The MD17/73 operates on the thru-beam (opposed) photoelectric principle, where an infrared transmitter and receiver are separated. The modulated 950nm light beam provides immunity to ambient light interference up to 10,000 lux, ensuring reliable object detection even in variable lighting conditions. The sensor’s fast response time (≤3 ms) and 150 Hz switching frequency enable high-speed counting and positioning tasks on fast-moving production lines.
Engineered for industrial durability, the sensor features a robust ABS housing with an IP67 rating, making it resistant to dust ingress and temporary water immersion. It includes built-in protection against short-circuits and reverse polarity, safeguarding both the sensor and the connected control system. The compact design and dual mounting options (M18 threaded front or side) offer flexible integration into machinery, conveyor systems, and automated handling equipment.
