A Laser Through Beam Sensor with the Edge

The Conventional infrared though beam sensors found in many manufacturing installations can generate unexpected malfunctions that could lead to many hours of investigation and maintenance to resolve.  Panasonic design engineers embraced this situation as a challenge, find a way to simplify this investigative process and make life easier for the operators and engineers involved in the tasks at hand, ultimately saving companies time, money and a lot of hassle!

Designed for use on manufacturing and processing lines, the HG-T Series Laser Through-beam Sensors feature a built-in self-monitoring function that diagnoses the current operational state and notifies the user when readjustment of established settings have drifted and when maintenance is required. The sensor determines its status and indicates Normal, Notification, Caution or Fault via its controller. When not in its normal status, the sensor identifies the cause of the problem and the corrective measures required, reducing equipment downtime and maintenance workload.

Finding the Edge

A HG-T Laser Through-beam Sensor installation, which consist of an emitter,  receiver unit and a controller, produces a flat, belt-shaped laser beam with a height of 10 mm which is ideal for tasks such as checking the contours of an edge, shaft diameters or the inside diameter of a product. The sensors have a sensing range of 500 mm, achieving a repeatability of < 1µm and have a linearity of less than ± 12µm over their measurement range, meaning that they are suitable for a wider range of applications than those infrared sensors with a shorter sensing distance.

Quick to install, the sensor heads are equipped with a beam alignment function to help speed up commissioning. Easy to set up by simply plugging the sensors into the controller unit which then automatically detects whether the emitter and receiver are connected correctly.

Available in two different sensor head versions, both with the same capabilities and only differing in their physical dimensions. The receiver of the slim version is 10 mm narrower than the standard model making it suitable for installations with very limited space where the standard version would perhaps be too large.

View the Range


UC18GS Series: one compact sensor, a multitude of applications

Using modern technological capabilities, the UC18GS series will optimise your application. With functionalities such as interference target suppression, adjustable sound beam width, automatic synchronisation, small dead bands, IO-Link, infrared interface, and push buttons, the UC18GS series offers an unparalleled range of features and adjustment options all in a single device.

UC18GS series: Interference Target Suppression

Interference Target Suppression

With built-in interference target suppression, the UC18GS ultrasonic sensor range adapts to the application settings to optimise and increase process reliability. The intelligent suppression is capable of detecting precisely even if a suppressed component is in the target range.  What’s more, any possible interference from other machine parts can easily be suppressed using the integrated software without affecting everyday use.

UC18GS series: Adjustable Sound Beam Width

Adjustable Sound Beam Width

Thanks to the small dead band and adjustable sound beam width, the UC18GS ultrasonic sensor is able to perform without faults in a range of applications. To ensure precise and accurate measurements, the sound beam can be adjusted and narrowed without affecting the range. Perfect for installation to your existing application!

UC18GS series: Automatic Synchronisation

Automatic Synchronisation

Often when using several sensors in close proximity they interfere with each other; this, however, is no problem for the UC18GS series. Equipped with an automatic synchronisation feature, the UC18GS range can easily sync with multiple sensors without parameterisation. Using their synchronisation input up to 10 sensors can be synchronised together. The UC18GS range has 3 different synchronisation modes: common, multiplex or externally triggered.

Extensive Programming Options

Extensive Programming Options

Whether it’s traditional pushbuttons or interfaces like IO-Link or IrDA, the UC18GS range of ultrasonic sensors gives the user a wide range of programming choices. While IrDA interfaces can provide live data access for maintenance or analysis purposes, IO-Link provides easy setup and allows detailed configuration for any application. The output configuration, as well as the sound beam width can be set directly on the sensor using the programming buttons.

In addition, the IO-Link interface allows for seamless integration into Industry 4.0 applications.

Series UC18GS: One Technology—Limitless Versatility

No two applications are the same with each providing its own unique demands on a sensor. Designed to be highly robust and technologically advanced, the UC18GS is perfect for complex tasks in any environment, whether that’s the detection and identification of objects or filling levels.

Adaptable Level Measurement in Confined Spaces

The UC18GS series can reliably detect the fill level of liquids and granules, regardless of colour or other physical properties. With the adjustable cone-shaped sound beam width, even a small opening in the tank cap is suitable for installation.

In the case of irregular or moving surfaces, the sensor determines an average value and thus indicates the actual level —instead of a potentially distorted punctual value. Objects such as support struts in the measuring field are suppressed by software (PACTware) to reduce interference and to return precise results. Regardless of the sound beam radius, the range of the UC16GS series is not affected and the level is always reliably detected.

Fail-Safe Bottle Detection in Filling Machines

Ideal for reliably detecting the presence of bottles in the end positions on a production line, the UC18GS series can detect an object with varying contours and position deviations. Instead of taking a point-by-point measurement, the sound beam hits the surface of the container over a wide area making its shape, colour and texture irrelevant. The physical buttons on the UC18GS series mean the output configuration and the sound beam radius can be set with ease.

With the IO-Link interface, comprehensive parameters can be set via the controller without physical access to the sensor. This leads to faster commissioning time and removes the need for re-parameterisation if the sensor needs to be changed.

POG 83 rotary encoder

Baumer’s POG 83 Series Rotary Encoders, Built for a life at Sea

Rotary encoders, or shaft encoders as they are often referred to as, are a popular engineering choice when it comes to location, speed and distance monitoring of an axle or a shaft that is located within a mechanical system. Typical encoder applications include industrial control systems, robotic production lines and conveyors, cranes, radar systems and more. Typically, Rotary Encoders come in two particular variants, these being absolute and incremental, absolute encoders provide details of a shaft’s current location, incremental encoders monitor the angular motion or the position of a shaft.

Electro-mechanical in nature, angular position and motion data from the monitored shaft is detected and converted into an analogue or digital signal for interpretation by other aspects of the installations control system to gauge speed, location, distance and act upon that information.

When it comes to motion, speed and distance monitoring in demanding conditions such as those found at sea, you will need a Rotary Encoder that has been specifically designed to resist and ignore the harsh and demanding environmental it is destined to function in.
