305-052-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-052-520-503 is a standard card edge connector from the 305 series, designed for vertical panel mounting 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 accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating, it ensures reliable electrical performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for secure board insertion
• Vertical panel mount design for stable structural integration
• Gold-plated copper alloy contacts for corrosion resistance
• Compatible with 1.57 mm nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Medical equipment interface modules
• Agricultural technology hardware connections
• General-purpose electronic assembly headers

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness and material specifications. Confirm RoHS compliance status through the manufacturer's current datasheet or certification documents before procurement. Ensure that the selected variant matches the required panel mounting orientation and PCB thickness tolerance for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a high-density 52-position connection is required for double-sided card edge applications. The 3.96 mm pitch offers a balance between signal density and mechanical stability. Consider the vertical mounting style for space-constrained panel installations where board insertion occurs perpendicular to the connector body. Verify thermal requirements against the specified -40°C to +105°C operational 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 provides various position counts and mounting styles to accommodate different board designs. The 305 series is characterized by its durable thermoplastic insulator and reliable solder pin termination, ensuring long-term connectivity in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-052-520-201 or 305-052-520-504 if physical dimensions or specific plating requirements differ. Ensure that any substitute maintains the same 52-position count, 3.96 mm pitch, and dual-row female configuration to guarantee mechanical compatibility.
