RM412-250-521-9501

Headers, Male Pins Overview

The AirBorn RM412-250-521-9501 is a rectangular MIL-DTL-55302 series connector designed for board mount applications. It features a plastic body with four rows and a 1.91 mm pitch, providing 250 positions. The plug utilizes male pin contacts made of beryllium copper and brass, finished with gold plating. Termination is achieved via scored surface mount (SMD/SMT) technology with a 0.014-inch tail length. The unit operates within a temperature range of -65°C to +125°C, carries a 3 A current rating, and includes polarized guide pins.
