SL 1 104 21 G

Headers, Male Pins Overview

The SL 1 104 21 G is a single-row male pin header manufactured by Fischer Elektronik. It features a 2.54 mm (0.100 inch) pitch and contains 21 contacts. The connector utilizes through-hole straight mounting for PCB integration. Contact materials consist of copper tin, with gold plating on the post surfaces to ensure reliable conductivity. The insulation material is polyamide (PA46), specifically glass-filled nylon, providing structural stability. This component is designed for board-to-board or wire-to-board interconnections in electronic assemblies.
