Hirose FX30B series, 3.81mm / 7.62mm pitch, up to 17A power, board to board connector with misalignment absorption structure

The FX30B series has been introduced to meet the requirement for board to board connectors with high current capacity and the ability to absorb mating tolerances where multiple connectors are used.

The connector range features a special innovative contact structure that allows movement in XY directions of up to +/- 0.3mm and + 1mm in Z direction to absorb mating misalignment and dimensional errors. This is achieved by the blade contacts on the header and the unique spring contacts on the receptacle that are staggered to maintain sufficient deflection range in the limited space. In addition, the gold plated contacts feature four independent angled contact points that guarantees advantageous contact.

The effective mating length of 2mm also contributes to ensuring high contact reliability. The moulded guide posts on the header engage with the ribs on the receptacle to allow for a mating alignment movement of +/- 1.3mm in XY directions to simplify the mating operation and prevent incorrect insertion. In addition, there are six keys around the mating face that further prevent reverse insertion.

Three different variations are available to allow a vertical, parallel or coplanar board to board connection. Hirose's popular FX18 high speed connector can be used on the same board as FX30B to offer a flexible, high speed and high current capability.

FX30B series is part of the FunctionMAX product family. FunctionMAX consists of board-to-board connectors designed to meet the requirements of the industrial market with maximum functionality.
