It terminates discrete wires — not ribbon cable — using insulation displacement contacts, so stripping and crimping are eliminated on the assembly line. The 0.197\" (5.00mm) pitch gives enough spacing for 300 V to 600 V class wiring in industrial control panels or appliance harnesses. Silver contact finish is standard here, which provides good conductivity but lower mating cycle life than gold — expect it in a semi-permanent or low-cycle-count interconnect rather than a field-service disconnect. The plug is free-hanging (in-line), mates with the matching Mark II header, and uses a latch lock for retention. The closed-end feature means the housing has a solid back wall — no pass-through for wire tails or daisy-chaining. Typical applications are internal power or signal wiring in commercial equipment, vending machines, and HVAC controls where the 5.00mm pitch matches the terminal block spacing. ## Procurement Bottom Line Obsolete part, no direct factory replacement on record. Confirm the mating header part number and wire gauge before the order is placed.","metaTitle":"TE Mark II 2-2178661-4, 4-Pos IDC Plug, 5.00mm, Obsolete","metaDescription":"TE Connectivity Mark II 2-2178661-4 4-position IDC plug, 5.00mm pitch, silver contacts, latch lock.
