Photoelectric Sensors are used for detecting the presence/absence of a target based on received light intensity, position, or color.
The LR-Z Series is capable of detecting objects based on position or contrast, allowing it to reliably detect metal targets, dark targets, transparent targets, contrast changes, etc. The series is housed in a rugged metal body and offers a simple one button teach. It has a range of up to 500mm (19.69") and offers hard wired, M8 connector, and M12 connector cable options.
The LR-Z's unique U.C.D. Function allows for stable detection of clear, metallic, or dark targets. This series can also detect purely based on distance, regardless of shape, color, or surface finish.
The IP68/69K rating means the LR-Z is ready for the roughest of factory environments. Wash-down, oil spray, and many corrosives are no match for the stainless steel body. Additionally, physical impact or even overtightening are not a concern because of the highly durable design.
The LR-T Series detects objects based on position and offers extended range to allow for flexible mounting. It is housed in a rugged metal housing, has a simple one button teach and is unaffected by color, surface finish or angle. This series has a range of up to 5m (16.4') and offers hard wired and M12 connector cable options.
The LR-T is designed to detect at long ranges while remaining highly stable. This is achieved due to the HS2 technology used, a combination of Time of Flight detection and a custom integrated circuit. Additionally, the interference prevention and Datum Function allow users to maximize this sensors capability in any situation.
The LR-T Series is simple to install and calibrate. Flexible mounting options, a visible beam spot, push button teach, and an easy to read display allow for quick setup. Even at long distances, constant feedback is provided with the LR-T's highly visible status indicator.
The LR-W Series can detect any difference in appearance (including color) and is in a durable metal housing. It has one touch calibration and can store up to 16 colors with an optional controller. This series has a range of up to 500mm (19.69") and offers hard wired and M12 connector cable options.
The unique technology in the LR-W series allows it to analyze the full light spectrum. This series can detect everything from surface finish differences to color changes that are hard to see with the naked eye.
There are three distinct sensors in the LR-W family. With specialties ranging from general purpose, complex targets, or fiberoptic integration, this series solves problems, not just applications.
The AI Series detects targets over an area when position is not fixed, reflection is unstable, or to differentiate products. By covering an area, targets that are misaligned or rotated can be easily detected. This series has a range of up to 160mm (6.30") and offers hard wired and M8 connector cable options.
The AI uses images to determine good parts from bad. After an image is registered, the target's brightness and shape are used to automatically determine which target features should be inspected during operation. This image-based method provides stable detection of targets that are difficult to handle when using conventional sensors with light intensity-based detection.
The AI Series can be used for a wide variety of applications. Examples include spring presence, label misalignment, screw tap presence, capacitor direction determination, and felt presence. In addition, the AI Series is capable of performing these detections over an area, which prevents errors due to variations in position or vibrations of targets.
The PR-M/F Series is the smallest metal photoeye in its class with an SUS316L stainless housing and offers both thrubeam and reflective options. Each model features a fixed field, meaning no calibration is required. This series has a range of up to 1.2m (3.94') and offers hard wired and M8 connector cable options.
The “hybrid structure” of the PR-M/F features an SUS316L stainless steel body that is also resin filled. The NEMA and IP rated enclosure means these units are highly resistant to oils, acids, and even alkaline detergents.
The PR-M/F Series is designed with Background Suppression and Automatic Cross Talk Prevention to provide highly stable detection. External light or movement will not interfere with the sensor.
The PR-G Series is a heavy duty general purpose photoelectric sensor in a metal housing with high power and easy trimpot adjustment. It has a range of up to 30m (98.4') and offers hard wired, M8 connector, and M12 connector cable options.
KEYENCE is known for durable sensors and PR-G is one of the most durable.
The PR-G Series has options powerful enough to blast 30m (98.4'). This power also benefits shorter range applications by being able to blast through dust, dirt, oil, etc.
The PZ-G Series is a general purpose photoelectric sensor in a resin housing with high power and easy trimpot adjustment. It has a range of up to 40m (131.2') and offers hard wired, M8 connector, and M12 connector cable options.
Reflective, Retro-Reflective and Thrubeam (breakbeam) types are all available in the PZ-G Series. These sensors have the power to blast over 130 ft and the sensitivity to detect even clear targets.
Simple trimpot calibration and light-on/dark-on capabilities are built into each PZ-G. Additional features like built-in alignment indicators make the PZ-G series very easy to use.
The PZ-V/M Series automatically increases power when dirty, is in a durable resin housing, has background suppression, and is unaffected by color or angle. It has a range of up to 10m (32.8') and offers hard wired, M8 connector, and M12 connector cable options.

A photoelectric sensor emits a light beam (visible or infrared) from its light-emitting element. A reflective-type photoelectric sensor is used to detect the light beam reflected from the target. A thrubeam type sensor is used to measure the change in light quantity caused by the target crossing the optical axis.
A beam of light is emitted from the light emitting element and is received by the light receiving element.
Both the light emitting and light receiving elements are contained in a single housing. The sensor receives the light reflected from the target.
Detection occurs when the light beam, emitted to the target, is reflected by the target and received.
The transmitter and receiver are separated. When the target is between the transmitter and receiver, the light is interrupted.
Detection occurs when the target crosses the optical axis between the photoelectric sensor's transmitter and receiver.
Both the light emitting and light receiving elements are contained in same housing. The light from the emitting element hits the reflector and returns to the light receiving element. When a target is present, the light is interrupted.
Detection occurs when the target crosses the optical axis between sensor head and reflector.
