Hirose Electric has introduced the DF63 series of small, high-powered wire-to-board connectors for use in industrial equipment which must achieve high levels of reliability.

The main connector range consists of cable-mount female crimp sockets and board-mount vertical and right angle male headers. The connectors can handle a maximum current of 15A. Hirose also supplies in-line versions of the connector, and a waterproof DF63W series.

The connectors’ form factor enables the designer to achieve space savings. The three-position header only occupies board space of 88mm² due to its small pitch.

Secure locking is assured by a robust lock which gives a clear tactile click when mated. This confirms the connector is fully engaged.

The lock is on the centre of the housing, eliminating the risks of uneven locking and cable entanglement, which are common with side locks. This also enables multiple connectors to be mounted close together when side-by-side.

The header features square male pin contacts which have a wide conductive surface area of 1.14mm on each side to carry high currents. Each contact is protected by housing walls to prevent them from short-circuits and from being touched.

The cable-mount female socket housing uses crimp contacts which have an internal multipoint contact structure to ensure good contact wipe and high contact reliability. The design of the housing base is tapered to allow resin sealing up to 5mm high. The resin stopper, which is a step underneath the lock, stops the resin rising too far.
