What is a floating connector?

A floating connector is a board-to-board electromechanical interconnect for data and/or power that absorbs misalignments and small movements in multiple axes. Unlike traditional connectors, floating connectors features a spring-like mechanism to provide elasticity and take the stress off both the solder joints and contact pins.

  • Benefits of Floating Connectors

    Enhanced manufacturing productivity and quality

    Growth of automated manufacturing demands solutions for the high-speed placement of board-to-board connectors. However, when you have connectors mating the same two PCBs, the tolerance of the product location (whether from PCB manufacture, paste location, pick and place accuracy or a combination of these) can mean that one or both connectors will encounter additional side-loading and risk of damage that can halt production or lead to quality issues.

    Their ability to handle slight movements allows floating connectors to compensate for accumulative positional mis-alignment across multiple board-to-board connectors. This not only makes for easier mating but also gives designers the flexibility to populate PCBs with two or more connectors without worrying about precise positional accuracy or compromising automated assembly throughput.

    Industrial Automation
    Improved reliability, extended operational life

    As well as aiding alignment, the positional freedom of floating connectors eases any mechanical stresses that occur should one or more connections be mis-aligned. This extends operational life by mitigating against the possibility of long-term defects, including solder cracking.At the same time, the spring-based ‘suspension’ mechanism improves in-field reliability by helping to maintain contact force during operational life.



    Incorporating pins that are formed with a bend that flexes and housings that are suspended by the pins, floating connectors incorporate a spring-like action in the interior and exterior insulators. This allows the connectors to support positional tolerances across multiple axes – ‘floating’ between rows and in the direction of pitch.
