Microminiature D Connectors MCDM Series Metal Shell Connectors Performance Contact Resistance -- The average mated contact resistance is 4 milliohms, with a maximum value of 8 milliohms, using standard #24 solid copper leads when measured directly behind the crimp joints of the mated pin and socket contacts. The average resistance value at 100 microvolts is 4.8 milliohms. Dielectric Withstanding Voltage (60 Hz rms room temperature) -- Solder Pots: 600 VAC at sea level; 150 VAC at 70,000 feet [21,336 m]. Wire Terminations: 750 VAC at sea level; 200 VAC at 70,000 feet [21,336m] Vibration (Per MIL-STD-202C, Method 204-A, Condition D) -- No discontinuity in excess of 1 microsecond during twelve 20 minute sweeps from 10 to 2,000 CPS at .06 double amplitude or 20 G forces, whichever is less. Corrosion Resistance (Per MIL-STD-202C, Method 101B, Condition B) -- Both mated and unmated samples do not exceed the maximum allowable contact resistance (8 milliohms) when subjected to the 48 hour salt spray test. Durability -- The contact resistance after 500 mating cycles is less than the maximum allowable, 8 milliohms. Insulation Resistance -- Greater than 5,000 megohms at room temperature for the materials listed under "Materials". Maximum Current Carrying Capacity -- No. 24 contact, 3 amperes. It must be recognized, however, that all the wires to a connector will not carry their maximum current under all environmental conditions due to wire temperature. Contact Engaging and Separation Forces -- 6 oz. [1.67N] maximum (eng.); 0.5 oz. [.14N] minimum (sep.). Temperature Range (Operating) -- Diallyl phthalate -67F to 257F [-55C to +125C]. Microminiature D Connectors Technical & Performance Data Materials Insulator -- Diallyl phthalate per MIL-M-14, Type SDG-F or Liquid Crystal Polymer (LCP) per ASTM D5138. Contacts -- Pin Contact: Copper alloy and beryllium copper alloy make up the complete construction. Socket Contact: Copper alloy. Body Shell -- High grade aluminum alloy. 1 Finishes Contacts -- Standard finish is 0.000050 [0.00127] gold over copper flash per MIL-G-45204, Type II. Body Shell -- Electroless nickel per AMS 2404. Note: Insulators are molded into their metal shells -- No bonded joint is used. Screw Mount A F Contact #1 E .193 [4.90] .089-.094 Dia. [2.26-2.39] 2 Plcs. Pin B .093 [2.36] The only metal shell connector that mates with all existing plastic types. This line is ideal for external use and other applications requiring frequent disconnect and remating. When durability and reliability are paramount the metal shell connector is unsurpassed -- it eliminates the need for retrofitting where new metal shell varieties must mate with older plastic types. Originally designed for military applications, they are currently used for commercial requirements, including computers. .379 [9.63] Pin Pin D C A F Contact #1 E .180 [4.57] .089-.094 Dia.
