Laser Distance Photoelectric Sensors

The OID is a 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 housing.

Switch point setting of the unit is easy and intuitive via a scaled setting ring (easy-turn). A scale shows the distance set. The switch point can thus be set before installation.

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.

Reliable background suppression and color-independent detection
Easy parameter setting via adjustment dial
Reliable detection of glossy surfaces
Oblique angle to the object possible
User-friendly communication via IO-Link

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
