OMI-2 / OMI-2C Interface

OMI-2

About OMI-2

OMP60-OMI-2The OMI-2 optical machine interface is designed to reside in the machine's working envelope. Its purpose is to send and receive probe signals. The OMI-2, like the OMI, has the added benefit of supplying totem pole (transistor) output, thus eliminating the need for a separate MI 12 interface.

OMI-2 differs from the OMI in that it offers the new modulated transmission method, providing increased resistance to optical interference.  

About OMI-2C

OMI-2CThe OMI-2C is an alternative to the OMI-2, providing the same capability in a package that can be integrated into the machine's spindle housing.

The OMI-2C is suitable for use with Heidenhain and Siemens controllers.

 

Compatible probes

Renishaw's new generation of optical probes offers the new modulated transmission method, allowing them to be used with OMI-2, OMI-2C and OMI-2T combined interface/receiver units. These probes are also 'backward compatible'; they can be configured to communicate by the earlier legacy transmission method, so you can upgrade to a new generation probe module without having to upgrade your transmission units.

OMP40-2 - offers legacy and now modulated optical transmission methods

OMP60 - offers both legacy and modulated optical transmission methods

OMP400 - offers both legacy and modulated optical transmission methods
