305-026-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-512 is a standard card edge connector from the 305 series, designed for dual female board-to-board connections. It features 26 positions with a 3.96 mm (0.156 inch) pitch and gold-plated copper alloy contacts. The component utilizes a solder pin termination method and is constructed with a thermoplastic polyester insulator body. Rated for 5 A current, it supports PCB thicknesses ranging from 1.37 mm to 1.78 mm. Operating within a temperature range of -40°C to +105°C, this vertical panel mount header ensures reliable signal transmission in industrial applications.

Edgeboard Connectors Feature Summary

• Dual row female configuration for secure double-sided card edge mating
• Gold-plated half-beam spring contact design for low insertion force and high cycle durability
• Thermoplastic polyester housing provides thermal stability and chemical resistance
• Vertical panel mount style with solder pin termination for robust mechanical fixation

Edgeboard Connectors Applications

• Industrial control system I/O modules
• Telecommunications backplane interconnects
• Automotive electronic control units
• Medical device instrumentation boards
• Test and measurement equipment interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 26-position dual row configuration and 3.96 mm pitch. Confirm the insulation material is thermoplastic polyester and the contact plating is gold. Ensure the operating temperature range meets the application's environmental requirements. Check for RoHS compliance documentation if restricted substances are prohibited. Validate that the panel mount style aligns with the chassis design specifications.

Edgeboard Connectors Selection Notes

Select this connector when a dual-sided card edge interface is required for higher density signal routing. The 3.96 mm pitch accommodates standard PCB trace widths while maintaining adequate spacing. The vertical orientation simplifies assembly into panel-mounted enclosures. Consider the 5 A current rating for power distribution needs alongside signal lines. The robust copper alloy construction ensures long-term reliability in vibration-prone environments.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial electronics. The series offers various position counts and mounting styles to suit different board densities. The 305-026 variant specifically addresses applications requiring moderate pin counts with dual-row connectivity. It complements other series like 315 and 355 by providing a cost-effective solution for standard PCB thicknesses.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 26-position dual row configurations and matching 3.96 mm pitch. Verify that alternative components maintain the same thermoplastic polyester insulation and gold contact plating. Cross-reference mechanical drawings to ensure panel cutout dimensions and mounting hole patterns are compatible. Ensure the replacement supports the same PCB thickness range of 1.37 mm to 1.78 mm.
