MNI40 Magnetic Encoders from Pepperl+Fuchs


Pepperl+Fuchs introduces MNI40 incremental rotary encoders, a robust magnetic, non-contact encoder with intelligent diagnostics suitable for a wide range of applications. The MNI40 delivers resolution up to 3,600 pulses per revolution at speeds up to 30,000 rev/min and operating temperatures from -40°C…+100 °C. Robust, compact, and simple installation of the MNI40 make it an ideal choice for a wide range of applications including machine construction, wind power, mobile equipment, material handling lifts, and conveying technology. Primary features include clear indication via LED display (two-color), easy installation and setup, quality assurance through complete self-diagnosis, and long service life.

“The LED indications are particularly useful during installation and setup because they provide information on proper assembly,” says David Rubinski, product manager. “The integration of the LED also reduces installation time and test equipment requirements, and offers greater potential for reducing overall costs of machine and/or system construction.”

The MNI40 utilizes a zero-contact (magnetic) connection between the encoder sensor and magnetic wheel, enabling the MNI40N encoder to measure speed without ball bearings. This eliminates bearing wear due to mechanical forces and ensures long operating life. The sensor includes sensing electronics housed in a compact IP67 rated enclosure and an elastomer coated magnetic wheel, so contact with water and oil will not damage the encoder system.
