MNI20 and MNI40 bearing-free encoders – Magnetic with ring or wheel up to 30,000 rpm

In bearing-free encoders the connection between sensor and magnetic wheel is non-contact: no ball bearings are needed, which guarantees a long service life even at high speeds up to 30,000 rpm and allows much larger hollow shaft diameters than conventional encoders. They work reliably even with large shaft play or bearing gap and are also suitable for heavy-duty applications.

• MNI20: Ø 15 or 25 mm magnetic ring, allowing the cable to be routed through the hollow shaft
• MNI40: magnetic wheel with 50, 64 or 72 poles and 6 to 30 mm bore, with zero pulse

Key features

• Up to 10,000 pulses, 10…30 V push-pull or 5 V RS-422 output
• Assistance function and LED indicator for simplified installation and testing
• Full self-diagnosis, including the magnetic wheel
• Resistant to dirt, thermal and mechanical shocks and high-pressure cleaners

These products are ordered via a type code: the codes in the table are partial type codes taken from the Pepperl+Fuchs guide, where “…” marks the options still to be defined (flange, connection, resolution and so on). Tell us the configuration you need in the quote request and we will confirm the full part number and its datasheet.

Use the filters in Variants and codes to find the exact part number: every code links to the official Pepperl+Fuchs datasheet and to a quote request. For versions not listed, accessories or availability, contact us.
