Custom 2/4/8-Pin JST Wiring Harness

Product Overview

The Custom 2/4/8-Pin JST Wiring Harness is a high-performance connectivity solution designed for demanding electrical applications, featuring premium silicone wire as the core conductive component. Developed by the SUYI brand, this wiring harness leverages the exceptional properties of silicone insulation to deliver reliable performance in extreme temperatures and harsh environments. It integrates standard 2-pin, 4-pin, and 8-pin JST connectors—a globally recognized standard for compact, secure electrical connections—making it ideal for devices requiring stable signal and power transmission. Whether for household appliances, industrial equipment, or electronic systems, this harness ensures long-term durability and consistent functionality, addressing the core needs of both OEMs and end-users.

Key Features

Superior High Temperature Resistance: The silicone wire in the harness operates reliably within a temperature range of -50°C to 180°C, maintaining insulation integrity even in high-heat scenarios (e.g., near electric heating elements).

Strong Corrosion Resistance: Silicone insulation resists erosion from common chemical substances, extending the harness’s lifespan in industrial or humid environments.

Excellent Fire Resistance: The silicone wire retains its insulation effect for an extended period during fire incidents, reducing safety risks in critical applications.

Exceptional Flexibility: With good softness and elasticity, the harness accommodates large bending radii, suitable for devices with limited installation space (e.g., small household appliances).

Secure JST Connector Compatibility: Equipped with genuine JST connectors (2/4/8-pin), ensuring tight, low-resistance connections that minimize signal loss or power disruption.

Wide Voltage Adaptability: Supports standard low-voltage applications (up to 300V), matching the power needs of most electronics and small electrical devices.

Industrial-Grade Durability: The harness undergoes strict quality checks to withstand vibration and mechanical stress, ideal for motor lead wires and industrial equipment.

Easy Installation: Pre-terminated JST connectors enable plug-and-play installation, reducing assembly time for manufacturers.
