This site is a resource for those in manufacturing who select sensors. This page introduces their principles, major types, and how to select based on need. A photoelectric sensor , or photo eye, is an equipment used to discover the distance, absence, or presence of an object by using a light transmitter, often infrare and a photoelectric receiver. There are three different useful types: opposed (through beam), retro-reflective, and . 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 Fiber Units.

Photoelectric sensors use a beam of light to detect the presence or absence of an object. Our photoelectric sensors satisfy applications found in many industries, . This article is focused on photoelectric sensors and defines what they are, their advantages and some basic modes of operation. The basic function of each is to detect the presence or absence of objects, or measure distance to the object. Within manufacturing they help to keep processes running smoothly by providing real time information which can be fed back to the central processing units.

It is also referred to as photo eye. These devices provide non-contact detection of parts over longer distances than other sensing modes such as inductive or capacitive . They use an infrared beam from. This technology is used to identify size and contrast of an object. The optical signal transmitted from the emitting part of the sensor is modified by being reflecte transmitte absorbe etc. Versatile and highly sensitive, Contrinex photoelectric sensors deliver long- distance, non-contact detection of metallic and non-metallic targets, accommodating variable target color and surface finish.

High-frequency switching circuitry senses small, fast-moving objects, even against non- contrasting backgrounds. The complete line of self-contained and amplifier separated photoelectric sensor solutions from Panasonic are anything but basic. We offer some of the smallest photoelectric sensors in the world for unmatched simplicity and versatility.

Background suppression, foreground suppression and background evaluation models are available. NX-photoelectric sensor.
