Metrol Air micro sensor [DPA-SR1/LR1 series]

The air micro sensor DPA series is a pneumatic high-precision sensor that can "confirm close contact" between a workpiece and a jig. In an environment where air can be used, it is possible to simultaneously check not only "presence/absence confirmation" but also "adhesion confirmation (floating)" with a repeatability of ±0.5μm. Prevents machining defects and equipment downtime due to poor seating. It has been introduced in machining processes where automation is progressing, such as clamping precision workpieces, semiconductor manufacturing processes, and transfer lines. ±0.5μm Repeatability Accurately detects improper seating of jigs and workpieces due to chip bite. IP67 coolant protection structure enables installation of sensors inside machine tools. Shortened air piping to air nozzles improves response speed. Faster and more productive Master settings are easy. With self-diagnosis function. Prevents the occurrence of processing defects at the stage of the manufacturing process
Optimal for confirming seating when machining engine parts, confirming seating of die-casts with rough surfaces Optimal for confirming shank contact, and confirming close contact when machining tire molds For finding the origin of CNC lathe processing and confirming close contact with the mold during hydraulic press working optimum
