Determining distances is one of the most common metrological applications in automation technology. The market supplies many solutions, yet not every technology is ideal for each application. Pepperl+Fuchs’ new distance measurement sensor, VDM28, is setting standards in this dynamic field.
With a measuring range up to 8 m, the sensor reliably detects distances in diffuse mode. The groundbreaking Pulse Ranging Technology (PRT) measuring principle is applied.
For the first time, a red laser is used as sender. It emits short light pulses to determine distance by measuring the time of flight of the reflected pulses. The high visibility also enables optimal alignment. This is an innovative combination for PRT sensors and ensures perfect performance and convenience through the unique advantages of this technology. In contrast to other procedures, measuring accuracy is independent of the object surface. The measuring principle eliminates issues such as detection of “phantom objects” or measuring fluctuations due to ambient conditions.
The device can be operated as a standard diffuse sensor or as a distance measurement sensor. The switching threshold settings are entered using simple pushbutton programming via Teach-In. Since the devices include an IO-link interface, the digitized analog value is also displayed and the device can be easily programmed. The graphic operator interface offers more options than are available by adjusting the switching points with Teach-In. The distance measurement sensor can be optimally adapted to each task. This results in a wide variety of applications throughout all branches of automation technology.
The largest selection of sensors on the market is available for the proven housing design of the VDM28. In addition to the distance-measuring device, thru-beam sensors and retro-reflective sensors are also available. This housing design thus incorporates more optical technologies than any other.
