching appliances for the mechanical position detection in various fields of application as well as (safety) sensors with different operating principles; this section furthermore includes a comprehensive programme of command and signalling devices.

Devices for Ex Zones

The "Ex Switchgear" includes switchgears, which can be used - in accordance with the harmonised standards - in areas with potentially explosive atmospheres due to the presence of gas and dust, e.g. position switches, safety switches and safety sensors with non-contact operating principle.

Lift switchgear

In the "Lift Switchgears" section, you will find lift switchgears for various applications in the shaft pit, the lift car and the machine room: floor and fine-adjustment switches, positive-break door contacts, position switches, magnetic reed switches, remote alarm systems as well as the USP ultrasonic elevator positioning system.
