E18-D80NK Adjustable IR Infrared Obstacle Avoidance Proximity Sensor Switch

Description:

The E18-D80NK Adjustable IR Infrared Proximity Sensor Switch is a cost-effective, diffuse-reflective photoelectric sensor widely used for non-contact object detection, obstacle avoidance, and industrial counting applications. It integrates both the infrared transmitter and receiver into a single cylindrical unit, simplifying its use. A key feature is its adjustable detection range, which can be easily set from as close as 3 cm up to 80 cm using a multi-turn potentiometer on the back of the sensor. The sensor provides a digital switching output, making it simple to interface with microcontrollers like Arduino and other digital logic circuits.

Features:

Adjustable Sensing Range: Detection distance is fully adjustable from 3 cm to 80 cm via an onboard potentiometer.
Diffuse-Reflective Type: Operates by detecting the reflection of its own emitted infrared light off an object.
Digital Switching Output: Provides a simple ON/OFF digital signal, typically switching LOW when an object is detected and HIGH when clear (NPN-NO configuration).
Modulated IR Signal: Uses modulated infrared light to minimize interference from ambient light sources (like sunlight or indoor lighting).
Built-in LED Indicator: Includes an output indicator LED on the back of the sensor to visually confirm object detection.
Compact and Durable: Features a standard threaded cylindrical body (M18 diameter) for easy and secure panel mounting.
Wide Application: Ideal for robotics (obstacle avoidance, maze solving), automatic counting devices, and simple automation projects.
