BCZ 3.81/02/180 SN OR BX PRT Weidmüller Interface GmbH & Co. KG Klingenbergstraße 26 D-32758 Detmold Germany www.weidmueller.com Product image Female socket connectors with clamping-yoke screw sys- tem for connecting wires. Three wire-outlet directions are available and provide flexi- ble connection-level design options:

  • 180° wire parallel to plugging direction
  • 90° wire perpendicular and above plugging direction
  • 270° wire perpendicular and below plugging direction There are three housing shapes, covering many different requirements, to choose from:
  • Standard housing without flange
  • Flange with screw (F)
  • Flange featuring Weidmüller's patented release latch (LR) for lock-and-release latching with no strain and no tools needed. Weidmüller's 3.81-mm-pitch (0.15 inch) plug-in connec- tors are compatible with the layouts of customary connec- tors and offer space for labelling and coding.
