Positioning sensor achieves high accuracy

October 2019 Sensors & Transducers

SICK Automation’s next-generation laser distance measurement sensor, DL100Hi, achieves higher levels of accuracy over greater distances for positioning and control in fast-moving environments.

This high performance can help achieve cost and operating efficiencies in high-speed automated applications such as warehouse storage and retrieval and in distancing and collision prevention for overhead cranes.

With the DL100Hi, SICK has developed significantly-improved control loop technology to achieve faster and more accurate position feedback. The sensors’ data output supports applications with acceleration values up to 15 m/s2. As a result, for example, storage and retrieval systems can become more efficient – achieving shorter run times and more runs per hour.

The new sensor offers the choice of three measuring ranges to suit customer applications (0,15-100 mm, 0,15-200 mm and 0,15-300 mm). It is also the first to utilise a new modular platform for SICK distance sensors, offering users flexibility and easy interchangeability within a common mechanical and electrical design. A wide variety of feedback interfaces are supported including SSI, RS-422, Profibus and industrial Ethernet.

With its IP65-rated compact metal housing, the sensor is reliable and robust. It achieves a MTBF of 100 000 hours – double the lifetime of many standard laser sensors. Operators can therefore reduce downtime and the total cost of ownership.

Maintenance downtime is also minimised through the sensor bracket’s quick-release mechanism and SpeedConT connector technology with a 3D alignment capability that makes fine adjustment easy and cost effective.

“The technology advances achieved with the DL100Hi are the culmination of more than 20 years of development in laser positioning and automation control at SICK,” concludes product specialist, Mark Madeley. “As a result of its improved performance, operators can realise significant improvements in operating efficiency. At the same time, the sensors’ robustness and reliability reduce the risk of downtime and offer longer periods between replacement.”
