305-042-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-504 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch and a 3.56 mm row spacing. The connector utilizes female half-beam contacts made of copper alloy with gold plating, rated for 5 A current. It supports PCB thicknesses between 1.37 mm and 1.78 mm and employs solder lug termination for panel mounting.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure dual-edge card insertion
• Gold-plated copper alloy half-beam contacts ensure reliable electrical performance
• Thermoplastic polyester insulation provides structural stability and environmental resistance

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes to confirm exact physical dimensions and termination styles, as variations exist within the 305 series. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before integration. Confirm that the panel mounting style aligns with the mechanical design requirements of the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 42-position interface with a 3.96 mm pitch is required for dual-edge boards. The vertical panel mount orientation and solder lug termination are suitable for chassis-based installations. Consider the 5 A current rating and operating temperature range of -40°C to +105°C for environmental suitability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and configurations for card edge applications.
