Description

This industrial-grade float switch operates on a simple buoyancy principle, where the rising or falling liquid level tilts the square float, mechanically actuating an internal hermetically sealed switch. The double-chamber design and final remolding ensure a completely watertight seal (IP68), preventing fluid ingress and guaranteeing trouble-free operation in non-flammable liquids, including water, sewage, oils, and weak chemical solutions.

The switch is rated for direct control of AC loads, making it suitable for automatic on/off control of pumps, motors, and solenoid valves, or for triggering high/low-level alarms. Its robust construction supports a high mechanical lifetime, while the electrical contacts are rated for frequent switching cycles within the specified temperature and pressure (0.1 MPa) limits.

Key Features

  • IP68 waterproof protection for continuous submersion and harsh liquid environments.
  • High-current switching capability: 10A @ 250V AC or 4A @ 380V AC.
  • Extended 3-meter PVC cable for flexible installation in deep tanks or remote sumps.
  • Durable plastic float housing (78x103.5mm) with high buoyancy for reliable level detection.
  • Hermetically sealed switch chamber prevents corrosion and ensures long-term reliability.
  • Wide operating temperature range from 0°C to 75°C.
  • Compatible with a range of non-flammable liquids including water, oil, and weak acids/bases.
  • High mechanical life rating of 500,000 actuation cycles.

Applications

  • Automatic pump control in water tanks, wells, and sump pits.
  • High/low-level alarm triggering in industrial storage tanks for oils or chemicals.
  • Liquid level management in HVAC condensation trays and drainage systems.
  • Level sensing in agricultural irrigation tanks and reservoirs.
  • Control device for magnetic valves in industrial fluid handling systems.

Frequently Asked Questions

What is the maximum electrical load this float switch can control?

This float switch is rated for two common AC industrial voltages. It can switch up to 10 Amps at 250 Volts AC, or up to 4 Amps at 380 Volts AC. Always ensure your connected pump, motor, or valve coil current does not exceed these ratings for safe and reliable operation.

Can this switch be used in corrosive liquids like acids?

The plastic float housing and hermetically sealed IP68 switch chamber provide resistance to weak acids, alkalis, oils, and sewage water. However, it is not designed for use with strong, concentrated, or highly corrosive chemicals. Always verify chemical compatibility for your specific application.

How do I wire and install this float switch for pump control?

Installation involves mounting the float at the desired trigger level in your tank, ensuring free vertical movement. The two wires from the 3-meter cable are connected in series with the power line to your pump motor or control relay. The switch acts as a normally-open (NO) or normally-closed (NC) contact, closing or opening the circuit when the liquid level raises or lowers the float.

What is the difference between mechanical life and electrical life?

Mechanical life (500,000 cycles) refers to the number of times the float can physically actuate the internal switch mechanism without failure. Electrical life (100,000 cycles) is the number of reliable on/off switching cycles under the rated electrical load. The switch may mechanically outlast its electrical contacts when switching high currents.
