It is listed as a Header, Male Pins, Unshrouded type, meaning the pins are exposed after soldering — no shroud to guide or protect the mating plug, so alignment relies on the plug's own housing.
Through-hole mounting with solder termination — the 0.138" (3.50mm) contact tail length matches the board thickness plus solder fillet budget for a standard 1.6mm PCB.
This unshrouded header mates with a 3.50mm pitch terminal block plug that has female socket contacts. The plug must match the 2-position count and 3.50mm pitch; the header's unshrouded design means the plug's housing provides the alignment and locking.
The UL current rating is 2 A per contact at 150 V. This is a signal-level or low-power interconnect; derate if ambient temperature exceeds the 110°C operating maximum.
