FEATURES
SMP20 SMS20
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.
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]. Minimum Air Space Between Contacts: .050" [1.27mm].
MATERIAL SPECIFICATIONS
Contact Pin: Brass, gold plated. Contact Socket: Phosphor bronze, gold plated. (Beryllium copper available on request.) Guides: Stainless steel, passivated. Screwlocks: Stainless steel, passivated. Standard Body: Glass-filled diallyl phthalate per MIL-M-14, Model GDI-30F, green.
