Photoelectric Sensors

Photoelectric sensors utilise light intensity-based detection principles to detect target presence/absence. There are several different types of photoelectric sensors, including reflective, retro-reflective, and thru-beam models. Photoelectric sensors offer a variety of benefits, including durability, application versatility, ease-of-use, and low cost.

LR-X series - Digital CMOS Laser Sensor

Digital CMOS Laser Sensor LR-X series

The LR-X Series is a remarkably small laser sensor capable of detecting targets based on position and is unaffected by colour, surface finish, or shape. Impressive durability is achieved with its food-grade stainles steel housing (SUS316L), high IP ratings, and guarded cable. Position changes as small as 0.5 mm are possible, along with automatic and real-time intensity adjustment to ensure stable detection on any target.

Features

Compact & Robust Design for Use Anywhere

Whether building a new machine or retrofitting an older one, the ultra-compact size of the LR-X Series makes it easy to integrate into any space. The metal housing and rugged design also ensure it will last in any environment.

Stable Detection of Any Target
Minimum Detectable Position Change: 0.5 mm

The LR-X Series detects targets based on position, not light intensity. This allows for stable detection of targets regardless of colour, surface finish, or shape. This allows the LR-X Series to be used in a wide variety of applications, including those with small position changes.

LR-T series - Self-contained TOF Laser Sensor

Self-contained TOF Laser Sensor LR-T series

The LR-T Series of reflective sensors represents a seamless fusion of innovative technology and robust functionality.

Catalogues Price

Features

Superior Detection Capabilities

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.

Easy to Use

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.

LR-Z series - Self-contained CMOS Laser Sensor

Self-contained CMOS Laser Sensor LR-Z series

Laser sensor capable of detecting targets based on both position and contrast (detectable distance: up to 500mm).

Catalogues Price

Features

Best Detection Ability in its Class

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, colour, or surface finish.

Durable & Long Life

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.

Simplified Operation

Simple setup and easy operation are at the core of the LR-Z's design. With a simple 1-touch teach, calibrating this sensor is straightforward and quick. A highly visible indicator and a 7-segment display make this sensor very easy to use.

New feature U.C.D. Function Distinguishing a Target From a Background Using the Distance and Received Light

The sensor first registers the distance to the background and the received light, which are used as reference, and then detects the target by sensing that the distance or received light differs from the registered reference when a target comes into the detection area. With the background, stable detection of target is ensured even if the target is a complex shaped object, has changes in colour and surface condition, or is a thin object with a small height difference.

Features

Sensitivity Setup and Display Standardisation at the Touch of a Button

Easy configuration

By standardising the received light intensity display of multiple sensors to “100” and “0”, it is easy to tell where an error has occurred because the sensor will not return to the original display value of “100” or “0”.

The sensor where the error occurred is identifiable at a glance.

Electric Wire Cable Allows for Rejoining

Because the sensor head cable is a simple power cable, it can be extended to the desired length. By soldering or using a metal connector, it can be extended to a maximum of 10 m (32.81').

Joining fibreoptic sensors

The light intensity is attenuated by approximately 90% at the joining surface.
With the PS-NEO, no light attenuation occurs even when cables are rejoined.
