1.2mm Pitch – Critical Handling

• Precision crimping mandatory: Use micro-crimper rated for 0.3mm² (22 AWG) – Engineer PA-09 or TE Connectivity 91516-1
• Wire seal integrity: 22 AWG wire must be used – larger gauge prevents seal compression and compromises IP68 rating
• Terminal insertion: Insert perfectly straight – angular insertion damages 1.2mm housing cavities

Frequently Asked Questions

Q: What is the mating male connector for 35126375?
A: Verify the male housing part number on your vehicle harness – it will be in the same 1.2mm series. Cross-reference OEM part number 35126375 in your vehicle's service manual.

Q: What crimping tool is needed?
A: Use a precision micro-crimper rated for 0.3mm² (22 AWG) – Engineer PA-09 or TE Connectivity 91516-1. Standard automotive crimpers will crush the 1.2mm terminal barrel.

Q: Can I use 20 AWG wire with this connector?
A: No. The rubber wire seal is sized for 22 AWG (0.3mm²) wire. Using 20 AWG or larger wire prevents the seal from compressing correctly, compromising the IP68 waterproof rating.
