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 Fiber Units.

Through-beam photoelectric sensors consist of an emitter and a receiver in separate housings. The emitter sends a beam of light to the receiver, which determines a target is present when the beam is interrupted. These sensors offer the longest …

Mar 17, 2025 · In this article, we will be talking about the three main types of Photoelectric Sensors: Through-Beam, Retroreflective, and Diffused. A Photoelectric Sensor is a device that uses light to detect the presence or absence of an object.

Thru-beam sensing is the most efficient sensing mode which results in the longest sensing ranges and highest excess gain. This high gain enables through-beam sensors to be reliably used in foggy, dusty and dirty environments.

Through-Beam Photoelectric Sensors Through-beam photoelectric sensors consist of an emitter and a receiver in separate housings. The emitter sends a beam of light to the receiver, which determines a target is present when the beam is interrupted. These sensors offer the longest sensing distances but require precise alignment.

Through-beam photoelectric sensors work by having a separate emitter and receiver. The emitter sends a light beam, and the receiver detects it. When an object interrupts the beam, the sensor triggers a response. These sensors are highly reliable for …

Photoelectric sensors with a single transmitter and single receiver are placed in opposite to each other. The transmitter sends an infrared beam to the receiver. When an object interrupts the light beam, the output is activated.
