Siemens Automation and Drives (A&D) presents new electronic components in the Delta switches and socket outlets range for the retrofit market in the area of lighting and shutters. The new products include universal dimmer and shutter control inserts, conventional and wireless operator pushbuttons, and a battery-operated wall-mounted transmitter.
The "sys universal dimmer insert" is suitable for all types of lighting to 420 watts/volt-ampere connected load. The dimmer can be easily retrofitted with two-wire connections. It is characterized by a lamp-saving soft start and can be programmed to switch on to a predefined brightness value, and also features electronic overtemperature and short-circuit protection.
With the "sys shutter control insert", shutters and roller shutter motors can be controlled up to a connected load of 1,000 volt-amperes. Group and central controllers can be implemented by combining several shutter control inserts using the extension unit inputs. As well as enhancements such as 24-hour automatic operation in conjunction with the Delta "wave shutter" pushbutton, the sys shutter control insert offers a "wind alarm" safety function if a wind sensor is connected to the OPEN extension unit input.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
