BL 20 SMD 28 SM

Headers, Receptacles, Female Sockets Overview

The BL 20 SMD 28 SM is a surface-mount male header connector manufactured by Fischer Elektronik. It features 28 positions with a standard 0.100-inch (2.54mm) pitch. The contacts are gold-plated to ensure reliable signal transmission and corrosion resistance. Designed for PCB integration, this component accommodates pin diameters ranging from 0.635 mm to 0.85 mm, providing secure mechanical retention for mating cables or boards.

Headers, Receptacles, Female Sockets Feature Summary

• Gold-plated contact surfaces for enhanced conductivity
• Surface-mount technology design for automated assembly
• Standard 2.54mm pitch for broad compatibility

Headers, Receptacles, Female Sockets Applications

• PCB-to-PCB interconnections
