Product details

Unshrouded Push-Pull — No Locking Latch

The 90122-0770: This header has no shroud and uses a push-pull fastening mechanism — there is no latch or lock to hold the mating connector. For applications where the connector pair stays mated and stationary, the push-pull interface is simple and low-cost.

Automotive and General-Purpose Rating

The C-Grid III 90122 series is rated for automotive and general-purpose applications. The automotive rating implies the connector meets thermal cycling and vibration profiles beyond basic commercial grade — useful for under-hood or cabin electronics that see temperature swings.

Frequently asked questions

What is the pitch and position count of Molex 90122-0770?

The 90122-0770 has 20 positions in two rows at a 2.54mm (0.100") pitch, with the same 0.100" row spacing. This is the standard 0.100-inch grid, so it mates with any 20-position 2.54mm pitch receptacle on the same grid.

Does 90122-0770 have a locking latch?

No. The 90122-0770 is an unshrouded header with a push-pull fastening mechanism. There is no latch or locking ramp. For vibration-prone environments, a shrouded header with a locking latch would be a different selection.
