305-026-521-508

Edgeboard Connectors Overview

The EDAC 305-026-521-508 is a standard card edge connector header featuring 26 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm. The connector employs gold-plated copper alloy contacts with a half-bevel termination style for reliable signal transmission. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C and is constructed from thermoplastic polyester insulation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body designed for space-constrained panel mount applications
• Provides high dielectric strength with a 1800 VACrms rating

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Medical device internal circuitry
• Consumer electronics module integration

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct contact plating thickness and housing color specifications. Confirm that the target PCB design accommodates the required 1.57 mm thickness tolerance. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 and REACH regulations for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel mounting. Consider the 5 A current rating and 1800 VACrms insulation capability for robust electrical performance. Verify compatibility with polarizing key requirements if mechanical locking is necessary. Ensure the application environment falls within the specified -40°C to +105°C operating temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and termination styles to support diverse board-to-board and board-to-panel connections. The 305 series is characterized by its durable thermoplastic construction and reliable gold-plated contact systems.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for direct substitutes with different position counts or termination types. Cross-reference with other EDAC series such as 315 or 355 only if dimensional and electrical parameters match exactly.
