The TE Connectivity 1-1971896-3 is a 3-position, single-row vertical header from the Dynamic Series, designed for board-to-cable/wire power interconnects. It carries a 5.00 mm pitch — wide enough to handle the 20 A per circuit rating without crowding the board — and the full 4-wall shrouding protects the silver-plated tab contacts from damage during mating. The latch holder on the shroud locks the mating receptacle in place, so vibration on a factory floor or in a vehicle won't work the connection loose. Silver plating on both the mating surface and the solder post keeps contact resistance low at this current level, though it's not intended for frequent reconnects — this is a set-and-forget power joint.
Construction and environment
The housing is molded from polyamide (nylon) with a UL94 V-0 flammability rating. The operating range of -40°C to 120°C covers industrial cabinet heat soak and cold-start conditions.
