The U18T ul­tra­so­nic sen­sors in the wi­de­ly used M18 for­mat com­bi­ne ro­bust con­struc­tion with in­tel­li­gent tech­no­lo­gy. The M18 th­read de­sign of­fers a clear ad­van­ta­ge: It en­ables fast, tool-​free and ef­fi­ci­ent in­stal­la­ti­on. Due to their high sta­bi­li­ty and re­lia­bi­li­ty, U18T sen­sors are sui­ta­ble for a wide range of ap­pli­ca­ti­ons with a de­tec­tion range of up to 2,400 mm. They are ideal for de­tec­ting shiny, trans­pa­rent and dark ob­jects and can even re­lia­b­ly de­tect mir­ro­red sur­faces. With their in­te­gra­ted IO-​Link in­ter­face, they offer ad­di­tio­nal fle­xi­bi­li­ty and easy in­te­gra­ti­on into va­rious sys­tems.

Com­mon Cy­lin­der De­signs with M18 Th­read for Easy In­stal­la­ti­on


This video shows a prac­ti­cal ex­ample de­mons­tra­ting how quick­ly and ea­si­ly the U18T ul­tra­so­nic sen­sors can be in­stal­led. In­stal­la­ti­on is ex­tre­me­ly ef­fi­ci­ent and easy thanks to the wi­de­ly used th­rea­ded de­sign.

Pos­si­ble Uses for U18T Ul­tra­so­nic Sen­sors

Ob­ject De­tec­tion

In the food in­dus­try, baked goods are trans­por­ted in boxes through the va­rious process steps. Be­fo­re clea­ning the boxes, it has to be en­su­red that there is no pro­duct left in the boxes. For this pur­po­se, two ul­tra­so­nic di­s­tance sen­sors are in­stal­led next to each other above the con­veyor belt, which emit ul­tra­so­nic waves and thus check the con­tents of the boxes.

Pre­sence Check

In the fur­ni­tu­re in­dus­try, woo­den pa­nels with dif­fe­rent co­lors, sha­pes, de­grees of gloss and sur­faces are con­veyed on rol­ler con­veyor belts to the next process step. In order to mo­ni­tor the trans­port fully au­to­ma­ti­cal­ly, the pre­sence of the pa­nels must be re­cor­ded at all times.
