IP68 Waterproof SP Series 4Pin Connector for Smart Toilet Control Modules

SD20/SP20 Square Flange Connector Design and Installation Guide

Choosing a Waterproof and Corrosion-Resistant Connector for Smart Toilet Control Modules

For the control module of a smart toilet, the primary decision factors are protection against moisture and cleaning chemicals, electrical safety, and ease of maintenance. The SP series waterproof connector (4Pin) with an IP68 rating is designed to meet these requirements.

Key Selection Criteria for Smart Toilet Connectors

• Environmental Protection: An IP68 rating ensures the connector is fully sealed against dust and can withstand continuous submersion in water, protecting against splashes and leaks.
• Chemical Resistance: The connector housing is resistant to corrosion from common toilet cleaning agents, including acidic and alkaline cleaners, ensuring long-term reliability in a bathroom environment.
• Electrical Configuration: This 4-pin connector uses 2 pins for 220V AC power supply and 2 pins for control signal transmission (e.g., flushing and heating commands), separating power from low-voltage signals.
• Safety Features: An anti-electric shock design with built-in leakage protection helps prevent electric shock during user operation.
• Maintenance: A plugging force of less than 15N allows for quick and easy module replacement by maintenance staff without special tools.

Application Fit and Installation Notes

This connector is suitable for the internal wiring of smart toilet control modules where a reliable, sealed connection is required. The low plugging force is a deliberate design choice for serviceability, but it is important to ensure the connector is fully seated and locked to maintain its IP68 rating during operation.

For similar applications requiring different pin counts or mounting styles, review the full range of waterproof connectors to match your specific control module layout.

Verifying Connector Suitability

Before finalizing your selection, confirm the following parameters against your module's specifications:

• Rated current and voltage for the 220V AC power pins.
• Signal voltage and current for the control pins.
• Operating temperature range for the bathroom environment.
• Mating cycles required for the expected service life.

If your application requires a different pin configuration, consider the 12G 2-Pin Waterproof Aviation Connector IP67 for lower-power signal-only connections.
