High-accuracy MT-Touch Sensor
|
Co-invented with TOYOTA in 1976
MT-Touch Sensor was developed as high-precision switches working in harsh environments such as car manufacturing lines where coolant and metal cuttings exist.
In machine tool industry, accumulating total 450,000 of this type switch were already used as Tool Setters by machine tool builders.
Nowadays MT-Touch Sensors is used by many engineers that realize the cost-effectiveness it brings in various machines and automated systems.
Output highly reliable position signals. No accidental error signal.
0.0005mm repeatability without an amplifer. No movement differential. Detect microns difference in dimension.

Contact type switches are not affected by materials and shapes of detected objects.
Non-contact sensors
Detecting distance varies depending on the condition of objects. (Material, shape, and dimension)
METROL Ultra precision Switches
No influence from the external conditions or the material/ shape/ dimension
of the object.
Certain values are given for the pretravel according to each product.
- PretravelMT-Touch Sensor
Pretravel 0mm *
* Except certain models - CS-Touch Sensor
Pretravel 0.2mm*
* Except certain models
Protective structure IP67
Inner switching part is tightly sealed so that the switches can be used in a harsh machining environment
(water, oil and coolant).
High cost performance
Only ON/OFF output, but 0.0005mm for repetitive accuracy is obtained by extremely lower price than that of digital micrometers and displacement sensors.
Applications
-
Angle discrimination
-
Compensation for drill position
-
Outer dimension mesurement
