306-034-420-104

Overview

The EDAC Inc. 306-034-420-104 is a standard card edge connector receptacle featuring 68 positions arranged in a dual-edge configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a thickness range of 0.054 to 0.070 inches (1.37 mm to 1.78 mm). The component employs tin-plated copper alloy contacts with a solder pin termination type for secure board attachment. Designed for panel mount installation, it operates within a temperature range of -40°C to 105°C and is constructed from green thermoplastic polyester insulation.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required plating and termination specifications. Confirm that the selected variant matches the intended board thickness and mounting requirements. Cross-reference the part number with official EDAC documentation to validate availability status and compliance with relevant regulatory standards such as RoHS before finalizing procurement orders.

Selection Notes

Select this component when a high-density dual-edge connection is required for panel-mounted applications. Ensure the design accommodates the specified 0.156-inch pitch and supports the target PCB thickness range. Consider the tin plating option if cost-effectiveness is prioritized over the extended corrosion resistance offered by gold finishes. Verify that the thermal operating range aligns with the environmental conditions of the intended deployment scenario.
