CS-Touch Sensor
The best-seller switch

  • 5 micron in repetitive accuracy without an amplifier
  • A wide variety of shapes
  • High cost performancey

M5~ Compact design

Compact designMutual interference doesn’t occur when several switches are used closely with the interval of 5mm.

Eliminate costly intermediate actuators and design the machine compact.

Existence detection

Normally, those micro switches and non-contact type sensors (such as proximity sensors) are operated by the intermediate actuators or equivalent transmitting parts. And that results in costly designed machanism.

METROL Ultra precision Switches

METROL switches can touch the detected objects directly by choosing the appropriate contacting part.

High cost performance

Only ON/OFF output, but 0.005mm for repetitive accuracy is obtained by extremely lower price than that of digital micrometers and displacement sensors.
