The JST 07ZR-8M-P is a 7-position receptacle from the ZR series, terminated via IDC to discrete 28 AWG wire. The green housing is a visual cue on the line; the closed-end feature prevents wire over-insertion during assembly.
This receptacle accepts only 28 AWG discrete wire — no other gauge fits the IDC slot. The IDC termination pierces the insulation on insertion, so no stripping or crimping is needed; a simple hand press or bench tool seats the wire. The closed end acts as a wire stop, so the assembler gets consistent insertion depth without measuring. Free-hanging (in-line) mounting means the connector floats in the harness rather than locking to a panel — typical for internal wiring where the harness routes to a board-mounted header.
The 7 positions at 1.50 mm pitch define the mating header footprint. A 7-circuit header at this pitch is a standard JST ZR series male pin header — the 07ZR-8M-P is the receptacle half. Compared to the 6-position sibling (07ZR-6M-P), the difference is one circuit: the same pitch, same wire gauge, same IDC termination, same tin finish. Choose the 7-position when your BOM calls for seven signal lines; the 6-position covers six. No other specs shift between the two — it is purely a circuit-count decision.
