MDM-25PH074M5 is a Micro-D metal shell connector designed for high-reliability interconnect applications in aerospace, defense, and industrial systems. This 25-pin connector features a pin contact configuration with harness-insulated wire termination, electroless nickel plating per QQ-N-290, and a keystone-shaped shell for positive polarization. The connector operates at 100 VDC working voltage with a maximum current rating of 3 amps and dielectric withstanding voltage of 300 VAC, supported by an insulation resistance of 5000 MO at 100 VDC. With a contact spacing of 0.050 inches (1.27 mm) and friction/jackscrew coupling, this connector provides robust mechanical and electrical performance for demanding applications requiring miniaturized, reliable signal and power interconnections.
