FEATURES
• Lightweight
Polarized by guides or screwlocks
Screwlocks lock connectors together to withstand vibration
and accidental disconnect
Overall height kept to a minimum
• Floating contacts aid in alignment and in withstanding
vibration
Contacts, precision machined and individually gauged,
provide high reliability
Insertion and withdrawal forces kept low without increasing
contact resistance
Contact plating provides protection against corrosion,
assures low contact resistance and ease of soldering
APPLICATIONS
For use wherever space is at a premium and a high quality
connector is required in avionics, automation,
communications, controls, instrumentation, missiles,
computers and guidance systems.
