Fail-safe emergency stop switch
Georg Schlegel GmbH & Co. KG
Even redundant, safe emergency-off chains are ineffective unless the contact block is accurately connected with the emergency-off button. The patented, self-monitoring emergency-off contact blocks by Schlegel Elektrokontakt are the response to this danger that may occur e.g. as a result of a negligent assembly or a mechanical damage. In such a case they ensure immediate activation of the emergency-off signal and switching-off of the installation, which can be restarted only after successful 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 as well as - when combined with the appropriate emergency-off button - in a foolproof version acc. to EN60947-5-5 and EN13850. 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 AS-Interface application (Safety@Work).
