Mitutoyo PJ-PLUS Optical Comparators

The Mitutoyo PJ-Plus is a new series of profile projectors that utilize LED lighting and provides reliable measurements in manufacturing site environments. The PJ-Plus provides stable dimension and angle measurements in harsher environments conventional models can’t handle, such as manufacturing and processing lines.

Thanks to the LED light source, the PJ-Plus series now uses close to 85% less power consumption when compared to other Optical Comparators. Not only does the LED use less power than a standard halogen bulb, it also does not generate heat like the halogen bulb does, thereby eliminating the need for a cooling fan. Not only does this lower the overall power consumption, but it has also drastically decreased the entry of oil mist and dust via the cooling fan into the instrument body.

This also drastically reduces adhesion of oil and dust to the internal mirror, lens, and light source. As compared with the conventional model, the LED light source type improves the rate of decline in illuminance by about 50 %. It maintains high optical performance by preventing the entry of mist into the main unit even in the harsh environment of a processing line.

Stepless Illumination Adjustment The conventional 2-step illumination adjustment has been changed to stepless control so the level of illumination can be precisely set to suit the surface texture and color of the workpiece.
High Visibility Digital Display Since the digital counter (XY axes and angle) built into all models as standard uses a high-intensity LED and a large character display, it secures high visibility unaffected by the environment. In addition to zero-setting and direction change, the data output of each counter value adopts the highly versatile RS-232C. Resolution: 0.0001 in/ 0.001 mm
