HRS DF51K 20DS 2C 800 wire to board connector designed for mating and industrial equipment applications
Product Overview
The DF51K Series is a 2mm pitch, positive lock, wire-to-board connector designed for reliable and flexible board design. It features a positive lock mechanism for secure mating with a clear tactile click, preventing incomplete connections. The series offers a wide variation of straight and right-angle types in single and double row configurations, with gold and tin plating options to suit various application needs. Its design includes a visually and mechanically polarized system to prevent incorrect mating and is suitable for potting up to 3mm. The DF51K series uses the same crimp tools as the DF11 Series and is UL, C-UL certified. Applications include office equipment, industrial machinery, industrial robots, amusement equipment, and medical equipment.
