Infrared Photoelectric Sensor | E18-D80NK Obstacle Avoidance

This E18-D80NK is an infrared sensor for obstacle avoidance in DIY electronics. It sends out an infrared beam to find objects from 3 to 80 cm away. This helps your smart car or robot move around without hitting things. You can easily set the detection range. Features and Benefits - Adjustable 3-80 cm detection range - You can fine-tune how far it looks for objects, good for different robot speeds and places. - NPN open-collector output - Sends a simple digital signal to microcontrollers like an Arduino. - Onboard indicator light - It turns on when it sees an object, which makes testing and fixing your project easier. - Infrared photoelectric technology - It works by sending and receiving light. This means the color of the object it detects doesn't matter. Applications - Building a smart car robot that can automatically drive around walls and furniture. - Making an automated system on a small assembly line to know when a part is in place. - Designing interactive art or displays that react when someone gets close. What It Is This Sensor Switch is an E18-D80NK Proximity Detector, designed to sense objects within a specific range without physical contact. It operates using a photoelectric detection method, meaning it uses light to detect the presence or absence of an object. This particular model is an infrared obstacle avoidance sensor, functioning as an optical sensor. It is an electronics module that provides a digital output when an object is detected. Key Uses & Applications This proximity sensor is suitable for various applications requiring non-contact detection. Its adjustable detection range, from 3 cm to 80 cm, makes it versatile for tasks such as automated gate control, object counting on a conveyor belt, or robotics for obstacle avoidance. As an industrial sensor, it can be integrated into systems where a reliable digital signal is needed to indicate an object's presence. The 5V operating voltage ensures compatibility with common electronics. How to Choose When selecting a proximity sensor, consider the required detection range; this model offers 3 cm to 80 cm. Evaluate the operating voltage, with this sensor requiring 5V. The output type, in this case digital, is crucial for integration with your control system. For testing a proximity sensor like this, you would typically apply the specified operating voltage and then pass an object through its detection field, observing the digital output change. Consider if a barrel sensor form factor is suitable for your mounting requirements.
