The through-hole solder tails (0.132" post length) mount to the PCB, while the board hooks provide additional mechanical retention during wave soldering and against cable strain. Rated 2.5A per contact at 250VAC, this is a signal-power interconnect suitable for control, sensor, and low-current distribution within an enclosure.
It is ROHS3 compliant and carries UL94 V-0 flammability rating on the nylon housing.

The pinout follows the standard KK254 layout — position 1 is typically marked on the housing. For exact footprint dimensions, refer to the product drawing.
Within the KK254 series, the key differentiators are circuit count (5 positions here), plating (tin vs gold), and features such as board hooks. A 10-position version would share the same pitch and current rating but occupy a longer PCB footprint.
