5.00 mm pitch, 2-position shrouded header with latch
The 3-1971845-2: This is a 2-position, single-row header on 5.00 mm pitch — the board footprint is wide enough to route a 5 mm trace between pads if needed. The shroud is a full 4-wall enclosure that protects the rectangular tab contacts during handling and prevents misalignment when mating with the cable receptacle. Tin-on-tin contact finish — rated for the typical 20–30 mating cycles of a field-service or production interconnect.
Through-hole solder termination, glow wire ready
The header terminates through-hole with a 0.138" (3.50 mm) post length — long enough for a 1.6 mm board with a good solder fillet on the far side. Glow wire compliant per the feature list — this matters for appliance and lighting applications where the connector must survive a glow-wire ignition test without sustaining flame.
