DF57H-3P-1.2V(21)

The DF57 series low-profile swing-lock Board-to-Wire Connector. A swing-lock structure, featuring unique connection method, reinforces the lock structure of the electric cable side with a structure resistant to tough electric cable routing and disengagement of cables under load. In addition, the connection surface has a guide insertion to facilitate insertability (patented). When connecting, the header connector secures the moulded-lance. Play of moulded lance is prevented for added strength. Despite the low-profile design, with a stacking height of 1.4mm, an effective mating length of 0.42mm is achieved. The structure features two-point contact terminal geometry with high contact reliability. Insert guide key guides the crimp socket to the correct mating position and prevents misalignment, which improves mating operation and prevents possible connector breakage with incorrect mating. The integral moulding eliminates any gap between the terminals and case to prevents solder wicking.
