M20-9741742

Headers, Male Pins Overview

The M20-9741742 is a male pin header from the Harwin M20 series, designed for through-hole mounting with a right-angle orientation. It features a 34-position configuration arranged in two rows, utilizing a 0.100 inch (2.54mm) pitch. The connector system supports board-to-board or cable applications. Contact plating consists of gold over tin to ensure reliable conductivity and corrosion resistance. The housing is constructed from polyamide, offering mechanical stability within an operating temperature range of -40°C to 105°C.
