te.com HORIZONTAL LIQUID LEVEL SENSORS LS Series High- or low-level switching N.O./N.C. SPST or SPDT outputs Mounted on the side wall of a tank Certified reed switch (UL component listed) Choice of several non-reactive wetted materials Many different configurations available Features  Voltage rating up to 250VAC  Current rating up to 1.0 amp  Compact design and low profile  Optional cable lengths  Includes mounting hardware Applications  Water and fuel storage tanks  Full and/or empty detection  Pump on/off controls  Marine bilge and ballast tanks  Flood detection and prevention  Coolant level indication  Livestock watering tanks  Irrigation systems  Water treatment plants  Waste water tanks The LS series of point liquid level switches demonstrates a high degree of reliability due to the use of non-reactive wetted components and a unique reed switch designed specifically for level sensing applications. The sensor utilizes a moving float with an embedded magnet to activate a reed switch located in the sensor body. As the liquid level raises the float, it moves into close proximity to the reed switch and actuates it to give an open contact or closed contact switch indication. The reliability of this sensor results from a very simple operating principle, a single moving part, media compatible wetted materials, and a unique reed switch design that has a UL recognized component certification. The sensor mounts into the side wall of a liquid storage tank using either a 1/2” NPT or M16 x 2.0 threaded fitting. The M16 mount is available in either an internal or external configuration. The output is a simple N.O. or N.C. SPST, or SPDT reed switch that utilizes Ruthenium contact points for reliability. Changing from a N.O. output to a N.C. output is done by rotating the switch 180° in the mounting hole. This change can be done in the field. Electrical outputs are a single pair of wires with PVC insulation and optional lengths of 0.5 m or 2.0 m.  Chemical storage and processing CLICK HERE › CONNECT WITH A SPECIALIST TE CONNECTIVITY SENSORS /// LS SERIES 10/2020 Page 1 LIQUID LEVEL SWITCH LS SERIES Absolute Maximum Ratings (1) Parameter Min Max Units DC contact voltage (SPST) 100 V DC contact current (SPST) 1.0 A RMS contact voltage (SPST) 250 V RMS contact current (SPST) 1.0 A DC contact voltage (SPDT) 170 V DC contact current (N.O.
