Model LS - Miniature Liquid Level Sensor
- Compact Size
- Low Cost
- Reliability / Long Life switch life
- Can be used in wide range of liquids
- Perfect solution for standard assembly parts
General Description
These miniature liquid level sensors are designed for reliable operation in small tanks and containers. Their rugged design and careful engineering makes them suitable for OEM and large colume applications.
Operational Decription
These level sensors contain hermetically sealed reed switches in the stem and a permanent magnet in the float. As the float rises or falls with the level of the liquid, the reed switch activates by the magnet in the float. The operation of the switch, normally open or normally close, is easily changed by removing a retainer and inverting the float.
Conformity
Hygienic standards of Food, additives, etc. by Japan Food Research Laboratories.
Some of sensors are conformed by RoHS directive. Six materials such as Lead, Mercury, Hexavalent Chromium, Polybrominated Biphenyls, Polybrominated Diphenyl Ethers, and Cadmium are not contained to these products.
