The E18-D80NK Adjustable Infrared Sensor Switch (3–80 cm) combines both transmitter and receiver in a single photoelectric sensor unit. Its detection distance is adjustable, allowing precise control within a range of 3 to 80 cm, making it suitable for various applications.

Compact, affordable, and easy to integrate, this sensor is ideal for obstacle avoidance in robots, interactive systems, industrial automation, and more. The output signal varies based on object presence—HIGH when no obstacle is detected and LOW when an object is within range.

A visible indicator light behind the probe assists in identifying the sensor's active detection zone.
