METROL specialize in manufacturing Tool Setters & Precision Positioning Switches

Ultra precision position Swhitches  Metrol

Ultra-small Precision Positioning Switch [PT]

The world’s smallest!
M5 x 17 mm

The world’s smallest Precision positioning switches.
These switches make it possible to downsize machines by installing directly to semi-conductor manufacturing / automotive manufacturing / metal mold / medical equipment.

Reasons to choose Ultra-small Precision Positioning Switch

Downsize machines with the world’s smallest switches!

The world’s smallest M5 x 17 mm Precision positioning switches.

Used for origin detection in various industrial machines and medical machines such as CNC machine tools, semiconductor production equipments, microscopes for neurosurgery and disc brakes.

1μm repeatability, 3 million contact life time!

The precision positioning switch using no amp does not cause signal point drift due to external environment or self-generation and can output stable high precision signals.

This ultra small switches endure 3 million times operation mechanically and electrically.

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.
