The Amphenol Bristle Brush Contact technology, featured in their Low Mating Force Rectangular Connectors, utilizes multiple strands of high tensile strength wires bundled together to create a superior electrical connection with exceptionally low mating forces. Proven in demanding applications such as military avionics and meeting MIL-DTL-55302 requirements, these connectors offer high density in tighter spacing, exceptional durability, and long contact life. They are ideal for applications requiring frequent mating and unmating, such as medical equipment, IC chip testers, telecommunications, military and commercial aviation, military ground vehicles, and GPS systems. The unique brush contact design provides redundant current paths, ensuring a gas-tight junction with 14-70 points of contact per mated pair, leading to stable, low resistance electrical connections.
