306-027-520-112

Overview

The EDAC Inc. 306-027-520-112 is a standard card edge connector featuring 54 positions arranged in a dual-edge configuration with a single centerline row. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with a gold finish, providing a current rating of 5 A. Designed for panel mounting in a vertical orientation, the unit employs a thermoplastic insulator body and offers an insulation resistance of 5 GOhms, operating within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female connector design accommodating 54 positions
• Gold-plated cantilever contacts on copper alloy substrate
• Low-profile thermoplastic insulator body construction

Applications

• Panel-mounted electronic interconnections
• Industrial control system hardware integration
• Communication equipment board connections

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with your application requirements. Ensure that the dual-edge configuration and 3.96 mm pitch align with your PCB design specifications. Cross-reference the thermal and electrical ratings with your operational environment constraints before finalizing procurement decisions.

Selection Notes

Select this component when a high-density connection is required for thick PCBs up to 1.57 mm. The dual-edge layout maximizes pin count within a compact footprint compared to single-edge alternatives. Verify that the vertical panel mount style fits your enclosure design and that the gold contact finish meets your corrosion resistance needs.

Part Context

This connector belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series is characterized by robust mechanical designs suitable for demanding environments. The 306 series typically features thermoplastic housings and precise contact spacing options to support various industrial and commercial applications requiring reliable signal transmission.

Replacement Considerations

Consult official EDAC substitution guides for verified alternative part numbers. Ensure any replacement maintains the same 54-position count, 3.96 mm pitch, and dual-edge configuration. Verify that mechanical dimensions and mounting styles remain compatible with existing panel cutouts and PCB layouts.
