Smarter, faster and smaller: Amphenols 2M the only connector youll ever need. 2M803 Features Bayonet Coupling Quickest turn-mating of the 2M series 1,000 mating cycles Lightest of the 2M series Why 2M803 2M803 connectors are very light and their fast, sure-mate bayonet coupling make them the perfect choice for light duty applications that require frequent disconnect. Their small size and easy decoupling also make them the connector of choice for customers who have hard-to-reach panels. Unlike their other 2M counterparts, 2M803 connectors are not rated for immersion, and are recommended for general purpose connections that will not be exposed to the elements for very long. 2M803 VS 38999 SPECIFICATION 2M803 MIL-DTL-38999 SERIES II Signal Count 1 to 55 1 to 187 Insulation Resistance 5,000 megaohms min 5,000 megaohms min Operating Temperature -65C to +150C -65C to +175C Shock 300 G 15 300 G 15 Vibration37.0 G Random N/A 30.0 G Sin Shielding Effectiveness40 dB min. from 45 dB min. from 100 MHz to 1000 MH 100 MHz to 1000 MH Durability 2,000 mating cycles min. 500 mating cycles Shell to Shell Conductivity 100 mV drop max 200 mV drop max Contacts Per AS39029 Per AS39029 2M803 MATERIALS AND FINISHES Shells Aluminum Alloy or Stainless Steel Contacts Copper Alloy, gold plated Insulators Polyphenylene Sulfide (PPS) Contact Retention Beryllium Copper Alloy Grommet, Interfacial Seal, O-Ring Fluorosilicone Rubber E 58 Contact Amphenol Aerospace for more information at 800-678-0141 www.amphenol-aerospace.com Contact Amphenol Aerospace for more information at 800-678-0141 www.amphenol-aerospace.com 2M803 2M8032M803 E E E E E E E l l l l l l l U U U U U U U o o o o o o o / / / / / / / n n n n n n n 2 2 2 2 2 2 2 0 0 0 0 0 0 0 e e e e e e e 0 0 0 0 0 0 0 h 2 h 2 h 2 h 2 h 2 h 2 h 2 2M803 1/4 Turn Bayonet Coupling Ordering Guide for 2M803 Crimp Receptacles & Plugs Micro38999 1. 2. 3. 4. 5. 6.
