Positioning with sensors

In order to be able to pick up a workpiece or component from a belt with a targeted robot gripper one has to know the exact position in advance.

Background suppression

Our photoelectric proximity sensors with background suppression in the FT 10-series and FT 25-series are ideally suited for such tasks. If, in a pick & place application, the X-/Y-position and orientation are also required, or if complex assemblies must be inspected for correct and complete assembly, we recommend our vision sensors in the VISOR® series, which can detect several features in a single pass. Read more about vision sensors and cameras.

Precise circuit board front-edge detection

The front edges of circuit boards are registered with the FT 10-RLH sub-miniature sensor with background suppression. Read more about F 10-series sensors.

  • Flexible mounting thanks to adjustable background suppression
  • Reliable detection even with reflective metallic parts in the background
  • Very low space requirement(dimensions only 21 x 14 x 8 mm 3)
  • Precise switching behaviour due to small laser light spot (Laser Class 1)

Object front-edge detection

One FT 25-RHD photoelectric proximity sensor with background suppression detects the front edges of individualised chocolate bars. Read more about F 25-series sensors. 

  • No impairment by highly reflective or moving backgrounds and transport belts
  • High scanning distance with all common materials and surfaces
  • Adjustable, precise background suppression (distance measurement principle)
  • Simple scanning distance adjustment via teach-in
  • Very easily visible light spot for simple alignment
  • Wide range of different types and designs
  • Also available as a laser version for highly precise detection tasks

The FT 25-series proximity switch is available with a protection degree of IP69K

Monitoring IC pins

The fine light beam of the FT 25-RLH laser sensor from SensoPart permits precise detection of even small objects.

  • Reliable even with highly reflective metal parts
  • High scanning rate possible with high switching frequency
  • Independent of object colour and surface
  • Backgrounds located very close to the object are reliably suppressed
