In summary; the new DF57 Series, Wire-to-Board connector system from Hirose is an ultra-low profile design, which makes efficient use of printed circuit board real estate. The unique “Swing Lock” mechanism produces a very reliable connection that resists unwanted pull-out or un-mating. With an operating electrical current of up to 2.5 amperes per pin, the DF57 provides excellent current density for its size. The header design integrates solder wicking prevention. All materials are RoHS compliant.
