Brush Contact Advantages
- Low Mating &
Unmating Forces:- Smooth,
low friction interfaces - 70-90% reduction in mating/
unmating forces from conventional pin-socket contacts - 1.5oz Maximum forces per contact pair (1oz typical)
- Easy mating/
unmating makes high circuit counts practical (25 lbs typical for 400 contacts) - Mechanical mating aids not required
- No need for external board support structures for connectors up to 7in. long.
- Smooth,
- Proven Durability and Long Contact Life
- 100,000 mating cycles, even when hot swapped
- Documented intermittency free performance - no 10nano second discontinuities during 50m cycles of 0.010 displacement
- 14-70 points of contact per mated contact
- Stable, low resistance - 20 mΩ max.
- Redundant current paths result in lower total resistance
- Proven electrical and gas tight contact sites
-
Multiple Points of Contact Provide Superior electrical Capability
