Ball Plunger Switch

Ball Plunger Switch Series

World's smallest micro-ball plunger switch sensors at φ4

Touch switch sensor built into a conventional ball plunger. Indexing by ball contact and confirmation signal output are performed simultaneously. Reducing the number of parts allows for miniaturization of the machine.
Can be applied for indexing and positioning by notches in indexing rotators/sliding parts.

  • Made in Japan
  • High Durability
  • Long-selling
  • Cust Reduction
  • High Precision
  • Ultra-compact

Why Choose Us

The two-in-one touch switch sensor supports downsizing of machines.

The two-in-one touch switch sensor supports downsizing of machines.

The combination of an ultra-compact ball plunger of φ4 to 5 with a touch switch reduce number of parts and downsize the design.
Allows installation in tight and difficult spaces.

Capable of detecting rotating objects by ball contact

Capable of detecting rotating objects by ball contact

With a built-in spring, the ball at the tip moves in and out depending on the load and simultaneously outputs a signal.
Ball contacts are ideal for detecting sliding mechanisms and checking indexing tables for positioning of sliding works.
When the load is released, the ball returns to its original position by spring force.

Machine life of 1 million cycles

Machine life of 1 million cycles

Even with its small size, the long-lasting design has a machine life of 1,000,000 cycles.
