305-020-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-020-521-507 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features a 3.96 mm (0.156 inch) pitch with 20 positions arranged in a double row configuration. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator. Rated for 5 A current at +105°C maximum operating temperature, it supports PCB mounting with solder termination.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge cards
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester insulation providing structural stability
• Panel-mount flange design with M3 threaded inserts

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 507 corresponds to the required flange and mounting style, as variations exist within the 305 series. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance and material specifications before finalizing orders.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch dual-edge connector is required for panel-mounted installations. The M3 threaded insert flange facilitates secure mechanical attachment. Consider the 5 A current rating and -40°C to +105°C operating temperature range against environmental conditions. Verify that the 20-position count aligns with the circuit board interface requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various pitch options and mounting styles for card edge applications. The 305 series is characterized by robust construction and standardized dimensions, allowing for interchangeability within compatible system designs while maintaining high reliability in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 20-position counts and 3.96 mm pitch, such as 305-020-521-202, provided the flange and mounting configurations match the application requirements.
