BL 3 20 Z

Headers, Receptacles, Female Sockets Overview

The BL 3 20 Z is a stamped contact spring header manufactured by Fischer Elektronik. It features a forked contact type with 20 positions arranged in a single row. The connector utilizes a separable pitch of 0.635 mm, allowing for flexible configuration to accommodate various circuit board layouts. Designed for through-hole mounting, it operates within a temperature range of -40°C to 200°C. The unit meets UL94 V-0 material flammability ratings and supports a nominal current of 3 A at 125 V AC.

Headers, Receptacles, Female Sockets Feature Summary

• Stamped contact spring design with forked contacts for secure mating
• Separable pitch of 0.635 mm enables flexible configuration options
• High operating temperature tolerance up to 200°C
• UL94 V-0 rated insulation material for safety compliance

Headers, Receptacles, Female Sockets Applications

• Flexible wiring harness connections requiring variable spacing
• High-temperature electronic assemblies
• Custom PCB interconnect solutions needing adaptable pin counts
• Industrial control modules with strict thermal requirements

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'Z' against official Fischer Elektronik documentation to confirm plating or packaging variations. Ensure the required separable pitch configuration matches your PCB layout constraints. Cross-reference the 0.635 mm pitch specification with mating components to guarantee mechanical compatibility. Confirm that the 3 A current rating aligns with your application's electrical load requirements before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a standard fixed-pitch header is insufficient for your design. The 0.635 mm separable pitch allows you to adjust the number of active pins while maintaining consistent spacing. Consider the high-temperature rating if the assembly environment exceeds standard industrial limits. Verify that the forked contact geometry is compatible with your mating plug or wire termination method to ensure reliable electrical connection.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL 3 series of stamped contact springs from Fischer Elektronik. The series is characterized by its modular nature, allowing users to configure the exact number of positions needed. The BL 3 20 Z specifically provides twenty forked contacts. This modularity distinguishes it from rigid, pre-formed headers, offering greater adaptability for custom electronic designs where space or pin count may vary.

Headers, Receptacles, Female Sockets Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the specific forked contact geometry and 0.635 mm separable pitch, generic headers are not direct replacements. Consult Fischer Elektronik directly for equivalent series parts or updated model numbers if this specific variant is discontinued.
