The free-hanging (in-line) body means this plug sits on the cable end, not on a board — it mates with a Mark II receptacle such as the 1-1703095-1.
The IDC termination accepts discrete wire — the insulation is pierced by the slot as the cable is pressed in, making contact with the silver-plated tab. No individual contact crimping is needed; the whole 3-conductor cable is terminated in one press operation.
The pitch is 0.197" (5.00 mm), single row, matching the Mark II receptacle family.
Yes, it is ROHS3 compliant.
It is a 3-position IDC plug for discrete wire, used as a wire-to-wire or wire-to-board interconnect in the Mark II series. The latch lock suits it for applications where vibration resistance matters.
