No control motor, so strong durability against coolant. Air-driven tool breakage detection sensor.
The "DFM3 Series" is a tool breakage detection sensor that can be installed on machine tools such as automatic and dedicated machines, detecting tool damage by making contact with drills, taps, reamers, etc. It exhibits outstanding durability in harsh environments and has a long lifespan even in conditions where chips and cutting oil are present. Additionally, it employs a new method that does not use a control motor, eliminating failures caused by coolant. 【Features】 ■ Protection structure IP67 ■ Detects tool damage by making contact with drills, taps, reamers, etc. ■ Outstanding durability ■ Long lifespan even in harsh environments with chips and cutting oil ■ No failures caused by coolant *For more details, please refer to the PDF document or feel free to contact us.
