BL 9 35

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 9 35 is a PCB receptacle from the BL 9 series, featuring a 2.54 mm pitch spacing and 35 contacts. It utilizes gold-plated wire-wrap contact pins designed for wire diameters between 0.635 mm and 0.85 mm. The component operates within a temperature range of -40°C to +163°C and withstands soldering conditions at 260°C for 10 seconds. It meets UL 94 V-0 flammability standards and offers specific insulation resistance properties.

Headers, Receptacles, Female Sockets Feature Summary

• Gold-plated contacts ensure reliable electrical connections
• Aligned wire-wrap pins accommodate specified wire diameters
• High thermal stability supports standard soldering processes

Headers, Receptacles, Female Sockets Applications

• General-purpose printed circuit board interconnections
• Prototyping and development boards requiring wire-wrap termination
• Industrial control modules with strict flammability requirements

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the required wire diameter falls within the 0.635 mm to 0.85 mm range for proper pin engagement. Confirm that the application environment remains within the -40°C to +163°C operating limits. Ensure compatibility with standard wire-wrap tools and check that the 35-contact configuration matches the design footprint. Review UL 94 V-0 certification if flame retardancy is critical for the assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-density 35-position connection is needed on a PCB with a 2.54 mm grid. It is suitable for applications requiring gold plating for corrosion resistance and low contact resistance. Consider the wire-wrap termination method as it eliminates the need for crimping or soldering individual wires to the connector body. Evaluate space constraints against the physical dimensions of the BL 9 series housing.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL 9 series of PCB receptacles. The series provides various contact counts and configurations for board-to-wire connections. The BL 9 35 specifically denotes the 35-contact variant with aligned wire-wrap pins. It is distinct from other Fischer series like SL 4 or BL 1, which may differ in mounting style or contact type.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 2.54 mm pitch, 35 contacts, and wire-wrap pin style. Verify identical housing dimensions and terminal orientation. Cross-reference with other manufacturers' wire-wrap headers if availability is an issue, ensuring material and plating specifications align.
