1-1437274-8

Overview

The TE Connectivity AMP Connectors 1-1437274-8 is a dual female card edge connector featuring 56 positions with a 0.125-inch (3.18mm) pitch. Designed for through-hole mounting, it utilizes gold-plated phosphor bronze contacts to ensure reliable signal transmission. The housing is constructed from black thermoplastic material, providing structural integrity and insulation. This component supports high-density interconnect applications requiring robust mechanical stability and consistent electrical performance across multiple circuit paths.

Feature Summary

• Dual female contact configuration for secure board interface
• Gold-plated contacts for enhanced conductivity and corrosion resistance
• Through-hole mounting for stable PCB integration

Applications

• High-density electronic assemblies
• Industrial control systems
• Telecommunications equipment

Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing material variations. Ensure compatibility with target PCB edge thickness specifications before procurement. Confirm RoHS compliance status if required by project standards. Cross-reference the manufacturer datasheet for precise mechanical dimensions and mating force requirements to prevent assembly issues.

Selection Notes

Select this connector when a 56-position dual-edge interface is required. Verify that the target printed circuit board edge thickness falls within the specified operational range. Ensure the application environment does not exceed the thermal ratings of the thermoplastic housing. Confirm that the 0.125-inch pitch aligns with the system's density requirements and mating constraints.

Part Context

This component belongs to the standard card edge connector family manufactured by TE Connectivity AMP Connectors. It serves as a critical interconnect solution for rigid-to-rigid board connections. The design emphasizes reliability in demanding environments through durable materials and precise manufacturing tolerances. It complements other connectors in the series offering various position counts and mounting styles.

Replacement Considerations

Direct substitutes must match the 56-position count, dual female configuration, and 0.125-inch pitch. Verify identical mounting style and housing color if aesthetic or mechanical constraints exist. Consult manufacturer cross-reference lists for verified alternative part numbers with equivalent electrical and mechanical specifications.
