METROL specialize in manufacturing Tool Setters & Precision Positioning Switches

Ultra precision position Swhitches  Metrol

High-precision Positioning Switch [MT]

0.5 micron in repetitive accuracy!

IP67, resistant to harsh environments with coolant oil or metal cuttings.

The precision positioning has been achieved under harsh working conditions such as CNC machine tools or automobile manufacturing lines.

Reasons to choose High-precision Positioning Switch

0.5 micron in repetitive accuracy!

MT-Touch switches were co-invented with TOYOTA as a precision switch which can stably output the ultra-high-accuracy positioning signals under harsh working conditions such as automobile manufacturing lines where coolant and cutting chips splatter.


IP 67 protective structure! Can be used in harsh environment!

The special coating gum has been adopted for waterproof and is applicable to water as well as a wide range of coolant (especially for alkaline).

The total 500,000 of this type switch has been used in machine tools where coolant and cutting chips splatter for an use of starting point.

Disadvantages of contact type

  • Untouchable objects such as liquid or soft objects cannot be detected.
  • The takt time might be longer because a switch takes time to touch a workpiece.
  • Measuring range gets narrower compared to non-contact type due to detection by touching workpieces.
