With these Separate-amplifier Sensors, the light from the Amplifier is transmitted through a fiber to enable detection in narrow places, other locations with limited access.

Photoelectric Sensors detect photo-optical workpieces. OMRON provides many varieties of Sensor, including diffuse-reflective, through-beam, retro-reflective, and distance-settable Sensors, as well as Sensors with either built-in or separate amplifiers and Fibre Units.

These Sensors can be used to measure distances and heights. A wide variety of models is available, including Laser Sensors, LED Sensors, Ultrasonic Sensors, Contact Sensors, Eddy Current Sensors, and more.

Vision Sensors/Machine Vision Systems analyze images to perform appearance inspections, character inspections, positioning, and defect inspections.

Code Readers can read 2D codes or bar codes and are available in installed or hand-held models.

Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.

These Optical Sensors provide a compact, low-cost method to detect workpieces. Many models are available, including Slot-type Sensors (through-beam) for non-modulated or modulated light, Reflective Sensors, and Sensors with separate emitters and receivers.

Rotary Encoders measure the number of rotations, the rotational angle, and the rotational position.

Ultrasonic waves are used to enable stable detection of transparent objects, such as transparent films, glass bottles, plastic bottles, and plate glass, using Through-beam or Reflective Sensors.
