About MP3

MP3 machine tool probe

The MP3 is ideal for job setting and component inspection applications on larger machining centres. Its size gives exceptional robustness and generous stylus overtravel, while maintaining high precision.

The MP3 probe signals can be transmitted to the machine control either by an inductive, optical or radio transmission system. Note that the optical and radio transmission systems for MP3 are now both obsolete.

MP3 system options

MP3 with IMM/IMPMP3 with OMPMP3 with RMP
Inductive transmission system for battery- free operation.

Optical transmission method - obsolete.

Consider OMP60 as an alternative.

Radio transmission method for use in larger machining centres - obsolete.

Consider RMP60 as an alternative.
