AMP 2.8mm Series – Technical Notes

The AMP 2.8mm series is rated for up to 13A per pin – suitable for medium-current sensor and actuator circuits. Key handling notes:

• Terminal insertion: Insert straight and feel for the audible click of the terminal lock. Angled insertion damages the housing cavity.
• Secondary lock: Some 1-929504-1 housings include a secondary terminal position assurance (TPA) lock – ensure it is fully engaged after terminal insertion.
• Contact resistance: Any reading above 0.3Ω indicates terminal corrosion – clean with electrical contact cleaner before reconnecting.

Frequently Asked Questions

Q: What is the mating male connector for 1-929504-1?
A: The mating male plug in the same AMP 2.8mm series is 1-929505-1 (4-pin male). Verify the male housing part number on your vehicle harness before ordering.

Q: What crimping tool is needed for AMP 2.8mm terminals?
A: Use a ratchet crimper rated for 18 AWG (0.5 mm²) – Engineer PA-09 or equivalent precision ratchet crimper for 2.8mm AMP terminals.

Q: Is this connector waterproof?
A: The standard 1-929504-1 is unsealed. For waterproof applications, use the sealed variant with individual wire seals.
