305-040-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-040-521-201 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a solder pin termination method. It is rated for 5 A continuous current and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic polyester, supporting PCB thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Accepts both between-contact and in-contact polarizing keys for secure positioning
• Features semi-bellows contact type for reliable signal transmission
• Constructed with thermoplastic polyester insulation for durability

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical interconnect
• Dual-edge card interface systems
• Industrial control modules operating in extreme temperatures

Edgeboard Connectors Procurement Notes

Verify the specific suffix against the manufacturer's official ordering guide to confirm exact termination style and packaging. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the required polarizing key type matches the available options for this series. Cross-reference the RoHS status if environmental compliance is mandatory for the end application.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge cards. The 40-position count and 3.96 mm pitch define the physical footprint. Consider the 5 A current rating for power distribution needs. The green thermoplastic body provides visual identification and thermal stability up to 105°C. Verify that the solder pin termination aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles. The 305-040-521-201 specifically addresses the need for high-reliability connections in panel environments. It shares design characteristics with other parts in the 305 family, such as compatible polarizing keys and similar material specifications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 40 positions and 3.96 mm pitch. Verify that alternative parts support the same vertical panel mount style and solder pin termination. Ensure the replacement maintains the 5 A current rating and compatible PCB thickness range.
