The O series offers a wide array of electro-optic liquid level switches that are typically used in non-coating substances. These miniature optical point level detection switches are integrated with a phototransistor housed in a sensor tip capable of generating a digital output that indicates existing and absent liquids. Each individual with consists of a refractive index that is altered once it is submerged in water therefore specifying the level. Available in a broad range of wetted components and operating scope, these switches also come in optimized temperature functionality. They are specially engineered to adapt to specific requirements demanded by the user and can be quoted as well. The O series feature a solid-state technology and a number of voltage outputs.
