Features

1 micron in retitivepe accuracy without an amplifier

Compact as it is, the switch can achieve 1μm repeatability.

Repeatability is measured with the Agilent laser measurement system.

3 million contact life time.

Endurance tests were repeated over 10 million operations to ensure an durability of 3 million operations.
Despite being a mechanical type, the switch has an assured durability of 3 million operations.

Used for position detection in various industrial machines.

Used for Origin Detection in various industrial machines and medical machines such as CNC machine tools, semiconductor production equipment, microscopes for neurosurgery and disc brakes.

Applications of Positioning Switches

  • Positioning of the workpiece

    Control of the production line with a hight precision.

  • Zero seek for robots

    Correction of the thermal displacement of the Z-axis with a hight precision.

  • Positioning of the tabel

    Control of the X- and Y- axes with a hight precision.

  • Positioning within machine tools

    Use in adverse environments caused by scattering chips and cutting-oil.

  • Positioning of the end face of equipment

    Control of the starting point of equipment.

  • Tool preset

    Correction of the position of worn edged tools with a hight precision.

ZEN of Design and Manufacturing

Most of the people may imagine the Electrical Switch in the house when they hear the term SWITCH.
Yet, SWITCHES are one of the Machine components that support Monozukuri of various products.

There are thousands of switches that are playing important role in precise “positioning” of machines and working robots in manufacturing plants and works worldwide, as “positioning” of any machine or workpiece determines quality of products…
