Rectangular Connectors MCE Series Plastic Shell Edgeboard Connectors Plastic Shell Edge Board Connectors Designed for commercial applications requiring frequent disconnect and connect, including data recorders and computers. Mother board connector can be ordered to fit any pattern on your circuit board. Units are available with contacts as few as 40 and as many as 110. Wire sizes 28 through 24, any type of plating or color coding, any kind of wire termination including wire wrap -- a high degree of flexibility for your military or commercial application. Rectangular Connectors This new connector features the proven twist pin contact with precision contact alignment with extremely low engaging forces. 40 Contacts 2 Two hexagonal polarizing keys can provide up to 36 different key combinations are supplied. Technical & Performance Data -- Twist Pin Plastic Shell Connectors Electrical Contact Resistance -- The average mated contact resistance is 4 milliohms, with a maximum value of 8 milliohms, using standard 24 AWG 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 -- 800 VAC RMS at sea level (600 for solder pots); 200 VAC RMS at 70,000 feet [21,336m] (150 for solder pots). Corrosion Resistance (Per MILSTD-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. 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. Mechanical Contact Engaging & Separation Forces -- 8.0 oz. max. [2.24N] (eng.), 0.5 oz. min.[.14N] (sep.) Environmental Temperature Range (Operating) -- -67F to 257F [-55 C to +125C]. Vibration (Per MIL-STD-202C, Method 204A, Condition D) -- No discontinuity in excess of 1 sec. during twelve 20 minute sweeps from 10 to 2000 CPS at .06 double amplitude or 20 G forces, whichever is less. Materials Insulator -- Liquid Crystal Polymer (LCP) per ASTM D5138 or Polyphenylene Sulfide per MIL-M-24519. Contacts -- Pin-contact: Copper alloy and beryllium copper alloy make up the complete construction. Socket contact: Copper alloy. Hardware -- Corrosion resistant stainless steel. Finishes Insulator -- None. Contacts -- Standard finish is 0.000050 [0.00127] gold over copper flash per MIL-G-45204, Type II. Hardware -- Passivated per QQ-P-35. 39 Catalog 1308638 Revised 8-05 www.tycoelectronics.com Dimensions are in inches and millimeters unless otherwise specified.
