Turck BI2CRS1159AP4X2H1141S34 Cylinder Position Sensor

The Turck BI2-CRS1159-AP4X2-H1141/S34 cylinder position sensor delivers non-contact piston position feedback for pneumatic cylinders in industrial automation. It detects piston position through magnetic field sensing (magneto-resistive) with the target being a magnet-equipped cylinder piston, and is commonly mounted in cylinder slots (T-slot or C-slot with adapter) for end-of-stroke or intermediate-position detection. The unit operates on 10–30 V DC and provides a PNP switching output (configuration dependent; normally open or programmable depending on variant). Its polypropylene overmolded housing offers IP67/IP68 protection (variant dependent), and it uses an M12 connector (H1141 style) for robust field wiring, with an operating temperature range of -25°C to +70°C. Applications include pneumatic cylinder position feedback for OEM machinery, automated assembly lines, packaging equipment, and industrial robotics, where precise piston position feedback drives machine sequencing and control in continuous-duty automation.
