305-046-520-502

Edgeboard Connectors Overview

The EDAC Inc. 305-046-520-502 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 46 positions arranged in a dual row with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic housing. It supports board thicknesses between 1.37 mm and 1.78 mm, offering a continuous current rating of 5 A and an insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Features half-beam contact type for reliable signal transmission
• Includes flange characteristics with top opening for flush mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge connections
• Telecommunications equipment utilizing dual-edge female connectors
• Test and measurement devices needing high insulation resistance

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure correct contact plating thickness and housing color match project requirements. Confirm that the target PCB board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Check RoHS compliance status if environmental regulations apply to your assembly process. Ensure compatibility with existing polarizing key accessories if used in your design.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with a 3.96 mm pitch is required for panel-mounted applications. Consider the 5 A current rating and 1800 VACrms dielectric strength for power or signal integrity needs. Choose this model over single-row variants if higher density is necessary within the same footprint constraints. Verify that the vertical orientation aligns with the system's mechanical layout and cable routing requirements.

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 configurations to accommodate different circuit board sizes. The 305 series is known for its durability and consistent performance in demanding environments, making it a common choice for industrial and commercial interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes for variations in plating or housing material. Cross-series replacements require matching the 3.96 mm pitch and dual-row configuration while verifying mechanical fit and electrical ratings.
