These sensors work with a high-resolution CMOS line and DSP technology and determine distance using angular measurement. As a result, material, color and brightness related measurement differences are virtually eliminated. Integrated analogue output can be configured for voltage 0…10 V (10…0 V) or current 4…20 mA (20…4 mA).

Technology that moves in over three decades of wenglor sensoric. On this interactive journey through time, we researched deep into wenglor’s archives and have tracked the history of the company since the eighties – starting in an attic and growing into a global corporation.
In the food industry, it is important to accurately measure blocks of cheese on conveyors before cutting. This enables the amount of waste to be significantly reduced when the blocks are subsequently cut. To this end, two high-precision laser distance sensors are installed above and one on each side. The analog measurements can be used to calculate the volume of the cheese and thus determine the ideal frequency of the cutting knife. To avoid keeping the measuring sensors permanently in operation, a retro-reflex sensor is installed upstream as a trigger – this saves electricity and therefore costs.
