16-Position 1.25mm Pitch Plug for Discrete Wire Harnesses
The Kyocera AVX 109257016001003 is a 16-circuit plug from the 9257 series, designed for discrete wire-to-board or wire-to-wire interconnects where a compact 0.049" (1.25mm) pitch keeps the board footprint small. The free-hanging (in-line) mount and solder cup termination make this a cable-end connector — it terminates individual wires into the plug body, not onto a PCB. The black housing is a single-row, 16-position layout, and the non-gender-specific contact type means the mating half is a complementary receptacle from the same 9257 series. The 1.25mm pitch is the tightest dimension on this part — it sets the wire-to-wire spacing and the mating header's pad pitch. For a 16-circuit run, that pitch keeps the connector body narrow enough for dense harness routing inside enclosures or along cable trays. Gold contact finish at 31.5µin (0.80µm). Solder cup termination for each wire.
This plug mates with a 9257 series receptacle of the same 16-position, 1.25mm pitch layout. The non-gender-specific contact design means the mating receptacle carries the complementary contact geometry — confirm the receptacle order code against the same 9257 series for a guaranteed fit. The free-hanging mount on both halves allows the mated pair to float in the harness, reducing strain on the solder joints.
