DC Buzzer Wire Harness For Alarm And Security Devices

A DC harness kit for high decibel buzzers and electronic alarm sounders, used in EV cabins, home security panels and telecom equipment. The sounder is usually mounted away from the board, so the harness carries the drive circuit to it with a latched connector at both ends.

  • Pre-terminated buzzer leads remove hand-soldering at final assembly
  • Latched connectors let the sounder be replaced without touching the board
  • Drive circuit routed as a discrete pair keeps the alarm line clear of noise
  • Built for DC alarm and sounder circuits in vehicles and panels
