The 15 positions are fully loaded (all positions populated), so the pin count matches the circuit count on your BOM exactly. The UL94 V-0 rated black insulation (0.100" / 2.54 mm insulator height) meets the flame rating required for equipment inside an enclosure.
This unshrouded header mates with standard 0.100" (2.54 mm) pitch female socket receptacles — the matching BERGSTIK II receptacle housing or any industry-standard 2.54 mm pitch socket strip. The overall contact length is 1.238" (31.45 mm), with a mating length of 1.043" (26.49 mm) and a solder post length of 0.095" (2.41 mm). The short post is designed for through-hole soldering to a PCB; the board thickness and hole diameter must accommodate that post length for proper solder fillet formation.
