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

Maintain faultless obstacle avoidance tracking in your automated machinery using the premium E18-D80NK Adjustable IR Sensor. Explicitly optimized for wide-angle non-contact proximity detection, this industrial-grade photoelectric switch delivers a versatile adjustable tracking distance spanning 3 to 80 cm. Built into an M18 threaded cylindrical chassis with an integrated rear potentiometer, it allows technicians to fine-tune trip ranges on-the-fly to cancel out ambient light background interference. The internal modulated light array outputs a clean digital NPN signal to communicate obstacle states instantly without processing delays. It serves as the definitive component choice for robotics competition chassis, automated assembly line counting tracks, conveyor belt sorting modules, and smart touchless washroom appliances paired with Arduino, ESP32, or PLC networks.
