Product: Float Switch Water Level Controller Model: STUKK2 Key benefits Automates liquid level control to prevent overflow and dryrun of pumps. Simple, reliable switching with both NO (normally open) and NC (normally closed) contacts for flexible wiring and control logic. Compact, corrosionresistant plastic housing and 4 m (13.1 ft) cable for easy installation and positioning. What this product does Detects water level changes and operates connected pumps or alarms based on the float position. Recommended for use with DC 24V control circuits; also provides AC switching capability per the rated current/voltage specifications below. Designed for repeated operation with an electrical endurance rating of 50,000 cycles. Specifications (as provided) Product Name: Float Switch Water Level Controller Model: STUKK2 Rated Current/Voltage: AC 10(8A) 250V10(4A)380V Recommended Voltage: DC 24V Working Temperature: 0°C 60°C Control Range: 0.2 m Electrical Endurance: 50,000 times Contacts: NO + NC Shape: Round Body Size: 10 x 8 x 4.5 cm / 3.9' x 4.3.1' x 1.8' (L*W*T) Cable Length: 4 m / 13.1 ft Housing Material: Plastic Color: Blue, Yellow Performance and compatibility notes Use the NO or NC contact depending on whether you need the circuit to close when the float rises or falls. Works within the listed temperature range (0°C to 60°C). Avoid prolonged use outside this range. Follow the rated AC current/voltage values and the recommended DC 24V for safe, longterm operation. Typical applications Residential and commercial water tanks: maintain set water levels and prevent overflow. Sump and pump control: start/stop pumps automatically to avoid dryrun and reduce manual intervention. Agricultural or aquaculture systems: manage water circulation, fill cycles, or reservoir levels with reliable switching. Installation and handling tips Mount the float on the cable at the required control depth (control range 0.2 m) and secure the cable to prevent unwanted movement. Verify electrical connections for NO/NC per your control system requirements and ensure voltages/currents do not exceed the rated values. Inspect periodically for wear or damage to the plastic housing and cable; if integrity is compromised. This STUKK2 float switch offers a compact, easytoinstall solution for automatic water level control where reliable switching and simple integration are required.
