E18-D80NK IR Proximity Sensor - Input voltage: 5V DC - Current consumption: > 25mA (min) ~ 100mA (max) - Dimension: 1.7cm (diameter) x 4.5cm (length) - Cable length: 45cm - Detection of objects: Transparent or Opaque - Diffuse reflective type - Sensing range: 3cm to 80cm (depends on obstacle surface) - NPN output (normally high) - Environment temperature: -25 °C ~ 55 °C. E18-D80 IR Sensor is widely used in robots to avoid obstacles, industrial assembly lines, Reverse Car Parking, and many other automation applications. The detection range can be adjusted according to the application using the multi-turn screw that is located at the back of the sensor. The switching signal output changes according to the obstacle detection. It remains high when no obstacles and changes to low when there are obstacles. A red LED is placed behind the probe that turns high whenever an obstacle is detected. The E18 sensor operates on 5V and consumes around 5mA to 30mA current without any load. Price 600 Birr
