ELECTRICAL SPECIFICATIONS
Current Rating: 7.5 amps. Breakdown Voltage: At sea level: 2000 V RMS. At 70,000 feet [21,336 meters]: 500 V RMS.
• 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.
