305-056-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-056-520-503 is a dual female card edge connector from the 305 series, designed for panel mount applications. It features 56 positions with a 0.156-inch (3.96 mm) contact spacing and a 0.140-inch (3.56 mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a thermoplastic insulator, it operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual female configuration with low profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Flush mount flange with floating bobbin design for secure panel installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-panel connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 56-position count and 0.156-inch pitch before procurement. Confirm that the target application supports the specified 0.062-inch PCB thickness to ensure proper mechanical engagement. Check for RoHS compliance requirements against project specifications. Ensure the mounting style aligns with the available panel cutout dimensions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female interface is required for vertical panel mounting. The 0.156-inch pitch accommodates standard high-density interconnect needs. Consider the operating temperature range of -40°C to 105°C for environmental suitability. The gold plating provides corrosion resistance suitable for long-term industrial use.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing consistent electrical characteristics and material properties. The 305-056 variant specifically addresses applications needing 56 connection points in a dual-row format.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for alternative position counts if pinout compatibility allows. Verify mechanical fitment with existing panel designs before substituting with similar models from different manufacturers.
