| Model SM20 Vishay Dale Rack and Panel Connectors Subminiature Rectangular SMP20 SMS20 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. 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. 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. PHYSICAL SPECIFICATIONS Number of Contacts: 5, 7, 11, 14, 20, 26, 34, 42, 50, 75. Contact Spacing: .120" [3.05mm]. Contact Gauge: #20 AWG. Minimum Creepage Path Between Contacts: .080" [2.03mm].
