With a corrosion-free build and advanced magnetic technology, this normally open type sensor features a 2-meter cable and operates effectively within a voltage range of 2 to 12V DC. Ideal for both DIY enthusiasts and professional applications, it supports a maximum switch current of 5A, making it a reliable choice for various water management needs. ## Description Product Description Wide Range of Liquid Level Sensors How sensor works..?? A magnetic float sensor works by using a magnet inside the float and a sealed reed switch placed inside the sensor body. As the water level rises or falls, the float moves up or down along the guide rod. When the float reaches a set level, the magnet activates the reed switch without any physical contact. This change in switch state is used to detect the water level or control a pump, ensuring accurate, reliable, and corrosion-free operation. Corrosion Free Material A magnetic float sensor is corrosion free because it has no direct electrical contact with water . The sensing is done using a sealed reed switch placed inside a protective housing, while the float contains a magnet that activates the switch externally. Made With Best Quality Reed Switches Made with best-quality reed switch for high reliability and long service life. The hermetically sealed reed switch ensures precise and consistent level detection without direct contact with water, offering excellent resistance to moisture, oxidation, and wear. Flexible Mounting Design The magnetic float sensor supports both upside mounting and downside mounting , allowing easy installation in overhead tanks, sumps, or water containers. Made with 100% pure copper wires Made with 100% pure copper wires to ensure excellent conductivity, lower power loss, and reliable long-term performance. High-quality copper wiring provides better current handling, improved efficiency, and enhanced durability compared to mixed or aluminum wires, making it ideal for continuous and safe operation. Review: Wonderful item 👌 - Got the product today. It was exactly same as described. Tested and installed. Wonderful item 👌👌 Working perfectly !!! Durability yet to know. Hopefully it will last long. As of now⭐️⭐️⭐️⭐️⭐️ Review: Innovative product to save water - Magnetic float switch to either indicate full tank or to control a pump (using a relay). Good product quality. The junction between wire and the switch could have been more robust. The stem which holds the magnetic float is thin and feels flimsy. Other than these issues, it's a good product. Works as described. Have fitted in my house' overhead water tank and connected it to an alarm. ## Features - Normally Open Type - Corrosion Free Material - Advance Magnetic Technology - Cable Length : 2 meter - Max Switch Current : 5A (DC), Max Switch Watt : 10W / VA, Ideal Operating Ratings : Voltage: 2 to 12V DC Current: 5 to 50mA DC ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | ALL ABOUT ELECTRONICS | | Manufacturer | ALL ABOUT ELECTRONICS | | Country of Origin | India | | Model number | FSNO-01 | | Colour | yellow | | Number of Memory Sticks | 1 | | Item Weight | 70 g | | Product Dimensions | 5.4 x 1.3 x 1.3 cm; 70 g | | Item model number | FSNO-01 | | Item Height | 1.3 Centimeters | | Item Width | 1.3 Centimeters | | Are batteries included? | No | ## Images ![Magnetic Float Sensor Switch (Water Level Sensor) for Water Level Controller NO Type - Image 1](https://m.media-amazon.com/images/I/714UBE1JPpL.jpg) ![Magnetic Float Sensor Switch (Water Level Sensor) for Water Level Controller NO Type - Image 2](https://m.media-amazon.com/images/I/51nx7xO7I6L.jpg) ![Magnetic Float Sensor Switch (Water Level Sensor) for Water Level Controller NO Type - Image 3](https://m.media-amazon.com/images/I/31TK7vDYQ7L.jpg) ![Magnetic Float Sensor Switch (Water Level Sensor) for Water Level Controller NO Type - Image 4](https://m.media-amazon.com/images/I/61P3Q3PbM8L.jpg) ![Magnetic Float Sensor Switch (Water Level Sensor) for Water Level Controller NO Type - Image 5](https://m.media-amazon.com/images/I/91KSV9gsbvL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wonderful item 👌 *by S***Y on 28 August 2025* Got the product today. It was exactly same as described. Tested and installed. Wonderful item 👌👌 Working perfectly !!! Durability yet to know. Hopefully it will last long. As of now⭐️⭐️⭐️⭐️⭐️ ### ⭐⭐⭐⭐ Innovative product to save water *by S***A on 19 July 2019* Magnetic float switch to either indicate full tank or to control a pump (using a relay). Good product quality. The junction between wire and the switch could have been more robust. The stem which holds the magnetic float is thin and feels flimsy. Other than these issues, it's a good product. Works as described. Have fitted in my house' overhead water tank and connected it to an alarm. ### ⭐⭐⭐⭐⭐ This kit is very simple to use as water level indicator *by H***T on 28 September 2024* I am using this kit with a DC operated calling bell connect in series supplied by 3v dc. It is fix to hang from the top of the water tank on the roof keeping the switch on and the bell will be rang when water level touch es the kit with allert you to Stop your motor. After using this I am not destroyed water uselessly. ## Frequently Bought Together - Magnetic Float Sensor Switch (Water Level Sensor) for Water Level Controller NO Type - Float Sensor Switch (Water Level Sensor) for Water Level Controller NC Type - Float Sensor Switch (Water Level Sensor) for Water Level Controller Both Side Sense --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/89479949-magnetic-float-sensor-switch-water-level-sensor-for-water-level](https://www.desertcart.tw/products/89479949-magnetic-float-sensor-switch-water-level-sensor-for-water-level) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-05-17*
