BERNSTEIN AG's range of safety switches and sensors includes a large number of different products that all have the same task: The safe detection of an open door, flap or bonnet.
In addition to secure door monitoring, the products also have other features that offer added value.
For example, the safety hinge switch, type SHS3, which combines hinge and safety switch in just one product. Or the non-contact safety sensor SRF, which provides a wide range of application and sensor information thanks to its diagnostic function.
Non-contact, RFID-coded safety sensors with intelligent diagnostic function for monitoring movable guards.
Coordinated coded encoder units (magnetic switch and magnet). The contacts are evaluated and monitored by the magnet monitoring systems.
Safety switchesHinged applications
The SHS safety switches combine hinge and safety switch in only one product. The safety guard is monitored directly in the safety hinge switch.
Safety switchesSeparate actuator
Safety switches with separate actuator are positive opening position switches for safeguarding machines and systems of any complexity.
Safety switcheswith guard locking
Safety switches with guard locking function ensure that safety gates, safety doors and other protective guards remain closed for as long as a hazardous situation exists.
Safety switches and sensors to protect people and machinery
»For us at BERNSTEIN, good safety technology is characterised primarily by the fact that it reliably prevents damage from people and machines. This includes that the individual components are securely protected from manipulation attempts. Modern safety technology also fulfils the requirement of networking components with each other. Diagnostic functions are the icing on the cake. In this way, safety technology components generate real added value.« – Nicole Bernstein | Board member
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 a component of the risk assessment, the risk analysis identifies, among other things, hazards emanating from the machine and then assesses their risks, taking into account various aspects.
A necessary mitigation of the risk can be achieved either by eliminating the hazard or by mitigating the aspects. In practice, this is usually an enclosure of the hazardous area in which access must exist for various reasons (cleaning, maintenance, work process). This access is provided by a movable guard (usually a door, bonnet or flap), but it must be locked.
Depending on the specific application, either a safety switch/sensor or guard locking must be used. We will be happy to help you select the right products, specially matched to your application requirements.
Safety switches with separate actuator are positive opening position switches. The switching element and actuator are separated by design.
On actuation, the switching element and actuator are brought together or separated. The positive opening NC contact is always open when the actuator is withdrawn.
