Principles of operation. • Photoelectric sensor is a generic name for sensors which detect an object by using light. The optical signal transmitted from the emitting part of the sensor is modified by being reflected, transmitted, absorbed, etc., by the sensing object and is then detected by the receiving part of the sensor to
Photoelectric Sensors Theory of Operation. A photoelectric sensor is another type of position sensing device. Photoelectric sensors, similar to the ones shown below, use a modulated light beam that is either broken or reflected by the target. The control consists of an emitter (light source), a receiver to detect the emitted light,

This site provides information useful for people involved in manufacturing to select sensors. Photoelectric Sensors detect targets based on the change in the intensity of reflected or interrupted light. This page introduces their principles, major types, and selection points according to applications. This site is operated by

A sensor is made up of an irradiating element, a particular type of light (usually infrared, red or green) and an element photosensitive to the irradiated light.
Photoelectric www.fargocontrols.com. 732 389-3376. 51. OPERATING PRINCIPLES FOR PHOTOELECTRIC SENSORS. These sensors use light sensitive elements to detect objects and are made up of an emitter (light source) and a receiver. Four types of photoelectric sensors are available. Direct Reflection - emitter and
Whereby the light beam is extremely fine and parallel over the entire operating range. This advantage is, above all, used when the smallest of objects have to be detected along the entire operat- ing range. Regardless of the physical principle, all retroreflective photoelectric sensors from SensoPart have a so-called polarisa-.
