Hirose DF51K Connector, Custom Wire Harness Assembly
Hirose DF51K Series Connector
The DF51K Series is a compact 2mm pitch wire-to-board connector designed for high-density, reliable connections in demanding environments. Featuring a secure center lock mechanism for tactile mating confirmation, it offers THT/SMT mounting, straight/right-angle orientations, and single/double-row configurations (2–30 positions). Tin or gold plating options enhance conductivity, while polarization prevents incorrect mating. UL/C-UL certified and compatible with DF11 crimping tools, it supports 22–30 AWG wires and potting (up to 3mm for THT headers). Ideal for industrial automation, medical devices, robotics, and office equipment, its robust design ensures durability in high-vibration and harsh conditions. Combining versatility, ease of assembly, and high contact reliability, the DF51K Series streamlines connectivity solutions for space-constrained, mission-critical applications.
