RM252-080-311-5500

Headers, Male Pins Overview

The RM252-080-311-5500 is a rectangular MIL-DTL-55302 series connector manufactured by AirBorn, a Molex company. It is a right-angle board mount plug featuring a plastic body and dual row configuration with 80 positions. The component utilizes a 1.91 mm pitch and through-hole termination for secure PCB integration. Contacts are gold-plated beryllium copper pins designed for reliable signal transmission. The housing is constructed from Polyphenylene Sulfide (PPS), supporting an operating temperature range of -65°C to +125°C. Rated at 750 V and 3 A, this connector ensures high insulation resistance of 5 GOhms in demanding military and aerospace applications.
