305-046-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-203 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features 46 positions with a pitch of 3.96 mm (0.156 inches) and supports dual-edge card insertion. The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and has a current rating of 5 A. It accommodates board thicknesses within the range of 1.37 mm to 1.78 mm and operates effectively in temperatures between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design for secure integration
• Gold-plated copper alloy contacts for durability
• Dual-edge connection capability
• Supports polarizing keys for alignment

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation boards
• Embedded computing modules

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required position count and pitch before ordering. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment stays within the specified temperature limits of -40°C to +105°C. Check local distributor availability as stock levels may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Consider the 5 A current rating for power distribution needs. Verify that the housing material and insulation resistance meet the system's electrical safety requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts up to 86 contacts. The series is known for accepting both between-contact and in-contact polarizing keys. Similar models include the 305-048-521-203 and 305-038-520-502, differing primarily in position count and specific contact configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-048-521-203 and 305-038-520-502. These alternatives share identical pitch, mounting style, and electrical ratings but differ in the number of positions. Ensure the replacement matches the exact mechanical footprint and pin configuration of the original design.
