SP28/SD28 Panel Mount Connector Technical Drawing and Key Specifications

This technical drawing provides the verified measurements, material composition, and electrical ratings for the SP28/SD28 panel mount connector series. It is intended for design engineers, maintenance teams, and procurement specialists who need to confirm flange dimensions, pin configuration, and environmental protection before integrating the connector into a control cabinet, machine interface, or power distribution panel.

What the Drawing Covers

The drawing documents the physical envelope and mounting interface of the SP28/SD28 series. Use it to check panel cutout requirements, mating depth, and the mechanical clearance needed around the connector body. The material composition is listed for the housing, contacts, and sealing components so you can verify compatibility with your operating environment.

Electrical and Environmental Ratings

Before specifying this connector, confirm that the rated current, voltage, and insulation resistance meet your circuit requirements. The IP rating indicates the level of protection against dust and water ingress when the connector is properly mated and mounted. Note that environmental performance can be affected by cable selection, termination quality, and the condition of the panel seal.

Selection Checklist for Your Application

• Confirm the pin count and contact layout match your wiring scheme.
• Verify the panel cutout diameter and mounting hole pattern against your enclosure.
• Check the cable entry size and termination method (solder, crimp, or screw).
• Compare the rated current and voltage with your load profile, including inrush conditions.
• Confirm the operating temperature range and IP rating suit the installation environment.

Installation and Maintenance Notes

Proper panel preparation is essential for achieving the stated protection rating. Ensure the mounting surface is flat, clean, and free of burrs. Torque the mounting nut to the recommended value to avoid distorting the seal. During maintenance, inspect the O-ring or gasket for damage and replace it if there are signs of compression set or cracking.

For related panel mount options with different pin counts and current ratings, review the aviation plug connector series or the LD28/SP28 panel mount connector catalog.
