Product details

Board Footprint and Routing

The 77311-127-11LF: The single row keeps the board edge narrow, useful for tight layouts where every millimeter of board real estate counts.

Unshrouded — What It Means for Mating

This saves board space and cost, but the header pins are exposed and can be bent if the cable assembly is not guided in straight. The push-pull fastening type is standard for unshrouded headers; no locking latch, so in high-vibration environments a secondary retention method (like a wire-to-board housing with a lock) is worth planning for.

Current and Temperature Ceiling

For signal-level loads (under 1 A), the margin is generous and the connector runs cool.
