306-023-521-112

Overview

The EDAC Inc. 306-023-521-112 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 46 positions arranged in two rows with a 0.156 inch (3.96 mm) contact spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts and gold plating, it utilizes a thermoplastic insulator body. This component supports vertical panel mount installation and provides reliable electrical interconnection for single-sided or dual-sided edge cards.

Feature Summary

• Dual-edge configuration accommodating two rows of contacts for increased pin density
• Low-profile insulator body design optimized for space-constrained panel installations
• Gold-plated copper alloy contacts ensuring durable signal transmission
• Vertical mounting style compatible with standard panel cutouts

Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment utilizing dual-sided edge cards
• Test and measurement instrumentation with high-density I/O needs
• Automotive electronics modules demanding reliable thermal stability

Procurement Notes

Verify that the target application requires a dual-edge connector rather than a single-edge variant, as this part accommodates two rows of contacts. Confirm that the PCB thickness matches the specified 1.57 mm nominal requirement to ensure proper mechanical retention. Check regional availability constraints, as distribution channels may indicate limited stock or specific shipping restrictions for this manufacturer number. Ensure compatibility with existing panel mounting hardware before finalizing procurement orders.

Selection Notes

Select this model when a dual-row interface is necessary for the specific edge card design. The 3.96 mm pitch offers a balance between pin count and spacing reliability. Consider the thermoplastic housing material for general environmental resistance. Evaluate the vertical orientation against available panel space. Compare against single-edge alternatives if only one row of connections is functionally required to optimize cost and complexity.

Part Context

This component belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series is characterized by its versatility in handling various board thicknesses and its suitability for panel-mount applications. The 306 series typically employs thermoplastic materials for the insulator, providing a cost-effective solution for general-purpose electronic interconnections where high temperature ratings are not the primary constraint.

Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and spacing but different termination or mounting variations. Verify that any replacement maintains the dual-edge configuration and 1.57 mm board thickness acceptance. Cross-reference with EDAC's ordering guide to confirm equivalent electrical ratings and mechanical dimensions before swapping components.
