BL 2 40 G

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 2 40 G is a 40-position female header connector designed for through-hole mounting on printed circuit boards. It features a 2x20 contact arrangement with a 2.54 mm (0.100 inch) grid spacing and a 2-row configuration. The contacts are gold-plated to ensure reliable signal transmission. This component utilizes a stamped contact spring design with a fork contact structure, engineered for a 0.635 mm separable pitch. The connector supports solder termination and operates within a temperature range of -40°C to +200°C.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific part number BL 2 40 G against official Fischer Elektronik documentation to confirm pin count, row configuration, and plating specifications. Ensure compatibility with mating male pins of 0.635 mm diameter. Check datasheet for thermal resistance and current rating requirements before integration into final designs.

Headers, Receptacles, Female Sockets Selection Notes

Select this connector when a 40-position, 2-row female header with 2.54 mm pitch is required for through-hole applications. The gold plating offers superior corrosion resistance compared to tin variants. Consider the fork contact geometry for specific mating force requirements. Verify that the operating temperature range of -40°C to +200°C meets environmental constraints.

Headers, Receptacles, Female Sockets Part Context

The BL 2 series represents Fischer Elektronik's standard line of female headers featuring stamped contact technology. These connectors are characterized by their modular design, allowing for various contact counts while maintaining consistent mechanical dimensions. The BL 2 40 G specifically provides a high-density solution for vertical board connections within this established product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 2x20 pin count, 2.54 mm pitch, and through-hole mounting style. Verify that alternative components support the same 0.635 mm separable pitch and offer comparable gold plating thickness. Cross-reference mechanical drawings to ensure housing dimensions and terminal spacing align with existing PCB footprints.
