FX22 Series, 0.5mm Pitch, Floating, Board-to-Board Connectors with Double Beam Contacts

The FX22 series has been introduced to meet the requirement for floating connectors that can absorb mounting misalignment in applications where multiple stacking connectors are used.


The connector range consists of low profile headers and receptacles that allow a coplanar board-to-board connection. The header connector has a unique floating structure embedded inside the housing. This allows an alignment movement in XZ directions of +/- 0.6mm maximum to absorb mounting misalignment to reduce mounting failure. Large mating guides on each side of the connector allow for an alignment movement of +/-1.2mm in XZ directions to simplify the mating operation and prevent incorrect insertion.

The receptacle features double beam contacts. Each beam is designed with a different contact force to ensure dissimilar vibration characteristics and different resonant frequencies to minimise damage between the contacts and achieve high vibration resistance. Furthermore the first beam contact has a self-cleaning function which eliminates dust from the contact path of the second beam contact to increase contact reliability.

Due to the floating function of FX22, the popular high speed FX18 series, board-to-board connectors can be combined on the same board. this allows the opportunity to add a high-speed connectivity solution to the design. in addition, the FX20 series can be combined to provide a vertical or parallel connection.

FX22 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.
