The Hirose DF51-16DS-2C is a 16-circuit receptacle housing from the SignalBee™ DF51 series, built for wire-to-board harness applications where a compact 2.00 mm pitch keeps the board footprint tight. This is the dual-row version — 8 positions per row — with a 0.079" (2.00 mm) row spacing that mirrors the pitch, so the contact pattern is a clean 2×8 grid. The housing is free-hanging (in-line), meaning it terminates a cable assembly that mates to a board-mounted pin header. The detent lock provides audible and tactile feedback when fully seated, holding the pair together under vibration in industrial cabinets or automotive interior harnesses.
Contacts Are Sold Separately — Order the Right Crimp Terminal
The DF51-16DS-2C ships as an empty housing — contacts are not included. You need to order the matching Hirose DF51 series female crimp terminals separately, then terminate them onto the wire before inserting into the housing cavities. The crimp termination means each contact is individually crimped to the conductor, then pushed into the housing until the retention lance locks it in place.
Mating Header and Keying
This receptacle mates with the corresponding Hirose DF51 series pin header — a 2×8, 2.00 mm pitch, dual-row through-hole or SMT header. The detent lock on the housing engages a matching ramp on the header shroud, so the pair stays mated without a secondary latch. The black colour is standard for the DF51 series; no keying variant is listed, so any DF51 header of the same position count and pitch is a functional mate.
