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.
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
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
Applications
Detection of the starting point in the blade edge of tool machines
Resistant to harsh environments with coolant oil or metal cuttings.
Dimension measurement of a workpiece on the surface grinder
Measurement of workpiece end surfaces with 0.5μm precision.
Detection of wear of compact carving machine tools

[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...
