1. Non contact liquid level sensor, suitable for the outer wall of non-metallic containers without direct contact with liquids, will not be corroded by corrosive liquids such as strong acids and alkalis, and will not be affected by water. The influence of dirt or other debris. Can support high and low level output, NPN, PNP signal output (please specify with the manufacturer when selecting).2. Accurate and stable detection, capable of detecting boiling water level.3. Pure electronic circuit structure, non mechanical working mode, stable performance and durability.4. High stability, high sensitivity, strong anti-interference ability, not affected by external electromagnetic interference. Special treatment has been made for power frequency interference and common mode interference to be compatible with all 5-24V power adapters on the market.5. Strong compatibility, able to penetrate various non-metallic materials such as plastic, glass, ceramics, etc., with a sensing distance (container wall thickness) of up to 20mm; liquids, powders, and particles can be detected.Open electrode output method with a wide voltage range (5-24V), suitable for connecting various circuits and product applications.Current consumption: 5mAResponse time: 500mSRipple requirement: Less than 200 mVWaterproof performance: IP67Sensing thickness (sensitivity): Range Less than 20mm (container wall thickness)Terminal definitions: brown (VCC), yellow (signal output), black (signal selection terminal), blue (GND)Wire length: 500MM (± 10MM)Working temperature: -20~80 ℃Liquid level accuracy: ± 1.5mmColor: As shownMaterial: PC-V0Package Contents:4 x XKC-Y25-V Water Tank Level SensorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
