Modular electronics housings from the BC series represent future-oriented applications in building automation. The electronics housings impress thanks to their modern design, versatile PCB connection technology, and efficient DIN rail connector. BC housings are suitable for direct wall mounting or use in installation distributors in accordance with DIN 43880.

Your advantages:

  • Maximum flexibility, thanks to free choice of PCB connection technology and various overall widths
  • Standard-compliant housing and installation dimensions for use in installation distributors
  • Fast installation or module replacement without breaking up the topology – possible thanks to the HBUS connector
  • 16-pos. DIN rail connector for serial and parallel modular communication
  • Freedom in device development, as the PCB can be aligned in three spatial directions
  • Optimum adaptation to device requirements, thanks to different cover versions

Complete flexibility
