305-064-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-064-521-503 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 64 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a low-profile insulator body constructed from green thermoplastic material
• Provides reliable electrical connection through gold-plated semi-beryllium copper contacts

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement instrumentation needing high-density signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct pin count, plating specification, and flange characteristics. Confirm that the target PCB thickness aligns with the connector's acceptance range. Check regional availability as distribution status may vary by location. Ensure compliance with RoHS3 and REACH regulations required for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 64-position interface is required for vertical panel mounting. The 0.156-inch pitch suits applications needing moderate density without excessive height constraints. Consider the 5A current rating and 1800VACrms dielectric strength for power and signal integrity requirements. Evaluate the need for polarizing key compatibility if mechanical locking is necessary for the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination styles to accommodate different design architectures. The 305-064 variant specifically addresses high-pin-count applications requiring durable, gold-plated connections in industrial environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 64-position dual-row configurations, such as 305-064-520-503 or 305-064-521-512, provided the termination style and flange dimensions are identical. Cross-brand replacements require strict verification of pitch, board thickness tolerance, and mating force specifications.
