Product Specification
| Description | SOP-16 Float, Level Sensors RoHS | Mfr. Part # | SCW8916B |
| Package | SOP-16 | Model Number | SCW8916B |
The SCW8916 is a 4-channel high-sensitivity capacitive water level detection IC capable of accurately detecting changes in water and other liquid levels from a distance of 2mm. It features industrial-grade specifications with 4KV EFT and 6KV contact ESD capabilities, and can pass 3V CS testing, making it an ideal choice for electronic liquid level detection solutions. It is well-suited for water-related home appliances and electronic products such as water dispensers, purifiers, coffee machines, kettles, dishwashers, and ice makers.
