DF51 2mm Pitch Wire-to-Board Connectors

Hirose Electric DF51 wire-to-board connectors are 2mm pitch, positive-lock, crimp-type connectors. DF51 connectors feature a side-lock design that enables easy operation and reliable connection. These single- and double-row Hirose connectors also provide high contact lance strength, preventing contacts from pulling loose while wrenching the cables. This Hirose series works with 30AWG to 22AWG cables and offers 0.5A to 2A rated current and 250V_AC/DC rated voltage.
