BERNSTEIN safety technology: Selection of safety switches and sensors

Safety switches and sensors from BERNSTEINSecure, lock, monitor. For smooth processes and maximum protection.

They lock flaps, monitor hoods, keep safety doors closed – and ensure that only safe operations are carried out. Safety switches and sensors from BERNSTEIN secure access to machines and systems – precisely, reliably and accurately.

Whether mechanical or electronic, with interlocking or contactless: our switches intervene when it matters – and stay out of the way when everything is fine.
For smooth processes and safety that thinks for itself.


What is a safety switch?Reliable guardians – designed for emergencies

Whenever machines are in motion, control is required – especially at doors, flaps and hoods.
Safety switches perform precisely this task: they check whether an access point is closed – and only release the process when everything is secure.

Unlike conventional switches and sensors, they are certified machine safety components – developed to protect both people and technology.

Whether with interlocking, for example for trailing saw blades, inductive for contactless detection or robust as a mechanical position switch:
The right solution depends on the location of use – but one thing remains the same: the safety promise.

Safety switches for every challengeTechnology that adapts to your processes

Safety switches are available in many designs - but not all of them are suitable for every machine. Different risks, motion sequences and environmental conditions require different technologies.

That's why BERNSTEIN offers a wide range of safety switches that are precisely tailored to your application: mechanical, electronic, non-contact or with guard locking.
For protection that not only works - but also fits your machine perfectly.

According to the Machinery Directive, the manufacturer of a machine must ensure that a risk assessment of his machine or system is carried out, for example to determine the safety requirements applicable to the machine.

As part of the risk assessment, hazards emanating from the machine are identified in the risk analysis and their risks are then assessed, taking various aspects into account.

A necessary reduction of the risk can be achieved either by eliminating the hazard or by reducing the aspects. In practice, this usually involves enclosing the danger zone. However, for various reasons (cleaning, maintenance, work process) there must be access to this area.

This access is made possible by a movable guard (usually a door, hood or flap), which must be interlocked. This guard is usually monitored by a safety switch or sensor.

A safety switch or safety sensor monitors the movable guards of a machine or system. They ensure that users cannot open them if a dangerous situation exists. This is because there may still be a risk even if the machine has already been stopped.

A classic example of this is overrunning saw blades. It is imperative that the operator is denied access until the dangerous movement has come to a complete stop.
