BL 2 50 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 2 50 Z is a PCB receptacle connector designed for through-hole mounting. It features a two-row configuration with 50 contacts, utilizing a 2.54 mm pitch. The nominal voltage rating is 125 V AC, supported by a test voltage of 1500 V. The insulating body is constructed from PPS material, ensuring stability across a temperature range of -40°C to +200°C. The component complies with UL 94 flammability standards and withstands soldering temperatures up to 260°C for 10 seconds.

Headers, Receptacles, Female Sockets Feature Summary

• Fork contact design engineered for a 0.635 mm separable pitch
• Stamped contact spring construction allows for cutting to length
• Tin-plated surface finish over nickel base layer ensures conductivity

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnections
• Through-hole PCB mounting systems
• Industrial electronic assemblies requiring high-temperature resistance

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific pin count and row configuration against the datasheet before ordering. Confirm that the 2.54 mm pitch aligns with the target PCB layout. Ensure the operating environment remains within the specified -40°C to +200°C thermal limits. Check compatibility with standard reflow or wave soldering processes at 260°C. Validate that the fork contact design meets mechanical retention requirements.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 50-position, two-row connector is required for rigid board connections. The stamped spring design offers flexibility in customizing contact lengths. Consider the PPS insulation for applications demanding high thermal endurance. The tin plating provides cost-effective conductivity suitable for general industrial use rather than harsh corrosive environments.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Fischer Elektronik BL series of female headers and connectors. The series includes various configurations for board-to-board and cable connections. The BL 2 variant specifically utilizes a fork contact design optimized for precise separable pitches. This product line supports both straight and right-angle mounting options for diverse PCB architectures.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 50-pin, two-row, 2.54 mm pitch specification. Verify that alternative components support the same 125 V AC rating and 1500 V test voltage. Ensure replacement parts utilize compatible PPS insulation and meet UL 94 standards. Confirm that the fork contact geometry and stamped spring mechanism are functionally equivalent.
