305-046-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-508 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features 46 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Rated for 5 A continuous current and 1800 VACrms insulation, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, ensuring reliable electrical performance in industrial environments.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design compatible with non-specified card types
• Vertical panel mount style with solder pin termination
• Gold-plated copper alloy contacts for enhanced conductivity
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Communication equipment utilizing modular board connections
• Medical devices needing reliable high-current interconnects
• Energy sector hardware with strict environmental operating ranges

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with existing polarizing key requirements before procurement. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement and electrical continuity during assembly.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 46-position interface is required with a 3.96 mm pitch. It is suitable for designs demanding vertical panel mounting and solder pin termination. Consider the 5 A current rating and wide temperature tolerance for harsh environments. Verify that the application does not require surface mount technology, as this component is strictly through-hole panel mount.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which specializes in standard card edge connectors with 3.96 mm spacing. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 305-046-521-508 specifically addresses the need for a 46-position dual-row connector with gold contacts and thermoplastic insulation.

Edgeboard Connectors Replacement Considerations
