The E18-D80NK is a reliable and widely used infrared proximity sensor that detects objects without physical contact. Designed with an adjustable detection range, it’s ideal for obstacle detection, object counting, robotics, and automation systems. It uses infrared light reflection to detect objects within its sensing range and provides a digital output signal.

Key Features:

• Adjustable Sensing Range – Detects objects from 7cm to 30cm
• Non-Contact Detection – Uses reflected infrared light for obstacle sensing
• Digital Output (High/Low) – Easily interfaced with Arduino, ESP32, STM32, etc.
• Built-In Indicator LED – Shows when an object is detected
• Easy Installation – M18 threaded cylindrical body with included mounting nuts
