Hirose releases 1.2mm pitch, wire to board connector series for power supplies
Hirose has launched the new DF57 series of headers, sockets and crimp contacts to meet with the demand for smaller yet better performing connectors.
The connector range has been designed with space saving in mind, the two position for example, only occupies 18mm²approximate board space. The height profile is a mere 1.4mm. Power performance is not compromised by the small size, an impressive 2.5 amp 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 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, 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.
The DF57 series is available in 2, 3, 4, 5 & 6 positions. These are suitable for AWG 28 or AWG 30 size cable size. These are ideal for LED displays, touch panels, small motors, industrial robots, LED lighting modules, digital cameras and many more devices needing more power.
