305-052-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-201 is a dual-edge female card edge connector designed for board-to-board or backplane applications. It features 52 positions arranged in two rows with a 0.156-inch (3.96mm) spacing. The contacts are made of copper alloy with a 10.0µin (0.25µm) gold plating thickness, utilizing a semi-bellows contact type for reliable engagement. The housing is constructed from green thermoplastic polyester, supporting PCB thicknesses between 0.054 and 0.070 inches. Rated for operation from -40°C to +105°C, this component ensures stable electrical performance in demanding environments.

Edgeboard Connectors Feature Summary

• Semi-bellows contact design provides secure mating force and low contact resistance
• Gold-plated copper alloy terminals ensure corrosion resistance and signal integrity
• Thermoplastic polyester insulation offers thermal stability and mechanical durability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's current ordering guide to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status aligns with project regulatory requirements. Cross-reference datasheet dimensions for mounting clearance validation.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with 0.156-inch spacing is required. Verify that the target PCB thickness falls within the 0.054 to 0.070-inch range. Consider the semi-bellows contact type for applications requiring robust mechanical retention. Ensure the operating temperature range meets environmental constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for general-purpose electronic interconnections. The 305-052 variant specifically addresses higher-density connection needs within the dual-row configuration family.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series parts with matching 52-position dual-edge specifications. Verify identical spacing, contact type, and PCB thickness compatibility when considering alternative part numbers.
