2.3mm Unsealed – When to Use MG622226

The MG622226 is designed for protected, dry locations – under seat panels, inside instrument housings, or within enclosed switch boxes. For exposed locations subject to rain or water spray (underbody, engine bay, external lighting), use the waterproof FW series equivalent with IP68 sealing.

Frequently Asked Questions

Q: What is the mating female connector for MG622226?
A: The mating female housing in the same 2.3mm series is the MG622227 (4-pin female). Both use the same 2.3mm pitch terminal. Verify the female housing part number on your harness before ordering.

Q: Can I use MG622226 for a 12V headlight circuit?
A: Yes. A standard 55W halogen headlight draws approximately 4.6A at 12V – within the 10A per pin rating. However, for exposed headlight locations, use the waterproof FW series instead of the unsealed MG622226.

Q: How do I prevent terminal oxidation in an unsealed connector?
A: Apply a thin coat of dielectric grease (such as Dow Corning DC-4 or equivalent) to the terminal mating faces during installation. This prevents moisture and oxygen from reaching the tin-plated contacts and extends connector service life significantly.

Q: What crimping tool is needed for 2.3mm terminals?
A: Use a ratchet crimper rated for 18 AWG (0.5 mm²) terminals. The Engineer PA-09 or equivalent precision crimper is recommended for 2.3mm pitch terminals.
