Technology overview - distance sensors

ifm’s laser distance sensors leverage the advantages of pmd time-of-flight technology for accurate and long range distance measurement.

Light waves propagate from the laser light source. When the light bounces off the target, the phase pattern shifts and the shift is directly proportional to the distance.

This proprietary technology provides:

• Robust detection of small reflective targets
• Quick installation due to color and angle independence
• Measured distance information via IO-Link

ifm’s OGD, O1D, O5D and OID laser distance sensors all use this technology.
