1 FINE AUTOMATION SIDE MOUNTING FLOAT SWITCH TEL: , FAX: , http: // PRINCIPLE Simple theory as liquid buoyancy is utilized for the main principle of this "LF" series. A change of liquid level correspondingly travels the float to extreme levels up and down. The reed switch is thus "NC" and "NO" exchanged as well as the permanent magnet on pivot will have mutual repellence to the other one inside the housing for like poles, which the micro switch is buttonpushed by magnet to states "NO" and "NC" exchanging likewise. FEATURES The side mounting float level switches ( LF series) are manufactured specifically for horizontal mounting in a tank or vessel. They work well as high or low level control. 1. Both Micro-Switch type and Reed Switch are available. The Micro-Switch type is usable even at an ambient temp. of 100 C max.. Liquid-contacting material made of or SUS316 and explosion proof model are available. 3. Mounting flanges are custom-specifiable. (JIS, DIN, ANSI). 4. A rich variety of float kinds to suit the different specific gravity (S.G.) of liquid. 55mm 55mm WIRING COM (C) NO (A) NC (B) REED SWITCH -- MICRO SWITCH

10 ANTI-ACID / ALKALINE PRINCIPLE When the solid polypropylene float is flooded by a liquid, its weight is reduced by the buoyancy of the liquid and the float moves upward. Thus, a permanent magnet that built in the float actuates the reed switch in the switch body to work the "NO" and "NC" exchanges.

13 IMPORTANCE FOR INSTALLATION 1. Corrosive application not available for / SUS316 materials.. The cable duct(s) must face downward to prevent moisture sipping in. 3. The float and extension rod must be inserted into a bin completely. 4. Be sure the liquid object's S.G. before installation. 5. The mounting hole must be size larger than the external diameter of float. 6. No to mount the devices near the bin's inlet or outlet.
