Non-contact liquid level sensor is applicable to non-metallic containers without direct contact with the liquid, not affected by scale or other impurities.Intelligent liquid level benchmark adjustment and level memory function, liquid level display mode, can achieve multi-point series connection.Electronic circuit structure rather than machinery ensures stable performance, durability and a long service life.High stability, high sensitivity, strong anit-interference ability make sure it won't be affected by electromagnet, special designed to deal with power frequency interference and common mode interference.color: Whitematerial: plasticCompatible with most 5 ~ 24V power adapter.Strong compatibility through a variety of non-metallic material containers, such as plastic, glass, ceramics etc, with a 13mm or more induction distance.Testing is accurate and stable and boiling water level can be detected. Liquid, powder, particles can all be detected.Adjustable sensitivity.Specifications:Model: XKC-Y25-PNPOutput: NPNInput Voltage (InVCC): DC 5~24VCurrent: 5mAOutput Voltage (high level): InVCCOutput Voltage (low level): 0VOutput Current: 1~100mAResponse Time: 500mSOperating Temperature: 0~105°Induction Thickness (sensitivity): 0~13 mmCommunication: RS485Humidity: 5%~100%Package Contents:1 x Liquid Level SwitchOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
