305-068-521-278

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-278 is a standard card edge connector from the 305 series, designed for panel mounting with vertical orientation. It features 68 positions in a dual configuration with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It is compatible with non-specified dual-edge cards having a thickness range of 0.054 to 0.070 inches (1.37 to 1.78 mm). The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm plating thickness and flange characteristics. Ensure compatibility with the target PCB thickness specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the part number with official EDAC documentation to avoid substitution errors during assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density 68-position connection is required for dual-edge circuit boards. The 3.96 mm pitch accommodates standard industrial board layouts. Verify that the application environment falls within the specified temperature range. Consider the panel mount style for fixed installations rather than cable-to-board connections.
