BL 5 18

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 5 18 is an 18-position female header connector designed for through-hole PCB mounting. It features a straight configuration with a 2.54 mm (0.100 inch) pitch. The contact system utilizes inner spring contacts plated with gold (≥0.75 µm) to ensure reliable signal transmission, while the contact sleeves are tin-plated. This component belongs to the BL 5 series, which is engineered for precision and reliability in electronic assemblies requiring robust mechanical and electrical connections.

Headers, Receptacles, Female Sockets Feature Summary

• Straight female header design for direct through-hole PCB integration
• Inner spring contact technology with gold plating for enhanced conductivity
• Tin-plated contact sleeves providing corrosion resistance
• Standardized 2.54 mm pitch ensuring compatibility with industry-standard mating pins

Headers, Receptacles, Female Sockets Applications

• Precision electronic assembly interconnections
• Through-hole PCB connection systems
• Reliable signal transmission in industrial electronics

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Fischer Elektronik datasheet to confirm exact plating thickness and contact material specifications. Ensure the selected variant matches the required current rating and voltage parameters for the target application. Cross-reference the part number with the manufacturer's latest documentation to avoid discrepancies in pin count or housing dimensions.

Headers, Receptacles, Female Sockets Selection Notes

Select this connector when a straight, through-hole female header with high-reliability spring contacts is required. The 2.54 mm pitch ensures broad compatibility with standard male headers. Consider the gold-plated inner contacts for applications demanding low contact resistance and long-term stability. Verify that the tin-plated sleeves meet environmental requirements for the operating environment.

Headers, Receptacles, Female Sockets Part Context

The BL 5 series represents Fischer Elektronik's range of female headers for PCB connections. These connectors are characterized by their use of internal spring contacts rather than traditional press-fit mechanisms, offering consistent contact force. The BL 5 18 specifically provides an 18-pin configuration, fitting within the broader family of connectors designed for dense, reliable board-to-board or cable-to-board interfaces.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 18-position count, 2.54 mm pitch, and through-hole mounting style. Verify that alternative components offer comparable spring-contact mechanics and similar plating specifications to maintain electrical performance. Generic equivalents may lack the specific gold-plated inner contact feature, potentially affecting long-term reliability.
