  • Snapping-on a DIN rail is also possible with DIN rail bus connectors (gold-plated contacts ensure high product quality).
  • Because of the bus connectors, the supply and signal voltages are looped through. Individual modules can be removed without interrupting connection to the other devices.
  • Spring cage and screw-type terminals for wiring. The terminals are inserted during the soldering process, so the complete module can easily be inserted into the enclosure.
  • Large front surfaces for display or operating units, protected by a collapsible hood. The front panels can easily be processed and printed.
  • The enclosure elements are snapped onto each other, the foot catch is mounted, the front panel is plugged in, and the crystal-clear hood is fixed.
  • Optional is a functional earth ground contact for use with the conductive connection between PCB and DIN rail.
  • CNT...TB: Openings for DIN rail bus connectors.
