306-020-521-112

Edgeboard Connectors Overview

The EDAC Inc. 306-020-521-112 is a dual-edge female card edge connector featuring 40 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes a single centerline row design and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector employs copper alloy contacts with gold plating for reliable signal transmission. Designed for panel mount installation via through-hole termination, the unit features a low-profile insulator body constructed from thermoplastic material. This configuration supports vertical mounting orientations and provides secure interconnection for standard edgeboard applications.

Edgeboard Connectors Feature Summary

• Single centerline row architecture providing efficient board space utilization
• Low-profile insulator body designed to minimize overall assembly height
• Gold-plated copper alloy contacts ensuring durable electrical performance
• Panel mount capability with through-hole solder termination

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• General-purpose electronic board-to-board connections

Edgeboard Connectors Procurement Notes

Verify that the target application requires a single centerline row configuration rather than a double centerline variant within the same series. Confirm the printed circuit board thickness aligns with the specified 0.062-inch nominal requirement to ensure proper mechanical retention. Ensure the panel mounting holes match the physical dimensions of the connector flanges. Check for RoHS compliance requirements if the end product mandates specific environmental standards. Validate that the gold contact plating meets the necessary corrosion resistance criteria for the operating environment.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface is sufficient for the signal count, as it offers a more compact footprint compared to dual-centerline alternatives. The 0.156-inch pitch is suitable for lower-density applications where high pin counts are not critical. Consider the low-profile design if vertical clearance within the enclosure is restricted. The green color coding may assist in visual identification during assembly processes. Evaluate the thermal stability of the thermoplastic insulator against the maximum operating temperature of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which specializes in standard card edge connectors. The series provides various options for contact spacing, row configurations, and mounting styles. The 306-020-521-112 specifically addresses needs for moderate density connections with robust panel mounting capabilities. It complements other parts in the lineup by offering a specialized single-row solution distinct from the higher-density multi-row variants available in the broader catalog.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 40-position count, 0.156-inch pitch, and single centerline row geometry. Verify that any alternative part supports the same 0.062-inch board thickness and panel mount installation method. Ensure the replacement uses compatible gold-plated copper alloy contacts and similar thermoplastic insulation materials. Cross-reference the mechanical drawing dimensions to guarantee fit within existing panel cutouts and mounting hardware.
