Amphenol M55302 172 01 bristle brush contact offering smooth interface and redundant current paths for connectivity
Amphenol Bristle Brush Contact Technology
Product Overview
The Amphenol Bristle Brush Contact is a high-density interconnect solution designed for superior electrical connections with low mating forces. Utilizing multiple strands of high-tensile strength wires bundled together, it provides redundant current paths and a gas-tight junction with 14-70 points of contact per mated connection. Proven in military avionics and meeting MIL-DTL-55302 requirements, this technology offers high density in tighter spacing, low mating/unmating forces, and long contact life, making it ideal for demanding applications in medical equipment, telecommunications, aviation, and military ground vehicles.
Key Advantages:
- Superior electrical connection with low mating force.
- High density in tighter spacing.
- Proven durability and long contact life (up to 100,000 mating cycles).
- Stable, low resistance (20 milliohms max.).
- Redundant current paths for reliable connections.
- Smooth, low friction interface.
- 70% to 90% reduction in mating/unmating forces compared to conventional pin-socket contacts.
Applications:
- Medical equipment
- IC chip testers
- Telecommunications
- Military and Commercial Aviation
- Military Ground Vehicles
- GPS systems
