Vibrations, imprecise guides on separating safety components, high demands on robustness in harsh environments – magnetic safety switches of the RE series from SICK solve requirements that see other switches fail.

Packaging machines, panel separators, printing and assembly equipment are only a few among many types of devices whose access areas are often protected by hoods, hatches, or doors. The magnetic safety switches of the RE series constitute the optimum solution for safe monitoring of these protective components, since they master tolerances in door guides and machine openings, withstand the harsh conditions involved in external cleaning of facilities, and are free from wear and maintenance. In this way, they offer not only safety up to performance level “e” but at the same time ensure a high degree of plant availability and process safety. The product portfolio includes sensors optionally with one N/O contact and one N/C contact in cubic or metric design, with two N/C contacts, or one variant with three N/C contacts and an additional status LED display. All of the sensors manage without an individual evaluation unit, but instead they can be connected flexibly to any of the appropriate safety switching devices and safety controllers.

In terms of integration into safety engineering, the safe switching devices, controllers, and network solutions from SICK provide added value in the system.
