305-026-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-026-521-202 is a standard dual-edge card edge connector featuring 26 positions with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. Designed for .062 inch nominal thickness printed circuit boards, it utilizes gold-plated copper alloy semi-bellows contacts housed in a green thermoplastic polyester insulator. The component supports a 5 A current rating, operates between -40°C and +105°C, and offers 5 GOhms insulation resistance.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with semi-bellows contact design for secure board engagement
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Green thermoplastic polyester insulator body provides structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Computer peripheral module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact finish thickness and housing color variations within the 305 series. Confirm that the selected variant matches the required PCB thickness tolerance of .062 inches. Ensure compliance with RoHS directives if applicable to your manufacturing region. Cross-reference the manufacturer datasheet for precise dimensional drawings before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with 3.96 mm pitch is required for robust signal transmission. The semi-bellows contact type offers superior retention force compared to standard finger contacts. Consider the green housing material for visual identification in multi-color assembly environments. Verify that the 5 A current rating meets the electrical load requirements of the target application circuitry.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard density card edge connectors. The series offers various position counts and mounting styles while maintaining consistent 3.96 mm spacing. It serves as a reliable interface solution for edgeboard applications requiring durable mechanical connection and stable electrical performance across industrial temperature ranges.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC part numbers sharing the 305 series prefix and identical 26-position count. Verify matching 3.96 mm pitch and dual-edge compatibility before substitution. Alternative manufacturers may offer equivalent specifications but require rigorous dimensional verification against the original datasheet.
