The E18-D80NK Adjustable IR Proximity Sensor combines both transmitter and receiver in a single photoelectric switch module. It features an adjustable detection range from 3 to 80 cm, allowing customization based on application requirements.

Compact, cost-effective, and easy to use, this sensor is ideal for obstacle avoidance in robotics, interactive systems, industrial automation, and more.

The output signal changes based on object detection—remaining high when no obstacle is present and switching low when an object is within range. A bright indicator light behind the sensor probe helps visualize the active detection area.
