SP28/SD28 Square Flange Connector: Dimensional, Material, and Specification Overview

This page provides the detailed dimensions, specifications, and materials for the SP28/SD28 Square Flange Connector. Use this information to verify mechanical fit, electrical ratings, and environmental suitability for your industrial wiring application before ordering.

Key Selection Criteria for the SP28/SD28 Connector

When evaluating this square flange connector for your equipment, focus on these core decision points:

• Mounting Interface: Confirm the square flange cutout dimensions and panel thickness requirements for a secure, sealed installation.
• Electrical Ratings: Verify the current and voltage ratings against your actual load requirements, considering any derating factors for continuous operation or elevated temperatures.
• Environmental Protection: Check the IP rating and operating temperature range to ensure the connector meets the demands of your specific environment, whether indoor, outdoor, or washdown.
• Termination Method: Determine if the connector supports solder, crimp, or screw termination to match your assembly process and maintenance needs.
• Material Compatibility: Review the housing, insert, and contact materials for corrosion resistance and suitability with your application's chemical or moisture exposure.

Understanding the Specifications

The performance of the SP28/SD28 connector is defined by its electrical limits, mechanical construction, and material properties. The following points clarify how to interpret the technical data:

• Rated vs. Derated Values: Rated values are tested under ideal conditions. For real-world applications, especially with multiple contacts carrying current simultaneously, apply appropriate derating to ensure reliable long-term performance.
• Mating Cycles: The specified number of mating cycles indicates the mechanical durability of the connector. This is a key factor for applications requiring frequent disconnection.
• Contact Resistance: Lower contact resistance reduces heat generation and power loss, which is critical for high-current applications.

Application Boundaries

This square flange connector is designed for specific use cases. It is suitable for equipment requiring a robust, panel-mounted connection point. However, it is not a universal solution. Verify that the connector's specifications align with your application's requirements for voltage, current, and environmental exposure. If your application demands a different pin count, mounting style, or higher ingress protection, consider reviewing other series in our Aviation Plug Connectors range.
