BL 9 12

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 9 12 is a 12-position through-hole header connector designed for wire diameters between 0.635 mm and 0.85 mm. It features aligned Wire-Wrap contact pins with CuBe-alloy inner springs, Ni+0.75µm Au surface finish, and a 6-finger internal spring type. The protected contact insert prevents capillary action during soldering, ensuring separability.

Headers, Receptacles, Female Sockets Feature Summary

• Aligned Wire-Wrap contact pins ensure reliable connection for specified wire gauges
• Protected contact insert eliminates capillary action during the soldering process
• Separable design allows for flexible circuit point plugability

Headers, Receptacles, Female Sockets Applications

• Wire-to-board connections in electronic assemblies
• Circuit board headers requiring robust mechanical retention
• Applications involving wire diameters from 0.635 mm to 0.85 mm

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the required wire diameter falls within the 0.635 mm to 0.85 mm range to ensure proper contact engagement. Confirm that the application requires a through-hole mounting style compatible with standard PCB fabrication processes. Ensure the design accounts for the separated nature of the connector if disconnection is necessary post-soldering.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when specific wire gauge compatibility is critical for the assembly. The choice is driven by the need for aligned Wire-Wrap contacts and protection against solder wicking into the contact area. Consider the mechanical requirements for separability and the specific material properties of the CuBe-alloy springs for long-term reliability.
