305-040-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-040-555-268 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual-row configuration with 40 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing is specified at 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with low profile insulator body
• Dual-row configuration accepting 0.062 inch nominal PCB thickness
• Gold-plated copper alloy contacts for corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel connections
• Communication equipment interface modules
• Medical device internal board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical variations such as flange type or screw thread specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm that the gold plating thickness meets the application's durability needs.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount solution is required for high-density interconnects. The 3.96 mm pitch allows for substantial trace routing on the card edge. Verify that the 5 A current rating aligns with the system's power distribution requirements. Consider the operating temperature range if the environment exceeds standard industrial limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles, including panel and board edge options. The 305 series is widely used in general-purpose electronic assemblies where reliable, solder-pin termination is preferred over surface mount technologies.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305, 315, and 355 Series Ordering Guide for direct substitutes. Alternative part numbers may vary by position count or flange characteristics while maintaining identical electrical parameters.
