Displacement measurement sensors OD7000 - SICK

The OD7000 from SICK is a chromatic confocal distance sensor. It measures distances to objects very precisely and cost effectively – regardless of their surfaces and materials. With resolution down to 25 nm, the high-performance sensor reliably detects whether surfaces are smooth, or whether objects are positioned precisely or have the desired material thickness.

Since the sensor head and control unit are separate from one another, the compact OD7000 is easy to install even in tight measurement locations. Thanks to the intuitive user interface, the device can be quickly configured. Its Ethernet and RS-422 interfaces make system integration easy. The OD7000 from SICK is available in six measuring ranges and two controller types, one with triggering via an encoder signal, and one without.
