Features: Brand new and high-quality. It adopts 304 stainless steel and 316L material,very durable. The premium reed switch of it is come from Japan and US,very reliable. It can withstand 5Mpa at most which makes it can work at most environments. It can work in AC 0-220V,and DC 0-200V which makes is suitable for most power source. Specification: Working voltage :0 ~ 220 (V) Working current :0.5 A-1 (A) Material :SUS304 & SUS316 Operating temperature:0 ~ 120 ℃ Maximum temperature tolerance: 120 (℃) Working Pressure :1 (Mpa) Maximum withstand voltage: 5 (Mpa) Maximum power: low voltage: 10W High voltage: 50W Maximum switching current: low voltage: 0.5A High voltage: 1.5A Package List: 1*Liquid Level Sensor Note: 1. As different computers display colors differently, the color of the actual item may vary slightly from the above images. 2. Please allow 1-3mm differs due to manual measurement. Attention: Floating ball is all stainless steel 304 material, clip spring is 316L material. Low voltage refers to the floating ball switch can be used in 0-110V DC voltage circuit. High voltage means floating ball switch can be used in AC 0 ~ 220V, DC 0 ~ 200V line. High temperature is to point to float ball switch can long-term withstand temperature 120 degrees. High temperature and high pressure is white silica gel high temperature line, low pressure is common black line Floating ball switch can not directly control solenoid valve or high-power relay, AC contactor and so on.Add a small relay to make the transition. Floating ball travel 10mm, that is, the control range 10mm, if the control range can be large 2 combinations,1 long and 1 short installation. Usage: Products can be used in water dispensers, water heaters, solar energy, air conditioners, humidifiers, bathroom equipment, sales machines, fuel tanks, water towers, liquid level control of chemical liquids, kitchen equipment, water heaters and other water heating equipment anti-dry water level sensors. It has broad application prospects in automobiles, industrial equipment, agricultural equipment, and household appliances. .
