Item Type: Non Contact Liquid Level Sensor <br>Material: PC <br>Model: XKC Y21 NPN <br>Current Consumption: ±8mA <br>Output Mode: NPN <br>Response Time: 500mS <br>Ripple And Noise Voltage: <1000mvpp <br>Liquid Level Accuracy: ±3mm <br>Environmental Certification: ROHS 2.0 <br>Input Voltage: DC5V <br>Output Current: ≤100mA <br>Operating Ambient Temperature: -20 to 75℃ <br>Sensing Thickness (Sensitivity) Range: ≤5mm <br>Safety Standard Certification: CE<br>1、Various Parameters: The noncontact level sensor has NPN output, 500mS response time and DC5V input voltage. <br>2、Corrosion Resistance: The level sensor will not be corroded by strong acid and alkali and other corrosive liquids, and will not be affected by scale or other sundries. <br>3、Liquid Level Memory: The sensor has intelligent liquid level reference adjustment and liquid level memory function, liquid level status display mode, and can realize multiple points of series connection. <br>4、Pure Electronic Circuit Structure: The liquid level sensor is accurate and stable in detection, pure electronic circuit structure, non mechanical working mode, stable performance. <br>5、Usage Scenario: The noncontact level sensor is suitable for use on the outer wall of non metallic pipes without direct contact with the liquid.Cautions. <br>1. Double sided adhesive made of foam wool must not be used. <br>2. The container material must be insulating material. <br>3. Try to use a uniform material without air interlayer, no air bubbles, not absorbent, the dielectric constant does not easily change the material for the container.1 x Water&nbsp;Level&nbsp;Liquid&nbsp;Sensor
