Right-Angle Header for Board-Edge Wiring
The 3-644894-5: The friction lock provides positive retention against moderate vibration — common in lighting fixtures and general-purpose equipment where a full latch isn't required but accidental disconnection is unacceptable.
The 250VAC voltage rating covers standard mains and low-voltage lighting circuits.
The header mates with CST-100 receptacle housings (e.g., 3-644895-x series) using standard 22-26 AWG crimp terminals. The 0.130" (3.30mm) post length is designed for through-hole soldering on 1.6mm thick PCBs — the post protrudes enough for a reliable solder fillet without excessive lead trimming. The 0.280" (7.11mm) mating pin length provides sufficient wipe for a clean contact interface. Termination is solder — wave or hand-solder. No press-fit option. The right-angle body keeps the mating face perpendicular to the board edge, so plan the board layout with clearance for the receptacle and cable exit.
