305-032-521-278

Edgeboard Connectors Overview

The EDAC Inc. 305-032-521-278 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual-row configuration providing 32 positions with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a solder lug termination type. It is rated for 5 A continuous current and supports printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The insulator body is constructed from thermoplastic material, offering a low-profile design suitable for dense mounting environments.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact panel integration
• Provides robust electrical performance with a 5A continuous current rating

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical card edge interfaces
• Industrial control systems utilizing standardized PCB modules
• Communication equipment housing modular circuit cards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct flange and termination specifications. Confirm that the required polarizing key compatibility matches the intended PCB design. Check current availability status as distribution may vary by region. Ensure the selected variant meets the necessary environmental certifications such as RoHS compliance for the target application market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 32-position interface with a 3.96 mm pitch is required for vertical panel mounting. Consider the 1.57 mm board thickness constraint during mechanical design. Evaluate the need for polarizing key support if precise card insertion is critical. Compare against the 315 series if threaded flange mounting is preferred over the standard flush installation provided by this model.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their 0.156-inch contact spacing and versatile mounting options. The series includes various position counts and termination styles to accommodate different PCB densities. The 305-032-521-278 specifically represents a mid-range position count within this family, balancing connectivity density with physical footprint constraints.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and pitch but different suffixes for varied flange or termination options. Cross-series replacements like the 315 series offer similar electrical characteristics but differ in mounting hardware, such as threaded versus flush flanges. Verify mechanical dimensions and insulation resistance before substituting.
