2-Pin 2-967644-1 Waterproof 0.6mm Connector – Mercedes-Benz Signal Harness

Direct-fit replacement for TE Connectivity / AMP part number 2-967644-1, a 2-pin waterproof 0.6mm pitch connector used extensively in Mercedes-Benz signal harness applications. Unlike the unsealed 0.6mm series, this variant incorporates rubber wire seals for IP68 protection – making it suitable for exposed sensor locations on Mercedes-Benz platforms.

Mercedes-Benz Applications

• W204 C-Class (2007–2014): Interior sensor and control module signal connectors
• W212 E-Class (2009–2016): Instrument cluster and body control module harness
• W221 S-Class (2005–2013): Comfort system and ambient lighting control wiring
• W166 ML/GLE (2011–2019): Suspension and chassis sensor signal circuits
• Cross-reference: Verify OEM part number 2-967644-1 before ordering

Why 0.6mm Pitch Matters on Mercedes-Benz

Mercedes-Benz uses ultra-fine 0.6mm pitch connectors in high-density ECU and body control module (BCM) harnesses where space is critical. The 2-967644-1 is found in locations where multiple signal circuits must be routed through a compact connector block. Key considerations:

• Terminal fragility: 0.6mm terminals are extremely delicate – never use standard automotive crimpers. Use a precision micro-crimper rated for 0.3mm² wire.
• Waterproof variant: Unlike the standard 0.6mm series, the 2-967644-1 includes rubber wire seals – do not omit these during reassembly.
• Contact resistance: Mercedes-Benz BCM circuits are sensitive to contact resistance above 0.1Ω – clean terminals with contact cleaner before reconnecting.

Common Failure Symptoms

• Intermittent warning lights (SRS, ESP, comfort system faults)
• Erratic sensor readings on STAR Diagnosis / XENTRY
• Communication faults between control modules (U-codes)
• Ambient lighting or seat adjustment malfunctions

Frequently Asked Questions

Q: What is the mating male connector for 2-967644-1?
A: The mating male housing is 1-967644-1 (2-pin male, 0.6mm waterproof series). Both use the same 0.6mm sealed terminal (part number 925904-1 or equivalent sealed variant).

Q: Is this connector compatible with non-Mercedes vehicles?
A: Yes. The 2-967644-1 is a TE Connectivity standard part used across multiple OEMs. However, it is most commonly referenced for Mercedes-Benz applications. Verify by OEM part number for other vehicles.

Q: What crimping tool is required?
A: Use a precision micro-crimper for 0.3mm² (22 AWG) sealed terminals – such as the Engineer PA-09 or TE Connectivity 91516-1. Standard crimpers will crush the terminal and compromise the seal.

Q: Can I use this connector for 24V truck applications?
A: The housing is rated for 24V, but the 0.6mm terminal series is limited to 3A per pin – suitable for signal circuits only. Do not use for power circuits.
