E18-D80NK Adjustable IR Sensor Proximity Switch (3–80cm Range)

The E18-D80NK NPN-NO Adjustable IR Sensor Proximity Switch is a high-performance diffuse reflective infrared sensor that integrates both an IR transmitter and receiver into a single compact unit. With its adjustable detection range from 3cm to 80cm, the sensor delivers flexibility for a wide range of electronic and industrial applications. Operating on 5V DC, the sensor provides a digital output signal that remains HIGH when no object is detected and switches LOW when an obstacle enters the sensing range. Its output indication LED ensures easy alignment and real-time detection feedback. The E18-D80NK adjustable IR sensor is engineered to minimize the influence of object color and surface reflectivity, ensuring stable and accurate detection. With TTL-compatible output, no external control circuitry is required, making it a cost-effective and user-friendly solution for automation projects. Manufactured with industrial-grade quality, this sensor is widely used in robot obstacle avoidance, conveyor automation, interactive displays, and security systems.
