Board-to-Wire Header for Industrial Harnesses
The 1-1971906-4: Its 3.30mm pitch and 8 positions in two rows suit medium-density power and signal interconnects in industrial panels and general-purpose equipment.
Pinout and Mating Connector
This header has all 8 positions loaded in a 2-row arrangement with 0.205" (5.20mm) row spacing. The pinout is a standard dual-row matrix: row A (positions 1-4) and row B (positions 5-8), with pin 1 typically marked on the housing by a chamfer or molded indicator — watch pin-one every press when terminating the harness. It mates with the corresponding Grace Inertia receptacle housing (TE part number 1-1971905-4 or equivalent), which accepts crimp terminals for 20-24 AWG wire.
With the tin-plated mating contacts, the practical per-circuit current is typically 5-7 A at 30°C rise when using 20 AWG wire, but the actual limit depends on the terminal and wire combination used in the mating half.
