305-070-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-070-500-508 is a standard card edge connector from the 305 series, designed for dual-edge card applications. It features 70 positions with a 3.96 mm (0.156 inch) pitch and a 2-row configuration. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. Designed for panel mounting, it accommodates board thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure dual-edge card insertion
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic insulator provides stability across wide temperature ranges
• Panel mount design with vertical orientation for structural integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board connections
• Energy management system modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 70-position count and 3.96 mm pitch before procurement. Confirm that the panel mounting style and vertical orientation align with the mechanical design constraints. Ensure the operating temperature range meets the environmental requirements of the target application. Check RoHS compliance status if restricted substances are a concern for the project specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch offers robust spacing compared to finer pitches, aiding in manufacturing tolerance. The gold plating is suitable for environments requiring corrosion resistance. Consider the panel mount requirement as this model does not support surface mount or through-hole board attachment directly.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge solutions. The series provides various position counts and mounting options to support diverse industrial and commercial applications. The 305 series is characterized by its durable thermoplastic housing and consistent electrical performance across different row configurations.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-070-500-568 and 305-070-520-508. Verify that any alternative maintains the identical 70-position count, 3.96 mm pitch, and dual-row female interface to ensure mechanical and electrical compatibility.
