Technology

Multi-faceted and varied applications require laser distance sensors with versatile performance features. Besides different dimensions and ranges, beam formation plays a particularly important role. Thanks to continuous further development, Baumer is in a position to offer the new "multi-spot" measuring principle with three different beam shapes:
laser-point: measurement of small objects with a spot size of < 0.4 mm
laser-line: measurements on rough surfaces with a laser line of < 10 mm
multi-spot: measurements on extremely rough and inhomogeneous shiny surfaces with extra wide laser lines of < 62 mm

Diffuse sensors with background suppression – Triangulation

Triangulation

In the triangulation principle, the distance of an object is measured by means of the angle of incidence of the reflected light. The angle of incidence changes according to the distance, and thereby the position of the laser point on the receiver.

Retro-reflective sensor – Optical sensor principles

Time of flight

The time of flight (or also propagation time measurement) is a process for indirect distance measurement by measuring the amount of time that a signal requires to cover the measuring distance.

Light section

Light section

Based on the principle of triangulation. In conjunction with an emitted laser line and a matrix receiver, up to 600 items of distance information are determined and evaluated in the sensor.

Laser point for very small objects

Laser line for rough or colour structured surfaces – Measurement stability

Laser line for rough or colour structured surfaces

Multi-spot sensors for extremely demanding surfaces

Multi-spot sensors for extremely demanding surfaces

Stable measurements with over 600 measured values on inhomogeneous glossy or very rough surfaces by means of an extra wide laser line < 72 mm.

Ambient light immunity

Ambient light immunity

Powerful algorithms integrated in the sensor make laser distance sensors very insensitive to external light sources. This guarantees reliable, robust operation.

Programmable filter functions

Programmable filter functions

The noise of the output signal can be reduced by activating filtering, thus increasing the resolution.

Programmable measuring ranges

Programmable measuring ranges

The measuring range can be adjusted by the user within the maximum measuring range with the teach-in button, the teach-in line or through the display.
