BL 2 20 G

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 2 20 G is a 20-position socket header connector designed for through-hole mounting. It features a fork contact design with a 0.100 inch (2.54 mm) pitch and operates within a temperature range of -40°C to 163°C. The contacts are gold-plated with a thickness of 7.87 µin (0.20 µm), while the column plating is tin, measuring 157.5 µin (4.00 µm). Rated at 125VAC and 3A, it utilizes black polyamide insulation compliant with UL94 V-0 flammability standards.
