Standex Detect - Reed Liquid Level Sensors
Reed liquid level sensors use magnetic floats and reed switch technology to detect fluid levels. As the float moves with the liquid, it activates reed switches housed within a stem, providing a reliable on/off signal or triggering multiple level points. These sensors are highly energy-efficient, drawing no power until activated, making them ideal for battery-powered or low-energy applications.
They are available in vertical or horizontal mount configurations and can be customized for various fluid types, temperatures, and pressures. With options for stainless steel or plastic housings, reed sensors offer a simple, cost-effective solution for fluid level monitoring in automotive, industrial, HVAC, and appliance systems.

Cylindrical proximity sensors are housed in round enclosures for easy mounting in tight or standardized spaces. Available with Reed or Hall effect technology, they provide reliable detection of magnetic or metallic targets.
Magnetic Float NBR or Nitrile Butadiene Rubber floats have excellent resistance to petroleum-derived liquids such as oil and gasoline and can be used in high temperature applications as well. Magnetic Float PA or Polyamide floats are made of nylon, have a very high strength-to-weight ratio making them shock and abrasion resistant, enduring a pressure of 5 bar (73 PSI or 0.5 MPa). Magnetic Float PP (polypropylene) are rugged, highly resistant to many chemical solvents, bases and acids and have a water absorption of only 0.1%. V2A Floats are made of rust-proof stainless steel and are resistant to high temperatures making them ideal for the Food & Beverage industry among others.
