ifm’s E21248 Cooling box
Small in size, ifm distance sensors with time-of-flight measurement based on PMD technology (PMD = Photonic Mixer Decide) are distinguished by a very long range, reliable background suppression, a visible red laser light spot and a high excess gain.
The sensors are resistant to extraneous light and can be used in workshops where daylight hits the sensor or object from above. Reflective objects such as metal surfaces are reliably detected; reflective strips on high-vis vests reliably supressed.
Distances can also be measured reliably when the light beam does not hit the object surface vertically. This allows flexible mounting, facilitates installation and saves costs. The accurate background suppression ensures that even shiny, matte, dark or light objects are safely detected.
The distance sensors are designed for positioning, speed control and level monitoring tasks. For example, they can be used to protect autonomous industrial transport systems or cranes against collision or position industrial trucks in high rack storage areas.
Using ifm’s E21248 Cooling box can also assist distance sensor use in harsh environments. In the picture example above, when monitoring the material at the intlet side of a furnace, you need to be able to detect the position of the billets. The furnace door is extending over the whole width of the walking beam furnace and can only be closed when the billet is completely inside the furnace.
Closing the furnace door at an early stage saves energy, and a laser distance measurement sensor is used to detect the position of the billet on the roller conveyor in front of the walking beam furnace.
For ambient temperatures of up to 180 °C powerful electronics should be cooled to protect against overheating. Using the cooling box, the distance sensor O1D can also prove its performance in hot applications and ensures a reliable mechanical protection in very harsh environmental conditions.
