About this product
The E18-D80NK is a digital infrared proximity sensor that uses an IR LED and receiver to detect an object within an adjustable distance. Its threaded body allows easy mounting and fine distance adjustment. It is commonly used for counting objects on production lines, obstacle avoidance on robots and stopping at a set position.

How do I wire the E18-D80NK?
Connect brown to +5 V to 36 V, blue to GND, and black to the signal input. The output is an NPN open-collector that pulls low when an object is detected, so use a pull-up resistor (for example 10 kΩ) to the logic supply or the MCU internal pull-up.
Can I read its output with an ESP32 (3.3 V logic)?
Yes. Power the sensor from 5 V, but pull the output up to 3.3 V with a resistor, so the signal stays within the ESP32 GPIO voltage range. Read the pin as HIGH when idle and LOW when an object is detected.
