M83513/03-E03C is a Micro D metal shell connector plug designed for high-reliability applications requiring compact interconnection. It features 31 crimp contacts with gold-plated copper alloy material and a maximum contact resistance of 8 milliohms, housed in an aluminum shell with cadmium/yellow chromate finish over nickel. The connector includes 18-inch long pre-terminated wires (#26 AWG per MIL-W-22759/11-26) with color coding per MIL-STD-681, an LCP insulator, and supports a maximum current rating of 3 A with dielectric withstanding voltage of 600 VAC at sea level. The connector demonstrates robust environmental performance with thermal shock capability from -55°C to +125°C, physical shock resistance of 50 G's, vibration tolerance of 20 G's (10-2000 Hz for 12 hours), and durability rated for 500 mating/unmating cycles. This connector is ideal for aerospace, military, and industrial applications where reliable signal and power transmission in compact form factors is essential.
