Board-to-board receptacle, 4 positions, 0.100" pitch
It mates with matching 0.100" pitch pin headers to create a board-to-board interconnect. The through-hole termination with kinked solder pins provides mechanical retention during wave soldering — the kink holds the part in place before the solder joint forms.
Gold mating finish at 31.5 µinch — cycle life for test and programming
The mating contact surface is gold over phosphor bronze, with a gold thickness of 31.5 µinch (0.80 µm).
Glass-filled polyester housing, UL94 V-0 flame rating
For equipment inside an enclosure — industrial controllers, test equipment, power supplies — this V-0 rating satisfies the standard flame-retardant requirement without a material waiver.
