WTB44PR9J

Headers, Male Pins Overview

The WTB44PR9J is a rectangular military specification connector from the AirBorn W Series, manufactured by Molex. This right-angle plug features 44 positions arranged in a dual-row configuration with a 2.54mm (0.100 inch) contact pitch. Designed for board-to-board mounting, it utilizes pin contacts and through-hole solder terminals with a 0.140-inch tail length. The housing is constructed from polyphenylene sulfide (PPS), and the copper alloy contacts provide a current rating of 5 amperes.
