Product details

Grace Inertia header for board-to-wire connections

Its 0.098" (2.50mm) pitch and shrouded 4-wall housing mate with the corresponding Grace Inertia receptacle, locking via the latch holder for vibration resistance.

Pitch, position, and mounting footprint

The 2.50mm pitch and two positions keep the board footprint compact.

Voltage rating is 50V, suitable for signal-level or low-power distribution.

For high-cycle reconnect duty, gold-plated alternatives in the series would be a better fit.

Housing materials and safety compliance

The yellow insulation color aids visual identification in a harness.

Frequently asked questions

What is the mating connector for 2-1971800-4?

Mates with the Grace Inertia receptacle housing (e.g., 2-1971796-x series) using the appropriate crimp terminals. Confirm the circuit count and wire gauge match your application.

Is 2-1971800-4 RoHS compliant?

Yes, ROHS3 compliant.

What is the current rating of 2-1971800-4?

Current rating varies by wire gauge used in the mating receptacle — the header itself does not impose a fixed limit. Derate based on the actual wire size and ambient temperature.

Are there alternatives to 2-1971800-4?

Within the same Grace Inertia series, other position counts and right-angle versions exist. The closest functional peer outside the series would be a 2.50mm pitch, 2-position, shrouded header with latch — confirm pitch, pinout, and locking mechanism before substituting.
