Even redundant, secure emergency-stop chains are ineffective unless the contact block is accurately connected with the emergency-stop button. The patented safety contact blocks of Schlegel Elektrokontakt are the response to this danger that may occur e.g. due to a negligent assembly or a mechanical damage.
In such an emergency they ensure that the emergency function is activated and that the installation is immediately shutdown. It can only be started up again after trouble-shooting.
The contact blocks are available with screw connections or Faston terminals and do have positive opening contacts acc. to IEC60947-5-1. They can be supplied with one or two channels and also, once combined with the relative E-stop button, in a foolproof version acc. to EN60947-5-5 and EN418. The high-quality contact elements allow reliable switching even of low currents (5mA at 24V or less). They are available as conventional contact blocks as well as for the AS-Interface-Bus (Safety@Work).
