High-accuracy MT-Touch Sensor

High-accuracy MT-Touch Sensor
0.5 micron in repetitive accuracy without an amplifier

  • Co-invented with TOYOTA in 1976
  • Protective structure IP67
  • High cost performance

Co-invented with TOYOTA in 1976

CNC工作機械に、30万台以上の採用実績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)
Conventional way

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.
Improved way

Protective structure IP67

Protective structure IP67Inner 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.
