The AVENTICS Series ST6-SM are position sensors, which ensure a continuous detection of the piston movements in measuring ranges up to 50 mm. IO-Link allows setting of 8 switching zero point The compact sensors of 32,5mm are easy to mount in the 6mm t-slot. The actuator diagnosis function of the sensor uses performance data such as piston velocity, piston travel or number of piston strokes to make the processes in pneumatic drives visible.
