Features: 100% brand new and high-quality. It adopts 304 stainless steel and 316L material,very durable. It can work at the temperature as high as 120℃. 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: 0.5-1 A Material :SUS304 & SUS316 Operating temperature:0 ~ 120 ℃ Maximum temperature tolerance 120 ℃ Working Pressure :1 Mpa Maximum withstand pressure :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 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. STAINLESS STEEL FLOAT LEVEL SWITCH: The float is made of all stainless steel 304, and the circlip is 316L. The stroke of the float is 10 mm, that is, the control range is 10 mm. If the control range is required to be large, two combinations, one long and one short can be installed. HOW TO WORK: By using a magnet to sense the reed switch. Float switch is mainly composed of a magnetic spring switch and a float. There are magnetic materials in the float. When the float moves up and down with the water level, it will touch the magnetic spring switch to detect the liquid position WIDELY APPLICATION: Float switch can be used for water heating equipment such as water dispenser, water heater, humidifier, etc. It also can be used for water tower, drainage pool, water tank, culture pond, etc PLEASE NOTE: Because the current that the switch can carry is much little(Low pressure 0.5A, high pressure 1.5A), you must use a relay or contactor when it is connected by a load, relay or contactor are not included here.
