No more machining defects caused by chip entrapment! We can reliably detect workpiece lift-up within ±0.5µm.

±0.5μm repeatability! Machining defects caused by workpiece seating failures on CNC machines are now eliminated.

The traditional pneumatic "gap sensor," which could only detect presence or absence, has been revolutionized to achieve precise seating confirmation of "jigs" and "workpieces." This sensor reliably detects workpiece lift due to chip entrapment, preventing machining defects at the manufacturing process stage.

◆ Three Key Features of the Single-Point Setting Air Micro Sensor
① ±0.5µm Repeatability
Compared to traditional "gap sensors" and "air sensors," which typically have a repeatability of around 20µm, this sensor has minimal signal point variation, ensuring reliable detection of workpiece seating failures due to chip entrapment.

② IP67 Coolant Protection Structure
The sensor can be installed inside the machine tool. Shortening the air piping to the air nozzle increases response speed and improves productivity.

③ Easy Master Setting
Setting the signal point is as simple as placing a master within the allowable tolerance of the jig and holding the master set button for one second.

◆ Improvement Examples with the Single-Point Setting Air Micro Sensor
