HRS DF51 30DS 2C positive lock 2mm pitch wire to board connector supporting 22 to 30 AWG cable range
DF51 Series 2mm Pitch, Positive Lock, Wire-to-Board Connector
The DF51 Series is a 2mm pitch, positive lock wire-to-board connector designed for reliable and secure connections. It features a positive lock mechanism that provides a clear tactile click and ensures complete mating, preventing incomplete connections. The series offers a wide variation of configurations, including single-row and dual-row options in straight, right-angle, and in-line types, with gold and tin plating choices to suit various application needs. Its secure side-locking design contributes to compact and thin equipment designs. The connectors also incorporate visual and mechanical polarization to prevent incorrect mating. Compatible with DF11 Series contacts and crimping tools, the DF51 series supports a wide cable range of 22 to 30 AWG and is suitable for potting applications. Branch adapters are also available.
