FX30B Series, 3.81mm Pitch, 10A 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, vibration 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.
