| Performance Environ./Elect. |
Markets |
Operating temp. from –65°C to +125°C. Connector bodies are high performance glass-filled thermoplastic moldings.
Connector configurations are capable of supporting data rates up to 400 Mbps. Bristle Brush contacts provide:
- Low mating/unmating forces - 70% to 90% reduction from conventional pin and socket contacts.
- Proven durability and long contact life - over 20,000 cycles of mating and unmating without performance degradation.
- Multiple points (14-17) of contact per mated contact.
- Intermittency-free performance.
- Redundant current paths (stable, low resistance).
- Proven electrical and gas tight contact sites.
