Hirose DF51 Connector, Custom Wire Harness Assembly

DF51 Connector

 

The DF51 Series is a UL/C-UL-certified, 2mm-pitch connector offering secure, high-density connections for compact systems. Its positive-lock mechanism ensures reliable mating with tactile feedback, while configurations include straight, right-angle, and in-line designs in single-row (2–7 positions) and dual-row (4–30 positions). Compatible with DF11 Series contacts and crimping tools, it supports 22–30 AWG cables and features gold/tin plating options. Space-saving headers and low-profile right-angle types suit thin devices, with potting capability (3mm) for environmental protection. Branch and composite adapters simplify power/signal distribution. Rated for -55°C to +105°C and vibration/shock resistance, it is ideal for industrial automation, robotics, medical equipment, and office devices. Combines versatility, durability, and error-proof polarization for demanding applications.
