SCZ 3.81/04/180FI SN OR BX Weidmüller Interface GmbH & Co. KG Klingenbergstraße 26 D-32758 Detmold Germany www.weidmueller.com Product image The inverted SCZ pin plug with clamping-yoke screw con- nection is designed for straight wire connections in 3.81- mm pitch. It can be used in two ways:

  • for wire-to-wire connections together with the BCZ
  • as a mating plug for the touch-safe BCL socket block on the PCB. The SCZ is available in four different versions:
  • Without flange ("G", closed)
  • With standard flange ("F", with socket nut)
  • With inverted flange ("FI", with screw)
  • and with Weidmüller's patented release latch for a tool- free, no-strain disconnect The SCZ provides space for labelling and can be coded.
