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.
