The FX30B from Hirose is a series of board-to-board connectors with high current capacity of 17A, and the ability to absorb mating tolerances in assemblies using multiple connectors.

The connector features a special innovative contact structure which allows movement of up to ±0.3mm in the x, y directions and +1mm in the z direction to absorb mating misalignment and dimensional errors. This is possible because the blade contacts on the header and the unique spring contacts on the receptacle are staggered to maintain a sufficient deflection range in the limited space.

In addition, the gold-plated contacts feature four independent angled contact points, for secure mating. The effective mating length of 2mm also provides for high contact reliability.

The moulded guide posts on the header engage with the ribs on the receptacle to allow for a mating alignment movement, simplifying the mating operation and preventing incorrect insertion. In addition, there are six keys around the mating face which prevent reverse insertion.

The FX30B is available in three variants to provide for vertical, parallel or co-planar board-to-board connections.
