305-040-556-212

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-212 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual-row configuration with a pitch of 3.96 mm (0.156 inches). The connector accepts PCBs with a thickness of 1.57 mm and includes a card slot depth of 7.49 mm. Contacts are made of copper alloy with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided printed circuit boards for high-density interconnects.
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance over repeated mating cycles.
• Thermoplastic housing offers mechanical stability and electrical insulation suitable for industrial environments.
• Vertical panel mount style facilitates direct integration into chassis or enclosure panels.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standardized card edge interfaces
• Medical devices needing reliable high-voltage insulation properties
• Energy sector hardware demanding wide operational temperature ranges

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm pin count, termination type, and insulation color. Ensure compatibility with the target PCB thickness of 1.57 mm before ordering. Confirm that the dual-row configuration matches the system layout requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface is required for 40-position connections with a 3.96 mm pitch. The 5 A current rating and 1800 VACrms insulation voltage make it suitable for applications exceeding standard low-power limits. Consider the vertical panel mount style for fixed installations where space constraints favor a perpendicular connection profile relative to the mounting surface.
