Product information
The VDM28 distance measurement device
employs Pulse Ranging Technology (PRT).
It has a repeat accuracy of 5 mm with an
operating range of 0.2 ... 15 m and an
absolute accuracy of 25 mm.
The compact housing of the Series 28
photoelectric sensors, with dimensions of
88 mm (height), 26 mm (width) and 54 mm
(depth), make it the smallest device available
in its class.
