5pcs/lot P45 Plastic Ball Float Switch Low Voltage Water Level Liquid Sensor Controller for Fish Tank |

5pcs/lot P45 Plastic Ball Float Switch Low Voltage Water Level Liquid Sensor Controller for Fish Tank   Description Float level switch is a simple structure, easy to use level control devices, it does not provide power, no complicated circuit, it has a smaller volume than the general mechanical switch, long working life and other advantages. As long as the material selection is correct in shape, and of any nature or liquid pressure, temperature can be used, which in the shipbuilding industry, generating equipment, petrochemical, food industry, water treatment equipment, dyeing and finishing industry, hydraulic machinery, etc. have been widely applications.   How it works: liquid level sensor mainly by a magnetic reed switch and float composed of magnetic material inside the float, set up one or more magnetic reed switch in a closed non-magnetic metal pipe or plastic pipe, and then passed through a catheter or more with a magnetic float, and double-loop control using a fixed float and reed switch in the relevant position, the float rises or falls with the liquid, inside the ball close to the beginning of the use of reed contacts, generating on and off the action, for level control or direction (when the float near the reed switch is turned on; switch off when you leave).   Specification: Max Contact Rating : 10W Max Switching Voltage: 100VDC Max Switching Current: 0.5A Max Breakdown Voltage: 220VDC Max Carry Current: 1.0A Max Contact Resistance: 100mohm Temperature Rating: -20 to 80 celsius  Insulation Resistance: >10Ω Contact Impedance: <100m Float Ball Material: P.P   Package Included: 5 X P45 Low Level Float Switch
