4-Pin Unsealed 0.7mm Male Connector – Motorcycle & Automotive Fine-Pitch Signal Harness

A 4-pin unsealed 0.7mm pitch male connector for motorcycle, scooter, and automotive fine-pitch signal harness applications. The 0.7mm pitch sits between the ultra-fine 0.6mm and the standard 1.2mm series – used in high-density ECU and instrument cluster harnesses where space is at a premium but slightly higher current capacity than 0.6mm is required.

Key Specifications

• Pin Count: 4
• Gender: Male plug (with wire)
• Terminal Pitch: 0.7mm

• Wire Gauge: 22 AWG (0.3 mm²)
• Wire Length: 5.5 inches (140 mm)
• Housing Material: PA66 nylon
• Terminal Material: Copper alloy, tin-plated
• Current Rating: Up to 3A per pin (signal circuits only)
• Voltage Rating: 12V / 24V DC

Applications

• Motorcycle ECU signal input/output harness
• Scooter instrument cluster signal wiring
• ABS control module signal connectors
• Fuel injection ECU harness connections
• Automotive BCM and TCM signal harness
• Airbag / SRS module signal connectors

0.7mm Pitch – Critical Handling

• Precision crimping mandatory: Use micro-crimper rated for 0.3mm² (22 AWG) – Engineer PA-09 or TE Connectivity 91516-1
• Strip length: 2.5–3.0mm exactly – too long risks inter-pin shorts at 0.7mm spacing
• ESD protection: Use wrist strap when handling ECU/ABS circuit connectors
• Terminal insertion: Insert perfectly straight – angular insertion damages 0.7mm housing cavities

Frequently Asked Questions

Q: What is the difference between 0.6mm and 0.7mm pitch connectors?
A: The 0.7mm pitch provides slightly more inter-pin spacing than 0.6mm, allowing marginally higher current capacity (up to 3A vs 2A per pin) and easier terminal insertion. Both are fine-pitch signal connectors – not suitable for power circuits above 3A.

Q: What crimping tool is needed?
A: Use a precision micro-crimper rated for 0.3mm² (22 AWG) – Engineer PA-09 or equivalent. Standard automotive crimpers will crush the 0.7mm terminal barrel.
