BL 2 4 Z

Headers, Receptacles, Female Sockets Overview

The Fischer Elektronik BL 2 4 Z is a PCB header connector designed for through-hole mounting. It features a dual-row configuration with four positions, providing reliable electrical connectivity in compact assemblies. The component utilizes a stamped contact spring mechanism with a fork contact design, engineered specifically for a separable pitch of 0.635 mm. Constructed with copper tin alloy contacts, the unit ensures stable signal transmission. The contacts are finished with a tin-plated surface to enhance corrosion resistance and solderability. This connector is suitable for applications requiring secure board-to-board or wire-to-board connections within dense electronic layouts.

• Tin-plated copper tin alloy contacts for enhanced durability

Headers, Receptacles, Female Sockets Applications

• Compact PCB interconnects
• Board-to-board signal routing
• Wire-to-board connections

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix and packaging format directly with the manufacturer or authorized distributors. Confirm that the 0.635 mm pitch requirement aligns with your PCB footprint design. Ensure compatibility with standard through-hole assembly processes. Check for any specific RoHS compliance documentation if required by your regulatory standards. Validate the contact material specifications against your environmental operating conditions.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, dual-row header is required for tight spacing constraints. The 0.635 mm pitch allows for higher density compared to standard 2.54 mm headers. Consider the tin-plated finish for general-purpose environments where gold plating is not strictly necessary. Evaluate the mechanical stability provided by the stamped spring contact design for vibration-resistant applications. Ensure the through-hole mounting method fits your manufacturing capabilities.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Fischer Elektronik BL 2 series, which specializes in high-density interconnect solutions. The series is characterized by its use of stamped contact springs rather than formed wires, offering cost-effective mass production benefits. The BL 2 4 Z represents a specific pin count variant within this family, maintaining consistent mechanical and electrical characteristics across different position options.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 0.635 mm pitch, dual-row configuration, and through-hole mounting style. Verify that alternative components offer identical fork contact geometry to ensure mating compatibility. Cross-reference the contact material and plating thickness to maintain equivalent performance under similar thermal and mechanical stresses.
