305-042-520-212

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-212 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 42 positions and a pitch of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm) and employs a solder pin termination type. Constructed with a thermoplastic polyester insulator, it supports a PCB thickness range of 1.37 mm to 1.78 mm. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for reliable board-to-board or backplane connections
• Gold-plated copper alloy contacts ensure low contact resistance and corrosion resistance
• Thermoplastic polyester housing provides structural stability and high insulation resistance
• Vertical panel mount design with solder pin termination for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, flange dimensions, and material certifications. Ensure compatibility with the target PCB thickness specifications before procurement. Cross-reference the RoHS status and REACH compliance requirements with current regulatory standards applicable in your region. Confirm that the vertical mounting style aligns with the mechanical constraints of the enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and -40°C to +105°C operating temperature range for environmental suitability. Evaluate the need for gold plating on copper alloy contacts for long-term reliability in high-cycle applications. Compare against other series if different PCB thickness tolerances or termination types are necessary.
