Power relay with plug-in connector (HDSCS)

reliable and robust connection technology even under toughest requirements

Our power relays are designed to withstand the tough requirements of the commercial vehicle industry, especially for construction and agricultural machinery. With the new plug-in connector compatible with the HDSCS series we are now also part of the connection technology in modern on-board electrical systems.

Reliable and robust connection technology even under toughest requirement

The plug-in connector is made of robust thermoplastic with flammability class UL94 V0 and has an integrated secondary interlock with poka-yoke principle. Even under the toughest conditions the control connections can no longer come loose.

The cables can already be precut. During final assembly of the vehicle they are only to be plugged in and locked. Special tools such as tightening torques, Torx bits, crimping tools for cable sockets etc. are no longer required during final assembly.
The reverse polarity protected plug-in connection ensures a clear assignment of the control contacts.

The plug-in connector provides a robust and save connection. It is protected with IP 5k4 against penetrating dust and water.

Power relays with plug-in connector (HDSCS-series):

Typical applications

  • Main disconnectors for buses, trucks, construction machinery, agricultural vehicles and forestry equipment as well as specialty vehicles
  • High performance circuit breakers for large consumers such as air conditioning, compressors, electrical heating


  • ISO 16750
  • IATF 16949
  • ECE R118
  • ECE R10

Saves time and costs

  • through quick and fault-free mounting
  • thanks to isolation of the control contacts from environmental influences
  • through high resistance against vibration and mechanical stress
