M83513/03-D03C is a Micro-D metal-shell microminiature connector conforming to MIL-DTL-83513 specifications, featuring a polarized D configuration with 0.050" contact spacing. The connector utilizes ITT Cannon's proprietary Twist Pin Contact System, which provides highly reliable continuity in dense areas under severe shock and vibration conditions while requiring low engagement and separation forces. It supports 36" long #26 AWG wires with color coding per MIL-STD-681 System 1 (10-color repeating pattern), accommodates up to 21 contacts in a compact form factor, and is rated for 3A maximum current with 8 milliohms maximum contact resistance. The aluminum shell with yellow chromate/cadmium over nickel finish meets demanding aerospace, defense, and industrial applications requiring robust, lightweight interconnect solutions in harsh environments.
