305-072-520-503

Edgeboard Connectors Overview

The EDAC 305-072-520-503 is a standard card edge connector receptacle featuring 72 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for PCBs with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts with a semi-spring termination type, secured via solder end connections. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body with flush mount flange characteristics
• Utilizes semi-spring contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing dual-edge card interfaces
• Automotive electronics modules needing robust thermal stability

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct flange features and termination style. Confirm that the required polarizing key compatibility matches the system design. Cross-reference the RoHS status and material specifications with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a 72-position dual-row interface is required for 0.062-inch thick boards. Ensure the application environment stays within the specified -40°C to +105°C operating range. Verify that the 5 A current rating and 1800 VACrms insulation voltage meet the circuit safety standards. Confirm panel mounting constraints align with the flush mount flange dimensions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and row configurations for diverse electronic assembly needs. The 305-072 variant specifically addresses high-pin-count applications requiring stable electrical connections in compact form factors.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 72-position layouts, such as 305-072-520-204 or 305-072-520-504, provided mechanical and electrical parameters are identical.
