305-034-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-034-521-502 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features a dual-edge female configuration with 34 positions and a 3.96 mm (0.156 inch) pitch. The contacts are gold-plated copper alloy, rated for 5 A current, and terminate via solder lugs. The housing is green thermoplastic polyester, supporting board thicknesses of 1.37 mm to 1.78 mm, with an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Panel mount design with vertical installation angle
• Thermoplastic polyester insulation provides thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB edge card thickness range of 1.37 mm to 1.78 mm. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the RoHS status if environmental compliance is mandatory for the application.

Edgeboard Connectors Selection Notes

Select this component when a high-current 5 A rating and robust 3.96 mm pitch are required for vertical panel integration. The dual-edge female design suits applications needing stable connection for thick PCBs within the specified tolerance. Consider the green thermoplastic housing for general industrial environments where temperatures do not exceed 105°C. Evaluate alternative series like 345 if a smaller 2.54 mm pitch is needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their larger 3.96 mm pitch and high current capacity compared to finer-pitch alternatives. The series offers various position counts and termination styles, catering to heavy-duty industrial and telecommunications applications requiring durable panel-mounted interfaces.

Edgeboard Connectors Replacement Considerations

The 305-034-521-502 does not have a direct single-part substitute due to its specific combination of 34 positions, 3.96 mm pitch, and dual-edge female configuration. Similar EDAC parts in the 305 series may differ in position count or termination type. Verify mechanical fit and electrical ratings before considering any cross-referenced components.
