It is a free-hanging, in-line housing designed for crimp termination — the female socket contacts are ordered separately and must be added to complete the connector assembly. The locking ramp fastening provides positive retention when mated with the corresponding pin header, making this housing suited for wire-to-board interconnect in harness assemblies where vibration resistance matters. ## What the 2.00 mm Pitch and Locking Ramp Mean for Assembly The 2.00 mm pitch is tight enough for reasonable board density but leaves enough room between contacts for the crimp barrel and wire insulation — no need to strip back to the conductor for clearance. The dual-row layout with 0.079\" (2.00 mm) row spacing means the mating header footprint occupies a compact 20-position rectangle on the PCB, which keeps routing channels open for other traces. The locking ramp engages audibly when the housing is fully seated onto the header; that tactile click confirms the mate before the harness is tied down, and it prevents the connector from walking loose under cable strain or vibration.","metaTitle":"Hirose DF51K-20DS-2C(800) SignalBee Receptacle Housing","metaDescription":"Hirose DF51K-20DS-2C(800) SignalBee DF51 receptacle housing, 20 positions, 2.00mm pitch, dual-row, locking ramp.
