The IFM MR0901 T-slot cylinder sensor with reed contact is designed for magnetic piston-position detection in pneumatic cylinders. The MRI2021-AKOA/R/AS configuration provides a compact sensing solution with an integrated M8 connector and combined AC/DC output technology. IFM highlights its self-locking mounting, easy top-down installation, two-wire technology and high switching frequency. The model is listed by IFM as discontinued from March 31, 2026, with MR0101 identified as its replacement.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The MR0901 is a T-slot cylinder sensor designed for conventional pneumatic-position monitoring. It uses reed-contact technology to detect magnetic piston movement and provide a switching signal. Its compact cylinder-mounted format makes it suitable for automated machinery. The integrated connector arrangement can simplify connection and replacement during machine maintenance.
IFM specifies a combined AC/DC output and two-wire technology for the MR0901. This makes the sensor suitable for conventional control applications. The reed contact responds to the magnetic field of the piston and provides a switching indication when the piston reaches the sensing zone.
The MR0901 uses a self-locking fastening concept and supports easy drop-from-the-top installation into the cylinder slot. IFM also identifies an integrated M8 connector and high switching frequency. These features support convenient installation and maintenance in suitable pneumatic systems.
The MR0901 is suitable for pneumatic cylinder monitoring in assembly, packaging and handling equipment. It can provide position feedback for machine sequencing and actuator control. As IFM has listed this model as discontinued, new installations should consider the manufacturer's stated replacement information when selecting a product.
