BL 2 22 G

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 2 22 G is a 22-position header connector designed for surface mount or through-hole applications with a 0.635 mm separable pitch. It features a stamped contact spring design and fork contacts. The connector operates within a temperature range of -40°C to 163°C, supports a maximum voltage rating of 125VAC, and has an insulation resistance of 1,000,000 MOhm.

Headers, Receptacles, Female Sockets Feature Summary

• Utilizes a stamped contact spring design for reliable electrical connection
• Incorporates fork contact geometry compatible with 0.635 mm separable pitch
• Constructed with gold-plated contacts to ensure corrosion resistance and low contact impedance

Headers, Receptacles, Female Sockets Applications

• Electronic assemblies requiring secure board-to-board interconnection
• Circuit boards utilizing standard 0.635 mm pin spacing
• Industrial control modules operating in high-temperature environments

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific mounting style (surface mount vs. through-hole) against the mechanical drawing, as product listings may vary by suffix. Confirm that the 0.635 mm pitch aligns with mating connector specifications. Ensure the 125VAC voltage rating meets the circuit requirements. Check for RoHS compliance if required by project standards.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a robust, fork-contact header is needed for 0.635 mm pitch systems. The gold plating offers superior durability compared to tin-only options. Consider the thermal stability up to 163°C for soldering processes or high-heat operation. Ensure the 22-position count matches the signal or power trace layout.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the BL 2 series from Fischer Elektronik, which specializes in connectors with precise 0.635 mm separable pitches. The series is characterized by its use of stamped contact springs and fork designs, providing a distinct alternative to standard square-pin headers. It is commonly used in applications demanding high reliability and specific mechanical engagement profiles.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must maintain the 0.635 mm pitch and fork contact design. Generic 0.100 inch (2.54 mm) headers are not interchangeable due to dimensional differences. Verify that any replacement part supports the same 125VAC rating and temperature range.
