• Switching Current: Up to 1.5A
• Contact Rating: 10W to 50W (model-dependent)
• Operating Temperature: -10°C to +120°C
• Working Pressure: 1 MPa (maximum 5 MPa)
• Contact Type: Reed switch (N/O or N/C, reversible by float orientation)
• Protection Class: Typically IP40​

✅ Features

• Dual Float Design: Provides high and low-level detection within a single unit, enhancing control accuracy.
• Versatile Mounting: Suitable for vertical installation in tanks and reservoirs.
• High Sensitivity: Utilizes reed switch technology for precise liquid level detection.
• Corrosion Resistance: Constructed from 304 stainless steel, ensuring durability in various liquid environments.
• Wide Application: Ideal for controlling pumps, alarms, and indicators in water treatment, chemical processing, and other industries.​

⚠️ Installation Notes

• The float switch cannot directly control high-power devices like solenoid valves or large pumps. It is recommended to use a small relay (e.g., HH54P) or an AC contactor for such applications.
• The action range of the two floats is approximately 10mm. For applications requiring a larger control range, consider using multiple float switches or adjustable mounting positions.​
