Introducing the HIROSE DF57H Series, 1.2mm Pitch, Wire-to-Board Connector for Power Supplies, samples available from Anglia

Date Published : 09/02/2021 Share with:

HIROSE, a world-class manufacturer in connectors has launched the new DF57H range of headers, sockets and crimp contacts to meet with the requirement for smaller yet better performing connectors.

The DF57H series connector has been designed with space saving in mind, the two position for example, only occupies 18mm² approximate board space. The lowest height profile connector in the range is a mere 1.4mm yet power performance is not compromised by the small size, an impressive 2.5A (amps) maximum current rating per contact can be achieved using the 2 position connector with AWG 28 wire.

High reliability is guaranteed with HIROSE’s ’Swing Lock’ offering a unique double locking mechanism. 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 cannot be accidentally removed from the header. A small lever makes the unmating process very quick and easy. Durability is achieved with 30 mating cycles.

Swing-Lock Structure

Swing-Lock Structure

Blade contacts, renowned for their strength are utilised to prevent damage against any cable wrenching forces, these are positioned within a strengthened housing lance to increase the retention further. A long 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.
