OMRON E3S-AT61 2M Built-in Amplifier Photoelectric Sensor (Medium Size)(Through-beam Sensors)(Vertical)(Pre-wired)(Sensing Distance 7m) NN

Photoelectric sensors are used to detect the absence or presence of an object within a specific area. They detect the objects through a variety of sensing modes by emitting a visible or infrared light and waiting for a response. Advanced application photoelectric sensors can detect color, contrast, distance, luminance and even area and dimension, but we will be focusing on the simpler universal sensors. These Datalogic S100 Universal Miniature sensors are capable of the three primary target detection modes: diffused, through-beam and retro-reflective. In addition, there are variations of these modes which allow for fixed focused detection and background suppression. Through-beam, also known as opposed mode, is the most reliable mode available for detection. It is also the only mode in which the emitter and receiver aren’t housed in the same unit. The emitter releases a light beam which
