305-022-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-022-521-558 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 48 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and a solder pin termination type. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches) and supports a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a low profile insulator body constructed from thermoplastic polyester
• Provides high dielectric strength with a 1800 VACrms voltage rating

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical interconnection
• Systems utilizing polarized card edge modules for alignment
• Industrial control units needing robust 5A current carrying capacity

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange and termination characteristics. Confirm compliance with RoHS3 and REACH regulations as specified in the manufacturer documentation. Ensure the selected variant aligns with the intended panel mounting style and vertical orientation requirements for the target application.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 48-position interface is required for thick PCBs. The 3.96 mm pitch suits applications where higher density is not critical but mechanical stability via polarizing keys is essential. Consider the 105°C maximum operating temperature and green color coding for system integration planning.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its ability to accept polarizing keys and its suitability for panel mount installations. The 305 series offers various position counts while maintaining consistent electrical ratings and mechanical interfaces across the family.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 48-position count, 3.96 mm pitch, and panel mount vertical configuration precisely.
