Introduction
The DF61 Series from HIROSE is a compact, wire-to-board connector specifically engineered for low-profile power source applications. Its standout feature is a reinforced Swing-Lock structure that securely cradles the wire-side plug, providing exceptional resistance to disengagement from handling strain or accidental loads. This reliability is further enhanced by a metal-reinforced header lock that increases retention force between the plug and header upon mating. Despite its small 2.2mm pitch, the connector boasts a high voltage rating of 350V and can carry currents of up to 5 amps per pin (with 22AWG wire), making it ideal for power-hungry yet space-constrained devices. Key design advantages include a one-piece molded header to prevent solder wicking and the use of highly conductive materials for low contact resistance. The DF61 Series is well-suited for a wide range of portable and digital equipment, including laptop and tablet computers, digital cameras, LED lighting, and power supply units, offering a robust and reliable power connection solution.
