The green housing and closed-end feature mean the mating header can only go in one way, which saves a rework cycle on the line.
This is an IDC connector — no crimp tool, no loose terminals to handle. You strip the 28 AWG wire to length, lay it across the slot, and press the cover down. The insulation is displaced by the tin-plated contact tines, making gas-tight connection. The free-hanging mount means it lives on the wire bundle, not on the board — the mating pin header takes the soldering.
The 08ZR-8M-P mates with a JST ZR series pin header, 8 positions, single row, 0.059" pitch. The female socket contacts accept the header pins. The closed end aligns the header — push it home until the latch clicks. On the harness side, the green housing is a visual cue: if you're running multiple ZR receptacles in the same bundle, the color keeps the 8-position line distinct from the natural or white variants.
Position Count Comparison vs Siblings
The 08ZR-8M-P carries 8 positions. If your BOM calls for 7 or 9 circuits, the same ZR series offers the 07ZR-8M-P (7 positions) and 09ZR-8M-P (9 positions) — same pitch, same IDC termination, same 28 AWG wire gauge. The 08ZR-3H-P is also 8 positions but in a natural housing and accepts 30 AWG wire, so it's a different wire-size build. Match the position count to your circuit count and the wire gauge to your cable spec.
