High-precision Positioning Switch

0.5μm in repetitive accuracy

0.5μm in repetitive accuracy

MT 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. 

IP67 protective structure Can be used in harsh environment

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.

0.0005mm repeatability has been proven by painstaking testing

The Pride of Japan Technology

[History of Development]
The origin of Precision Positioning Switches

"Precision Positioning" - Essential for Manufacturing.

An industrial-use mechanism which supports work at manufacturing sites.
One of the most essential elements when it comes to improving product quality and productivity is 'positioning'.

Precision positioning can be extremely difficult to achieve, even with the latest digital technologies...
