Type EXR40


The EXR40 is a wiper-water relay and has been optimised for the windscreen wiper application for passenger cars and commercial vehicles.

  • Save time by using well-proven components
  • Flexible use with one variant for both on-board electrical network voltages
  • Reduce complaints as icy windscreen wipers do not cause a fuse to trip

The EXR40 wiper-water relay is suitable for standard automotive relay sockets to ISO 7588 and is available for DC 12 V and DC 24 V applications.
