Positive lock wire to board connector HRS DF51-24DS-2C with 2mm pitch and wide configuration options
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 tactile feedback, a wide variation of configurations including single-row and dual-row options with gold and tin plating, and a secure side-locking design for compact equipment. The connectors prevent incorrect mating and are compatible with DF11 Series contacts and crimping tools. They are suitable for potting and are UL, C-UL certified.
