305-026-500-507

Edgeboard Connectors Overview

The EDAC Inc. 305-026-500-507 is a standard card edge connector designed for panel mounting applications. It features a dual female configuration with 26 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Constructed with copper alloy contacts, it offers a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. The housing is made of green thermoplastic polyester, providing an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides high dielectric strength with 1800 VACrms rating
• Features gold-plated copper alloy contacts for reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control modules requiring polarized keying
• High-voltage circuit board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure correct contact type and flange characteristics. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 specifications if required by project standards.

Edgeboard Connectors Selection Notes

Select this component when panel mounting is required rather than PCB surface mount. The dual-row design supports higher density connections compared to single-row alternatives. Verify compatibility with polarizing keys if mechanical alignment is critical. Consider the 5 A current rating for power distribution needs within the system architecture.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust construction suitable for demanding environments. Components in this family typically feature thermoplastic polyester housings and gold-plated contacts. The 305 series provides versatile options for various position counts and mounting styles.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 26-position dual-row configurations. Ensure replacement parts maintain the 3.96 mm pitch and compatible board thickness range. Verify that alternative models support the same polarizing key requirements and electrical ratings.
