305-052-520-507

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-507 is a standard card edge connector from the 305 series, designed for panel mount applications. It features a dual female configuration with 52 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm. Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, ensuring reliable signal transmission.

Edgeboard Connectors Feature Summary

• Dual-edge female design accommodates non-specified board types
• Gold-plated copper alloy contacts ensure corrosion resistance
• Panel mount installation with vertical orientation
• Thermoplastic insulator body provides structural stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes
• Test and measurement instrumentation interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, termination style, and flange characteristics. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS compliance status and lead time requirements directly with authorized distributors prior to procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-current 5 A connection is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch offers reduced density compared to standard 2.54 mm connectors, suitable for power or mixed-signal applications. Verify that the panel mounting holes align with the M3 threaded inserts specified in the mechanical drawings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series is characterized by its ability to handle thicker PCBs and higher current ratings compared to low-profile variants. The 305 series is widely used in industrial environments where vibration resistance and secure panel mounting are critical operational requirements.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same family include 305-050-520-507 (50 positions) and 305-054-520-507 (54 positions), provided the position count difference is acceptable. For different spacing, consider the 845 series for 2.54 mm pitch applications.
