306-020-500-168

Overview

The EDAC Inc. 306-020-500-168 is a dual-edge female card edge connector from the 306 series, designed for panel mounting. It features 40 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with gold plating and utilize a cantilever spring design. The housing is green thermoplastic polyester, accommodating board thicknesses between 0.054 and 0.070 inches. It operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for reliable signal transmission
• Panel mount installation with flush-mount flange featuring top openings
• Gold-plated copper alloy contacts ensure corrosion resistance and conductivity
• Thermoplastic polyester insulation provides stability across specified operating temperatures

Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Consumer electronics assemblies needing high-density connections
• Test and measurement instrumentation boards

Procurement Notes

Verify that the replacement part number matches the specific 306 series designation and contact count. Confirm compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Ensure the panel mounting style aligns with the mechanical enclosure design. Check for RoHS compliance requirements if applicable to the final assembly specifications.

Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. Consider the cantilever contact type for ease of insertion and removal during maintenance. Evaluate the panel mount requirement against available chassis space. Verify that the operating temperature range meets the environmental conditions of the intended application site.

Part Context

This connector belongs to the EDAC 306 series, which specializes in card edge connectors for various industrial and commercial applications. The series offers multiple position counts and mounting styles to support diverse electronic module designs.
