306-026-420-112

Overview

The EDAC Inc. 306-026-420-112 is a standard card edge connector from the 306 series, designed for panel mount applications. It features 52 positions arranged in a single row with a 3.96 mm (0.156 inch) contact spacing. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Feature Summary

• Accepts PCBs with a nominal thickness of 1.57 mm
• Gold-plated copper alloy contacts ensure reliable conductivity
• Low profile insulator body design for space-constrained panels

Applications

• Panel-mounted electronic interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces

Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating and board thickness compatibility. Ensure the target application requires a single-row configuration with 3.96 mm pitch. Confirm that the panel mounting style aligns with the mechanical constraints of the enclosure design before finalizing procurement.

Selection Notes

Select this component when a vertical, panel-mount solution is required for single-sided or double-sided cards up to 1.57 mm thick. The 52-position count suits moderate-density signal routing. Verify that the operating environment stays within the -40°C to +105°C thermal limits and that the 5 A current rating meets the electrical load requirements of the connected circuitry.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its robust thermoplastic construction and standardized 3.96 mm spacing. The 306 series provides a versatile interface for connecting edgeboards to host systems, offering various position counts and mounting styles to accommodate diverse industrial and commercial hardware designs.

Replacement Considerations

Direct substitutes must match the 52-position count, single-row layout, 3.96 mm pitch, and panel mount orientation. Verify that any alternative component supports the same 1.57 mm board thickness and maintains equivalent electrical ratings for current and temperature operation.
