BCL-SMT 3.81/02/90LFI 1.5SN BK BX Weidmüller Interface GmbH & Co. KG Klingenbergstraße 26 D-32758 Detmold Germany www.weidmueller.com Product image The inverted BCL-SMT socket block for the PCB offers three significant advantages:

  • The BCL-SMT offers touch-safe security on the PCB which makes it ideal for live, current-carrying outputs.
  • The BCL-SMT widens the range of applications with board-to-board connections between component assemblies.
  • The BCL-SMT is reflow-compatible and can be seam- lessly integrated into the automatic assembly and sol- dering process. Two outlet directions give you a choice of position and thus more design flexibility.
  • 180° standing
  • 90° recumbent Two housing variants are available for the BCL-SMT:
  • Without flange
  • With inverted solder flange ("LFI", with nut)
  • • Fastened to PCB without additional screw
  • Fastened with screw to the SCZ FI 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.
