306-035-500-104

Overview

The EDAC Inc. 306-035-500-104 is a dual-row card edge connector designed for panel mounting applications. It features 70 positions with a 0.156-inch (3.96mm) contact spacing. The connector utilizes female, cantilever contacts with gold plating to ensure reliable signal transmission. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The insulator body is green thermoplastic polyester, and the unit operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female contact configuration provides robust connection stability for double-sided card edges.
• Gold-plated cantilever contacts offer low insertion force and high cycle durability.
• Panel mount design with flange features ensures secure mechanical installation.

Applications

• Industrial control systems requiring durable edge board connections
• Telecommunications equipment interface modules
• Test and measurement instrumentation backplanes

Procurement Notes

Verify that the target PCB thickness falls within the specified 0.054 to 0.070 inch range to ensure proper contact engagement. Confirm that the mating card edge geometry matches the dual-row specification. Check for RoHS compliance requirements if operating in regulated environments. Ensure panel cutout dimensions align with the connector's flange specifications for correct mounting.

Selection Notes

Select this model when a dual-row connection with 0.156-inch pitch is required for higher pin count applications. Consider the single central row alternative if space constraints prevent dual-row usage. Evaluate the thermal rating against system operating conditions. Compare mechanical retention needs against other series options like the 316 or 356 families.

Part Context

This component belongs to the EDAC 306 Series, which specializes in standard pitch card edge connectors. The series offers various position counts and termination styles. The 306-035 variant specifically addresses mid-range density requirements. It shares design characteristics with related models such as the 306-030 and 306-043, differing primarily in contact count and specific housing dimensions.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 70-position dual-row configurations. Verify compatibility with existing PCB layouts before swapping. Cross-reference with 316 or 356 series only if pitch and mechanical footprint differences are acceptable.
