Level Switch – RF-OH21 Plastic Horizontally Mounted
This plastic level switch is horizontally mounted to give either a high level or low level signal and is reversible meaning that it can be either normally open or normally closed. The RF-OH21 is available with either internal or external mounting options and comes with an EPDM compression seal.
The switch comes with 300mm leads but can be made with various lead or cable lengths (please get in touch with your requirements, minimum order quantities may apply).
When the magnetic field of permanent magnet inside the float is moved into to the proximity of the reed switch inside the stationary stem, the reed switch contacts “snap” together and closes the electrical circuit. When the magnetic field is moved away from the reed switch, the reed switch contacts move apart and the circuit is opened.
