Always reliable switching and controlling

Switching and Control

Semiconductor contactors have proven themselves in industrial applications everywhere high switching frequencies or high switching cycles are required. With their long service lives and wear-free switching, they handle switching and controlling tasks in specific applications in a highly economical manner.

 

Safety technology is becoming more and more important in machine and equipment construction. Safety modules or even safety controllers are being used everywhere. Despite the increasing use of semiconductors, electromechanical relays remain an important component of such systems. The have the task of switching loads and galvanically separating electrical circuits. Classical applications, particularly for relays with mechanical force-guided contacts, are in the monitoring of emergency stop switches, safety doors or light barriers, for example. They are also essential in railway signalling equipment as well as in the controllers for passenger and goods elevators as well as in medical equipment. Our PCB relays are available in a great variety of different contact variants and construction forms and guarantee the highest switching safety with minimal dimensions.
