Safe locking devices and switches

Open is off

For doors, flaps and covers that must remain closed during the operation of machines, Safety Switches for position monitoring and for the protection of personnel and systems are required. They are predestined for guarding machines and systems in which process or production interruptions are, in principle, possible or may be necessary. In addition to standard designs for universal use, Safety Hinge Switches and Safety Position Switches are available as alternatives to hinge switches on flaps.

The door stays closed!

Safety Locking Devices keep protective doors securely locked and thereby prevent the inadmissible access of people until the guarded machine no longer poses a danger. Not until there is no longer a danger to the machine or to the workers is access released by an electric signal. The Safety Locking Devices thereby make an important contribution to personnel protection and machine protection. With their robust design, all Leuze electronic Safety Switches and Locking Devices are designed for rough industrial applications.

For stopping in emergencies, EN ISO 12100‑1 stipulates protective devices and supplementary measures such as E‑Stop buttons or emergency rope switches. For this purpose, Leuze electronic offers solutions that were developed and optimized with respect to safety and ergonomics acc. to EN IEC 60204-1, EN 60547-5-1/5 and EN ISO 13850. These series are used exclusively for outputting the E‑Stop signal.

The magnetically coded safety system is predestined for use under critical environmental conditions, i.e. wherever stress due to dust and humidity is high. Easy start-up, compact housing and extremely low costs characterize this robust series.

Due to the intelligent and extremely robust technology, safety transponders are well-suited for applications in which a very high level of safety up to category 4 or Performance Level PL e and the highest protection against manipulation are necessary – even with series connections of up to 32 transponders. Their high-strength plastic housing offers reliable protection against contamination and humidity in rough environmental conditions. The detailed diagnostics function reduces start-up and testing time.
