305-018-556-507

Edgeboard Connectors Overview

The EDAC Inc. model 305-018-556-507 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features an 18-position dual-edge female configuration with a 3.96 mm (0.156 inch) pitch. The connector supports a PCB thickness range of 1.37 mm to 1.78 mm and utilizes gold-plated copper alloy contacts rated for 5 A current. The housing is green thermoplastic, providing insulation resistance of 5 GOhms and operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic housing provides structural integrity and insulation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Computing hardware module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness limits of 1.37 mm to 1.78 mm before integration. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 18-position count with the circuit design to prevent mismatched pinouts.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface is required for high-reliability applications. The 3.96 mm pitch accommodates standard board layouts while maintaining robust electrical performance. Consider the 5 A current rating for power distribution needs. The vertical orientation simplifies assembly in constrained panel spaces compared to right-angle alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-018-556-507 specifically addresses the need for 18-position dual-edge connectivity. It shares common family traits such as the 3.96 mm pitch and thermoplastic construction found across the broader product line.

Edgeboard Connectors Replacement Considerations

The 355-018-556-507 is a confirmed substitute variant within the same series. It maintains identical electrical and mechanical specifications but differs in housing color, which is black instead of green. Verify that color coding does not impact system identification requirements.
