BL 4 40 G

Headers, Receptacles, Female Sockets Overview

The BL 4 40 G is a female header connector manufactured by Fischer Elektronik. It features a 40-position configuration arranged in a dual-row format with a 2x20 pin layout. The connector utilizes a 2.54 mm (0.100 inch) pitch and is designed for through-hole mounting on printed circuit boards. The contacts are gold-plated to ensure reliable electrical performance, and the housing is black. The unit is angled at 90 degrees, facilitating specific board orientation requirements.

Headers, Receptacles, Female Sockets Feature Summary

• Angled 90-degree design for space-efficient PCB integration
• Gold-plated contacts for corrosion resistance and conductivity
• Through-hole termination method for secure mechanical attachment

Headers, Receptacles, Female Sockets Applications

• General-purpose PCB interconnections
• Board-to-board stacking applications
• Electronic equipment signal routing

Headers, Receptacles, Female Sockets Procurement Notes

Verify the exact part number against manufacturer documentation to confirm the 90-degree angle specification and gold plating thickness. Ensure compatibility with mating male headers regarding pitch and row spacing. Check for RoHS compliance status if required by project specifications before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a right-angle female header is required for dense circuit layouts. The 2.54 mm pitch ensures compatibility with standard breadboard and prototyping systems. Consider the physical height and clearance requirements of the angled design relative to surrounding components on the target assembly.

Headers, Receptacles, Female Sockets Part Context

This part belongs to Fischer Elektronik's BL series of socket headers. The series provides various pole counts and configurations for electronic assemblies. The BL 4 40 G specifically addresses the need for a 40-pin interface in a compact, angled form factor suitable for industrial and consumer electronics manufacturing.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes must match the 2x20 pin count, 2.54 mm pitch, and 90-degree angle. Verify that alternative manufacturers offer equivalent gold contact plating and through-hole termination capabilities to maintain mechanical and electrical integrity within the existing design constraints.
