LTMM-103-02-S-D-RA

Headers, Male Pins Overview

LTMM-103-02-S-D-RA is a board-to-board header from the Flex Stack LTMM series. It features a 2.00 mm (0.079 inch) mating pitch and a 2.00 mm row spacing. The connector provides 6 positions across two rows with all pins loaded. It utilizes male pin contacts made of phosphor bronze, finished with gold over nickel on the mating interface and tin over nickel on the termination column. Designed for surface mount installation in a right-angle orientation, it offers a mating contact length of 2.54 mm and a column length of 2.29 mm. The housing is constructed from black liquid crystal polymer (LCP), ensuring reliable performance within an operating temperature range of -55°C to 125°C.
