The 053513-1270 is a D-Sub connector from the D*M series featuring 37 contacts (size 20) for high-reliability applications. It supports a wire gauge range of AWG 20-28 and is rated for a maximum current of 7.5 A with a contact resistance of 7.5 milli Ohm maximum. The connector operates reliably across a temperature range of -55°C to +125°C and provides a dielectric withstanding voltage of 1000 VAC at sea level, with a rated lifespan of 200 mating cycles. The steel shell with yellow finish and 20-hour salt spray test rating make it suitable for harsh environments, including aerospace, military, and industrial control systems where robust electrical connectivity and environmental resistance are essential.
