Laser Distance Photoelectric Sensors

The OID is an IO-Link distance sensor with time-of-flight measurement based on PMD technology (PMD = Photonic Mixer Device). It combines the advantages of long ranges, reliable background suppression, visible red light and high excess gain in one compact, robust M30 stainless steel housing.
The sensor is perfectly fitted for use in extremely harsh industrial environments thanks to its high protection rating.

Thanks to IO-Link, the switch point can conveniently be set from a controller or PC. Unintentional maladjustment directly on the sensor is thus excluded and increases the protection against tampering.

The accurate background suppression ensures that even shiny, matt, dark or light objects are safely detected. The unit allows any angle of incidence and thus any mounting position, which facilitates installation and saves costs.

Versions with laser class 1 meet the requirements of applications in the automotive industry.

Description

Technology

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
