This type of connector is fed through and secured from the front of a device or panel, serving to transmit signals from internal circuitry through a panel. This widely used design features a flange with four holes, allowing for attachment via screws or bolts. The additional two holes provide stronger mounting compared to 2-hole flange designs, offering improved mechanical stability and resilience, particularly against torsional forces. This attribute is particularly beneficial in high-vibration environments or applications where robustness is crucial.
