SD20/SP20 Docking Connector Dimensions and Specifications

SP20/SD20 Right-Angle Docking Connector Dimensions and Materials

SD20/SP20 Docking Connector Overview

This technical overview covers the SD20/SP20 docking connector series, presenting verified dimensions, electrical specifications, and material options. The content is intended for design engineers, procurement specialists, and maintenance teams who need to confirm interface compatibility, mounting style, and environmental ratings before specifying a connector for industrial equipment, charging systems, or data transfer applications.

Series Scope and Interface Configuration

The SD20/SP20 series comprises a docking connector pair designed for blind-mating applications where a plug and socket must align reliably in confined or automated environments. The series is available in multiple pin counts and configurations to suit different power and signal requirements. Confirm the gender, pin layout, and keying orientation of your mating half before ordering, as these factors determine mechanical fit and electrical continuity.

Available Configurations

• Straight and right-angle versions for cable or panel mounting flexibility
• Flange and square flange mounting options for secure panel installation
• Multiple pin counts to match power, signal, or mixed circuits

Electrical and Environmental Specifications

Rated values are provided for reference; actual performance depends on application conditions such as ambient temperature, cable gauge, and mating cycle frequency. Always derate current ratings when operating near the upper temperature limit or with reduced conductor cross-sections.

Key Electrical Parameters

• Rated current and voltage per contact configuration
• Contact resistance values for power and signal circuits
• Insulation resistance under specified test conditions

Environmental Protection

The SD20/SP20 series is designed for industrial environments where dust, moisture, and vibration are present. Verify the IP rating for your specific configuration and note that waterproof performance applies only when the connector is properly mated and, where applicable, locked. Unmated connectors do not retain their ingress protection rating.

Materials and Construction

Housing materials, contact plating, and sealing elements are selected for corrosion resistance and mechanical durability. Confirm the material options for your operating environment, particularly if the connector will be exposed to chemicals, salt spray, or extreme temperatures. Contact plating affects both electrical performance and mating cycle life.

Termination and Cable Range

Termination methods include solder, crimp, or screw types depending on the configuration. Verify the acceptable cable diameter range for your chosen housing and contact size to ensure a proper seal and strain relief. Incorrect cable selection can compromise both electrical performance and ingress protection.

Installation and Maintenance Considerations

Proper panel cutout dimensions, mounting torque, and mating alignment are critical for reliable long-term operation. Refer to the installation guide for your specific flange style. Periodic inspection of contacts, seals, and locking mechanisms is recommended in high-vibration or high-cycle applications.

Selection Checklist

• Confirm pin count and contact layout match your circuit requirements
• Verify gender and keying orientation of the mating connector
• Check rated current and voltage against your load profile
• Confirm IP rating and temperature range for your environment
• Select the correct mounting style (flange, square flange, cable) for your panel
• Verify cable diameter and termination method compatibility
