Hirose has launched the DF57 range of headers, sockets and crimp contacts for use with LED displays, touch panels, small motors, industrial robots, LED lighting modules and digital cameras.

The connector occupies 18 or 23mm approximate board space for the two- and three-contact position respectively and the height profile is 1.4mm.

Power performance is not compromised by the small size and a 2A current rating per contact is realised.

Hirose’s ‘Swing Lock’ offers a double-locking mechanism to ensure reliability During the mating operation, the receptacle is inserted into the header at a slight angle by offering the cable end in first.

This engages with the positive lock.

The mating operation is then finished by ‘swinging’ the other end of the receptacle in to engage with the friction lock, which provides a tactile click sensation to confirm correct mating.

It also prevents the receptacle from floating.

The positive lock can withstand a minimum of 5N of cable pull force, ensuring that the socket can not be accidentally removed from the header.

A small lever makes the unmating process very quick and easy.

Durability is achieved with 30 mating cycles.

Blade contacts are utilised to prevent damage against any cable wrenching forces.

These are positioned within a strengthened housing lance to increase the retention further.

An effective contact mating length of 0.42mm ensures good electrical continuity.

The termination contacts on the header are fully moulded into the insulator to eliminate any gaps to prevent solder wicking.

This range is available in two and three positions, with a four-position currently in development.

These can accept AWG 30-28 cable sizes.
