LD20/SP20 Waterproof Docking Connector Dimensions, Specifications, and Materials

This page provides the verified dimensional, electrical, and material data for the LD20/SP20 waterproof docking connector series. Use this information to check panel cutouts, confirm pin counts, and verify environmental ratings before you integrate the connector into your equipment design.

Connector Series and Interface Overview

The LD20/SP20 series is a heavy-duty square docking connector platform. It is available in both plug and socket configurations for cable-to-panel or panel-to-panel docking applications. The series is designed for environments where a secure, waterproof connection is required during mating.

Key Selection Criteria

• Pin Count and Contact Layout: Confirm the exact number of contacts and the pin arrangement for your application. The LD20 and SP20 variants may differ in contact configuration.
• Mounting Style: Choose between cable-mount plugs and panel-mount receptacles. Verify the panel cutout dimensions against your enclosure before ordering.
• Environmental Protection: The connector is designed for waterproof applications. Verify the IP rating and the conditions under which it is maintained (mated vs. unmated).
• Electrical Ratings: Check the rated current and voltage for the specific contact size you plan to use. Derating may apply at elevated temperatures.
• Material Compatibility: Confirm the housing and contact materials are suitable for your operating environment, including temperature range and chemical exposure.

Dimensional and Specification Data

The figure below presents the dimensions, specifications, and materials for the LD20/SP20 waterproof docking connector. Refer to the drawing for exact measurements, tolerances, and material callouts.

Note: The dimensional drawing is the authoritative source for installation data. Always verify the drawing against your physical sample or the latest revision before creating production tooling.

Application Fit and Boundaries

This docking connector is suitable for applications requiring a robust, waterproof interface in industrial equipment, automation, and outdoor installations. It is not intended for high-vibration environments without additional strain relief or for continuous flexing applications. For those requirements, consider a different connector series.
