Automotive Buzzer Cable Harness, 155mm

Shenzhen Fubang Wiring Harness Co., Ltd. is a full-service manufacturer focusing on the development, precision assembly and strict performance testing of wiring assemblies for automotive maintenance tools, on-board electronics and industrial control devices. We build standardized automated production workshops and implement full-process quality supervision covering raw material inspection, semi-finished processing and finished electrical verification. As an experienced supplier of all kinds of custom cable assembly and wiring harness, we can flexibly adjust wire gauge, total length, connector collocation and soldering process according to clients’ unique equipment layout and signal transmission requirements. Our production line complies with automotive industry standards, enabling us to produce stable, temperature-resistant automotive wiring harness that can withstand oily, damp and high-low temperature working environments in repair shops and industrial sites. Every batch of finished goods passes complete electrical testing, and all raw materials meet RoHS environmental specifications to deliver reliable connection solutions for global equipment manufacturers.

This buzzer signal wiring harness with a fixed overall length of 155mm is specially designed for audio prompt modules of vehicle diagnostic and key programming equipment, providing stable power supply and signal conduction for buzzer components. Unlike long-distance OBD extension cables or multi-channel split wiring assemblies, this short-range assembly adopts UL1007 18AWG red and black wire cores, with clear color separation to avoid misconnection during assembly. One end is equipped with a mounting-type plastic buzzer with reserved fixing lugs for easy installation inside equipment casings; the other end adopts MX 3.0 series plastic connector for quick plug-and-play connection with main control boards. The welding joints between wire and buzzer pins are wrapped with heat shrink tubes for insulation and anti-breakage protection, effectively preventing open circuit risks caused by frequent vibration and disassembly.

During processing, this buzzer cable strictly follows the production norms of custom wiring harness. Each wire is cut to precise dimensions, stripped to uniform core length and soldered with standardized tin filling to guarantee stable contact. After assembly, every harness undergoes DC 300V withstand voltage test, insulation resistance test and continuity inspection, screening out products with short circuits, poor contact or excessive conduction resistance. The outer PVC insulation layer features excellent abrasion resistance, which can maintain stable electrical performance under long-term vibration inside compact equipment shells.

Compact in size and easy to install, this buzzer wiring assembly has become a common matching accessory for vehicle anti-theft programming tools, industrial reminder alarms and access control prompt systems. Our technical team supports personalized modification on the basis of this standard design: adjusting wire length, switching connector types or matching buzzers with different sound volumes. Drawing on our rich experience in manufacturing automotive wiring harness and small signal custom wiring harness, we can provide one-stop assembly solutions from sample proofing to mass delivery, winning long-term cooperation from automotive electronics labs and professional maintenance equipment brands around the world. Beyond vehicle diagnostic devices, this assembly can also be adapted to household control panels, small industrial sensors and DIY electronic reminder equipment, delivering steady audio signal transmission for various low-voltage electronic devices.
