315-018-520-202

Edgeboard Connectors Overview

The EDAC Inc. 315-018-520-202 is a dual-edge female card edge connector designed for through-hole mounting. It features 18 positions with a 0.156-inch (3.96 mm) pitch and a 0.200-inch (5.08 mm) row spacing. The contacts are made of copper alloy with a gold plating thickness of 10.0 µin (0.25 µm). The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C. It accommodates board thicknesses from 0.054 to 0.070 inches (1.37–1.78 mm) and includes flanges with a 0.128-inch diameter.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration ensures reliable signal transmission across both sides of the circuit board.
• Gold-plated half-wave spring contacts provide durable connection performance and corrosion resistance.
• Thermoplastic polyester insulation offers stability within a wide operating temperature range.
• Flanged design facilitates secure panel or chassis mounting with top-opening access.

Edgeboard Connectors Applications

• Medical instrumentation and imaging systems
• Digital signal processing equipment
• Scientific instruments and rotary encoders

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required pin count and pitch specifications. Confirm RoHS compliance status if environmental regulations apply to the assembly. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical fit and electrical contact.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with a 3.96 mm pitch is required for vertical mounting. The 18-position count suits moderate-density applications. Verify that the through-hole termination method aligns with the manufacturing process. Consider the green housing color for visual identification during assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 315 series, which specializes in standard card edge connectors. The series provides various position counts and mounting options for industrial and commercial interconnect needs. The 315 series is characterized by its robust construction and compatibility with standard PCB fabrication techniques.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 315 series models with identical 18-position dual-edge configurations. Cross-reference dimensions such as the 0.156-inch pitch and overall height to ensure mechanical interchangeability without redesigning the host enclosure.
