Description

Technical Field

[0002] Brake wear alarm sensors are often used in the brake units of vehicles to detect the thickness of easily worn parts in the brake units, ensure good braking performance of the vehicle, and improve vehicle safety. Brake wear alarm sensors usually include a plug-in terminal, a wiring harness consisting of wires or wires with heat shrink tubing, and a sensor head. The sensor head is located at the position of the easily worn parts of the brake unit. The wiring harness consisting of the wires is used to cooperate with the plug-in terminal to transmit the loop signal.
