WTB54PR9SY-2

Overview

The AirBorn WTB54PR9SY-2 is a rectangular board mount plug connector from the W Series, designed for high-reliability applications. It features 54 positions arranged in two rows with a 2.54 mm (0.100 inch) contact pitch. The component utilizes male pin contacts made of copper alloy with gold plating, terminated via through-hole soldering. Constructed with a Polyphenylene Sulfide (PPS) housing, it operates within a temperature range of -65°C to +125°C and supports up to 5 A current per contact.
