The MNI40N comes with intelligent diagnostics that deliver resolution up to 3,600 pulses/revolution at speeds up to 30,000 rev/min and operating temperatures from -40°C...+100 °C. F. 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.
