Photoelectric Sensors (Photoelectric Switches)

Photoelectric sensors detect objects by reflection or shielding of visible or invisible rays. Switches with built-in amplifiers and fiber switches are available. Azbil’s product line includes General Purpose Photoelectric Sensors with Self-Contained Amplifiers, Fiber Optic Photoelectric Sensors, and Wet Process Sensors and Fiber Units.

Azbil General Purpose Photoelectric Sensors with Self-Contained Amplifiers have integrated optical systems, amplifiers, and control circuits. We offer a wide variety of types, including thru-scan, diffuse-scan, and retroreflective.
Our Fiber Optic Photoelectric Sensors offer good usability and a high level of performance. The Amplifier Unit (HPX) and Optical Fiber Unit (HPF) combine to form a Fiber Optic Photoelectric Sensor.
Azbil’s Wet Process and Fiber units are specialized optical fiber sensors used primarily in the semiconductor and liquid crystal manufacturing process to detect the dropping of minuscule parts, detect parts for wafer mapping, and detect fluid leakage or the position of the surface of the liquid.

  • General-Purpose Photoelectric Sensors with Self-Contained Amplifiers

    Azbil General-Purpose Photoelectric Sensors with Self-Contained Amplifiers are highly reliable and easy to operate. They are available with various connection methods, long-distance detection, and a protective structure. We offer a variety of models, including thru-scan, diffuse-scan, retroreflective, and distance-measurement for harsh environment applications in wet processes.

  • Wet Process Sensors and Fiber Units

    Azbil’s Wet Process Optical Fiber Sensors specialize in detecting leakage or surface level of chemicals and pure water used for heat treatment, washing, or exposure processes in the manufacturing of semiconductor and LCD crystals, detection during wafer mapping, and detection of the dropping of an LED or other tiny part. Sensors are also used in many life sciences and bio-medical equipment applications. They not only feature a high level of detection performance but also save space, reduce adjustment workload, and are easy to maintain.
