IP68 Waterproof SP28/SD28 Panel Mount Connector 2-26 Pin

IP68 Waterproof SP28 / SD28 Rear Nut Mount Connector – Heavy-Duty Field Wiring Solution

The SP28 / SD28 IP68 Waterproof Rear Nut Mount Connector is designed for industrial equipment that requires a robust, flexible, and fully sealed cable-to-cable connection. Built for harsh environments, this series ensures stable electrical performance while maintaining high-level protection against water, dust, and mechanical stress.

As a rear nut mount design, it is ideal for field wiring, equipment extension, and modular system connections where installation flexibility and reliability are equally important.

Designed for Real Installation Conditions

In practical industrial applications, connectors are often exposed to vibration, movement, and frequent maintenance. This series is engineered to solve these challenges by providing:

• Secure cable-to-cable connection in field environments
• Stable transmission for power and multi-signal lines
• Flexible installation without panel limitations
• Reliable sealing for outdoor and industrial use

The structure is optimized to ensure stable mating performance even under repeated connection cycles.

Selection and Installation Considerations

When selecting the SP28 / SD28 rear nut mount connector, consider the following decision points:

• Pin count and layout: Confirm the number of cores (2-26 pin) and the required pinout for your power or signal lines.
• Mating side: Verify whether the mating connector is a plug or socket, and whether it is a cable mount or panel mount version.
• Cable preparation: Ensure the cable outside diameter and conductor size are compatible with the connector's termination range.
• Environmental exposure: Confirm the IP68 rating is suitable for your submersion depth and duration requirements.
• Mechanical stress: Evaluate vibration levels and mating cycles to confirm the threaded locking system meets your application needs.

For detailed electrical ratings, contact dimensions, and material specifications, refer to the SP28/SD28 Panel Mount Connector Technical Specifications.

Suitable and Unsuitable Applications

Suitable for: Outdoor electrical enclosures, industrial automation panels, marine equipment, and modular systems requiring a sealed, rear nut mount connection.

Not suitable for: Applications requiring continuous submersion beyond the IP68 test conditions, or environments where the connector will be mated and unmated while under load without proper de-energizing.
