SL 1 104 21 Z

Headers, Male Pins Overview

The SL 1 104 21 Z is a single-row male header connector manufactured by Fischer Elektronik. It features 21 positions with a 0.100-inch (2.54 mm) pitch. Designed for through-hole mounting, the contacts are constructed from copper-tin alloy and feature tin plating. The housing utilizes polyamide (PA46) insulation. Key dimensions include a total contact length of 0.441 inches (11.20 mm), a mating contact length of 0.213 inches (5.40 mm), and a pin length of 0.118 inches (3.00 mm). The square-shaped pins have a mating surface thickness of 157.5 µin (4.00 µm).
