A replacement of the optical fiber sensors reduced sensor set-up time significantly

A replacement of the optical fiber sensors reduced sensor set-up time significantly
  • Accuracy improvement
  • Ball Plunger Switch BP
  • Transportation equipment


    • A bearing manufacturer that produces ball transfers.

    A representative of the design department of conveyor systems inquired us about the positioing of conveyed objects.

    The "Optical fiber sensors" have been used for positioning objects on the conveyor, but it took a lot of time for sensor setting.


Client's Issues

A replacement of the optical fiber sensors reduced sensor set-up time significantly

Since signal point of the "Optical fiber sensors" varies according to materials and reflection rate of the conveyed objects, frequent sensor replacement which takes long set-up time is necessary for small lot multi-product production lines.

He contacted Metrol through the website, looking for sensors capable of detecting various kind of objects.

  • Signal point varies according to the materials of the conveyed objects.
  • Sensor setup is necessary each time the production line is changed.


Metrol's suggestions

A replacement of the optical fiber sensors reduced sensor set-up time significantly

"Switches are not durable and are easily broken. They cannot be used for positioning in production lines"
Many of on-site engineers have these doubts.

Metrol's "High-precision Positioning Switches" are contact type On/Off switches, but can sustain 10 million operations as well as demonstrate 5µm in repetitive accuracy.

Positioning switch included in a ball transfer indirectly touches objects on conveyors.

In this way, sensor setup is no longer necessary when the production line is changed, reducing set-up time significantly,

  • Realize positioning by contact detection without being affected by the materials of the conveyed objects.
  • Reduce set-up time significantly because no sensor setup is necessary.
