305-074-520-201

Edgeboard Connectors Overview

The EDAC Inc. 305-074-520-201 is a dual-edge female card edge connector featuring 74 positions arranged in two rows of 37 contacts each. It utilizes a 0.156-inch (3.96mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The component employs gold-plated semi-hemibulge contacts for reliable signal transmission and is housed in green thermoplastic polyester insulation. Designed for panel mount through-hole soldering, it operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct plating thickness and flange dimensions. Confirm that the required board thickness falls within the specified 0.054 to 0.070 inch range before procurement. Cross-reference the manufacturing date code to ensure compliance with current environmental regulations such as RoHS3. Validate that the supplier provides original manufacturer packaging to prevent counterfeit components.

Edgeboard Connectors Selection Notes

Select this connector when a high-density 74-position interface is required for dual-edge PCB applications. Ensure the mating board thickness aligns with the specified tolerance range to guarantee proper contact engagement. Consider the operating temperature range of -40°C to +105°C for environmental suitability. Verify that the panel mount form factor fits the mechanical constraints of the enclosure design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options for diverse electronic interconnection needs. The 305-074 variant specifically addresses applications requiring robust dual-sided connectivity with standardized spacing.
