• One sensor, two switching points: Reduces commissioning time and costs
  • Maximum flexibility thanks to a detection zone up to 50 mm
  • Suitable for precise pneumatic applications due to intuitive and precise definition of two switching points
  • Quick and easy installation and sensor replacement thanks to drop-in sensor mounting
  • Flexible sensor settings, monitoring, advanced diagnostics and visualization through IO-Link (depending on type)


On pneumatic cylinders, grippers, or carriages, the MZ2Q magnetic cylinder sensors from SICK are able to detect two end positions or intermediate positions with just one sensor. This is achieved by using two individually adjustable switching points in one sensor housing. This is much easier, quicker, and more cost-effective than conventional solutions, since only one slot is used. As a result, mounting and cabling overheads are halved and applications can be solved efficiently.

At a glance
  • Can be used in all standard cylinders, linear slides, and grippers using the T-slot and – with the help of adapters – in round rod, tie-rod, and profile cylinders, and cylinders with a dovetail groove
  • Drop-in mounting from above simplifies handling and assembly
  • Easy adjustment of two switching points via teach-in pushbutton
  • LEDs for indicating the two switching points
  • Detection range up to 50 mm stroke
