Distance positioning sensor achieves new levels of accuracySick UK is launching its next-generation laser distance measurement sensor, DL100 Hi, achieving best-in-class levels of accuracy over greater distances for positioning and control in fast-moving environments.

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

There is a choice of three measuring ranges to suit customers’ applications (0.15–100mm, 0.15–200mm and 0.15–300mm) with a positional accuracy of up to +/-2mm and repeatability of up to +/-0.5mm. The DL100 Hi is the first sensor to utilise a new modular platform for SICK distance sensors, offering the customer flexibility and interchangeability within a common mechanical and electrical design. A variety of feedback interfaces are supported including SSI, RS422 and Profibus. Industrial Ethernet versions will be available from mid-2012 onwards.

With its IP65-rated compact metal housing, the DL100Hi is described as reliable and robust. It achieves a Mean Time Between Failures (MTBF) of 100,000 hours – double the lifetime of most 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 SpeedConTM connector technology with a 3D alignment capability which makes fine adjustment easy and cost-efficient.

Sick product specialist Darren Pratt says: “The technology advances achieved with the DL100 Hi are the culmination of more than 20 years’ of development in laser positioning and automation control at SICK. The result is a product which is the most accurate in its class.

“As a result of this improved performance, operators can achieve 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.”
