306-026-400-158

Overview

The EDAC Inc. 306-026-400-158 is a standard card edge connector featuring 52 positions with dual female contacts. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for non-specified board thicknesses, typically accommodating standard PCB dimensions. The connector employs tin plating on the contacts to ensure reliable signal transmission. Constructed with a green thermoplastic insulator body, this component belongs to the 306 series of headers. It is engineered for vertical panel mounting applications, providing a secure interface for edge-board connections in electronic assemblies requiring robust mechanical stability.

Feature Summary

• Dual edge female contact configuration for secure board insertion
• Vertical panel mount style for stable structural integration
• Green thermoplastic insulator body for electrical isolation
• Tin-plated contacts for corrosion resistance

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronics module interfaces

Procurement Notes

Verify the specific datasheet version for the 306-026-400-158 to confirm current RoHS compliance status and detailed dimensional tolerances. Ensure that the target printed circuit board thickness aligns with the connector's acceptance specifications prior to procurement. Cross-reference the manufacturer's official documentation for any updates regarding material composition or environmental operating limits to guarantee compatibility with the intended application environment.

Selection Notes

Select this connector when a dual-edge female interface with 52 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications needing wider spacing compared to high-density alternatives. Verify that the tin-plated contact finish meets the environmental requirements of the assembly. Confirm that the green insulator color coding aligns with internal manufacturing standards for visual identification during production processes.

Part Context

This component is part of the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic design needs. As a header type, it provides a fixed receptacle for mating with edge-board plugs. The 306 series is widely utilized in industries requiring reliable, standardized interconnection solutions for modular electronic systems.

Replacement Considerations

Direct substitutes within the same series include variations such as 306-026-400-178, which shares similar physical characteristics but may differ in contact plating or specific board thickness tolerances. Always verify pin count, pitch, and mounting orientation before substituting components to maintain mechanical and electrical integrity.
