4-Position Vertical Header for Wire-to-Board Applications
1-1971906-2 is a 4-position, 3.30mm-pitch, 2-row vertical header from the Grace Inertia GIC series by TE Connectivity AMP Connectors. It is a Board to Cable/Wire style header with a shrouded 4-wall design and a latch holder fastening system, meaning the mated receptacle is held positively against vibration and cable pull. The header mounts through-hole with kinked pin solder tails (0.118" post length) and carries tin-plated square male pins on both the mating and post side. The insulator is natural polyamide 6/6 glass-filled, rated UL94 V-0, and the operating temperature range is -30°C to 105°C.
Vibration-Resistant Latching and Shroud Detail
The shrouded 4-wall enclosure protects the pins from damage during handling and mis-mating, while the latch holder provides a positive lock with the mating receptacle — a feature that matters in industrial or general-purpose equipment where cable strain or machine vibration could otherwise separate the connection. A board guide on the header aids alignment during assembly, reducing the risk of bent pins when the mating half is inserted off-angle.
