BERNSTEIN safety technology: Selection of safety switches and sensors

Safety switch with guard lockingReliable door interlock for movable guards

When machines have to come to a standstill, safety must not be compromised: Safety switches with guard locking ensure that doors, bonnets and flaps remain reliably locked - and only open again when it is really safe to do so. In industrial automation, in plant engineering or when safeguarding safety gates, they make a decisive contribution to protecting people and machines.

With the SLK and SLC series, BERNSTEIN offers two solutions that are characterised by their compact design, high reliability and simple integration. They can be used flexibly and are ideal for industrial applications with clear safety requirements.


Standstill that protectsReliable guard locking solutions for movable guards

Whether in series production, robotic systems or complex special machines - safety switches with guard locking make an important contribution wherever dynamic processes need to be safely shielded.

They have proven themselves in a wide range of industries and system concepts - from metal processing and packaging technology to the food industry.

The compact design, simple integration and reliable interlocking make BERNSTEIN solenoid interlocks a flexible solution for a wide range of applications.

This means that guards can be specifically secured without restricting design freedom.

The right safety switch with guard locking for every doorTwo variants - one principle: safe guard locking

The SLK and SLC safety switch with guard locking are based on the same operating principle, but are optimised for different operating conditions. While the SLK has a particularly compact design and is suitable for tight installation situations, the SLC offers a robust alternative for applications with increased mechanical requirements. Both variants work with either spring or magnetic locking and have a locking force of 1500N.
