Turck BIM-IKM Series Magnetic Field Sensors (AC Magnetic-field Immune) The BIM-IKM series are activated by magnetic fields making them ideally suited for detecting piston positions in pneumatic cylinders. As magnetic fields can permeate non-magnetized metals, these units can detect the position of a piston with a permanently mounted magnet through the aluminium wall of the cylinder. They are made even more versatile thanks to having a wide voltage range of 10 to 65 Vdc. A yellow LED indicates the switching state making it easier to monitor.

Weld-field immune permaprox sensors "freeze" the switching status when detecting a magnetic AC field (50 to 60 Hz). This prevents false switching operations during the welding process. The sensor will resume normal operation when the AC field disappears. Rectangular, height 34 mm
