Pneumatic cylinder position sensors

The MZT8, MZ2Q and MPS series magnetic cylinder sensors are designed to meet the needs of numerous automation requirements that use pneumatic cylinders.

The MZT8 is used to detect one switching point and at 24 mm uses little space. This has been made possible by an ASIC chip technology that also provides scattering of the switching point of ±5%. The sensor has high resistance to cutting fluids and coolants and the housing is completely watertight.

The MZ2Q magnetic cylinder sensor provides two freely adjustable switching points in a single device, for greater functional reliability with rapid piston movements, redundant end-position detection in miniature cylinders, or the precise detection of different gripper positions. The advantages of the two-in-one sensor concept are: occupancy of a single slot, less mounting effort and reduced wiring on the pneumatic cylinder. The MZ2Q series also includes an IO Link interface so that it is easily integrated into a machine’s network environment.

The MPS magnetic position sensor provides analog piston position detection on pneumatic cylinders, and is suitable for travel speeds of up to 3 m/s and covers measurement ranges of 32, 64, 96 or 128 mm. The two circuit boards within the IP67-protected sensor housing accommodate Hall sensors for non-contact position detection, the controller and the teach-in element. The zero and end points can be taught-in via the Teach button regardless of the actual piston position. The intermediate piston positions are transmitted as analog signals, available as a 4-20 mA current output and as a 0-10 V voltage signal.
