Bernstein - 601-8169-060 SAFETY POSITION INTERLOCK SWITCH, 4NC SLOW BREAK CONTACTS, 250V, SPRING FORCE LOCK, 27N, 3XM20 CABLE ENTRIES

Safety Position Interlock Switch, 4NC, Spring force Lock

SLK safety position interlock switch with spring force locking action. The separate actuator is connected form fit with the safety guard. It transfers the locking force to the safety guard and monitors its position.

Thanks to its triple coding, the actuator ensures a high degree of antitamper security. The interlock facility in association with the SLK safety position switches is integrated in the switch enclosure. To lock the actuator in connection with a switching mechanism, the required interlock is achieved by means of a spring mechanism.

Safety position switches with interlock function ensure that safety gates, safety doors and other protective guards remain closed for as long as a hazardous situation exists.

Ideal for use in production processes, safety position switches have a range of tasks including - enabling the machine when the safety guard is closed and interlocked, disabling when open, and position monitoring. The SLK safety switch can be actuated in a horizontal and vertical direction.

The SLK is electrically connected safely and reliably via spring loaded terminals were wires with ferrules can be inserted without the need for tools. The connection compartment is separate from the functional parts contributing to secure and reliable connections and conforms to IP67.
