Secure wire to board connector HRS DF51-3EP-2C with 2mm pitch positive lock and side locking mechanism
Product Overview
The Hirose DF51 Series is a 2mm pitch, positive lock, wire-to-board connector designed for reliable and secure connections. It features a positive lock mechanism for clear tactile feedback, preventing incomplete mating. With a wide variation of configurations, plating options, and a secure side-locking design, the DF51 Series offers flexibility for compact and thin equipment. It also prevents incorrect mating through visual and mechanical polarization, uses the same contacts and crimping tools as the DF11 Series, and is suitable for potting applications. Certified by UL and C-UL, it is ideal for office automation, industrial machinery, robots, amusement equipment, and medical equipment.
