The non-contact optical VLM60 is a modern speed and length measuring device in a robust aluminum IP65 housing. An automatically controlled white light LED illuminates the surface of the measuring object. The reflected light is projected onto the optical track image sensor by the integrated precision optics. The movement of the measurement object is recorded in this way by means of a correlation method. The speed is measured bidirectionally in both the x and y directions. The VLM60 can be used as a direct replacement for measuring wheels. The built-in TTL pulse output has two phases A and B for both directions of movement. Optionally, the contactless sensor can be expanded to include an Ethernet-based fieldbus interface. Thanks to the flexible installation position, the small dimensions and the short measuring distance of 100 mm, the VLM60 can be easily integrated into a wide variety of systems.

2D Motion Detection
Using its special 2D measurement method based on the correlation principle, the VLM60 simultaneously detects object motion in both the longitudinal and transverse directions. From this, it also simultaneously calculates the resulting velocity and length.

Robust and versatile
Due to its robust construction, the VLM60 is designed for use in harsh industrial environments. The degree of protection IP65 enables measurements even under adverse measuring conditions. This enables the device to record speeds and lengths in a large number of production processes.

Low service and maintenance costs
Due to the non-contact measuring principle, the VLM60 not only works more precisely than contact rolling systems, but also without friction-related wear. This minimizes the service effort and also prevents damage to or influence on the surface to be measured.

Flexible and integrable
The user can easily and flexibly adapt the output signals to his application thanks to the parameterization. Among other things, acquisition and output times, sliding averaging or the scaling of the pulse output can be parameterized. The VLM60 can also be easily integrated into existing processes, controls or process data acquisition through its optional fieldbus interface. The Windows-PC based "VLMTool" software is available for download free of charge.
