E18-D80NK distance sensor is an optical sensor that uses infrared to detect objects in front of it in the range of 3-80 cm. The operating range is regulated by a potentiometer. The sensor has two rings on the housing to facilitate installation in the opening. Specification: - Supply voltage: 5V - Current consumption: <100 mA - Measuring range: 3 - 80 cm - Range (range) adjustment: YES (potentiometer) - Optical indication: LED lights up when detected - Response time: less than 2 ms - Reverse polarity protection: YES - Working temperature: -25 ° C to +55 ° C - Type of output signal: digital (low level when an object is detected, no object - high level) - Diameter: 18 mm - Sensor length: 68 mm Connecting the sensor: - brown: power supply + 5V - blue: GND ground - black: digital output OUT (after object detection - low level, normally - high level) https://elecena.pl/product/22604379/e18-d80nk-adjustable-proximity-sensor-3-80cm-arduino 2023-02-22 https://elecena.pl/product/22604379/e18-d80nk-adjustable-proximity-sensor-3-80cm-arduino 2025-10-29
