SEN-HZ06S water flow sensor, 6mm quick-plug self-locking, easy to install, Hall working principle, pulse signal output, red is positive, black is negative, yellow is pulse signal, can be used as a water flow switch, food grade POM material, It can be used in filter manager, direct drink machine, water purifier, coffee machine, energy water machine, beer machine, wine cooler, mechanical equipment, , laser equipment, toilet and so on. The pluse signal water flow sensor is widely applied in industrial equipmen, agricultural equipment and household electrical appliances in the future. It includes a plastic body housing, a water rotor, and a hall-effect sensor, PCB electronics board Our water flow sensors with POM materials can be used to water dispenser, water purifier, coffee machine, wine cooler, beer machine, monitor liquid flow rate in water machine, water heater, coffee machine, vending machine, water meter testing machine and the like. Working performance : When the water flows through the rotor, then rotor is rolled Its speed changes with different rate of flow. Then the magnetic rotor make reaction to Hall sensor, the hall-effect sensor outputs the corresponding pulse signal Product Details: Flow Range: 0.25-3.0L/min Connection: 6MM diameter intutation Voltage: DC4.5-18V Certificate: food grade Pressure performance: less than 1.2MPA Line specification and install direction: could be Customized Water temperature: less than 60 Insulated resistor: >100M Electrical strength: AC500V, 50Hz Output level: rated DC5V, high level 4.3V, low level 0.5V Pulse duty cycle: pulse duty cycle 50% Cumulative flow conversion: 1L water = 11446pulse Lead Way: Red IN connect the anode Yellow OUT signal output line Black GND connect the cathode Package includes: 1PC Water Flow Sensor
