Rotary Encoder Measures Speed without Ball Bearings
The MNI40 incremental rotary encoder from Pepperl+Fuchs is a magnetic, non-contact encoder with advanced diagnostics for a range of applications. It delivers resolution up to 3,600 pulses per revolution at speeds up to 30,000 revolutions/minute and operating temperatures from 40 degrees Celsius to 100 degrees Celsius.
The MNI40 is appropriate for a range of applications that include machine construction, wind power, mobile equipment, material handling lifts and conveying technology. Features include a two-color LED display, simple installation and setup, quality assurance through complete self-diagnosis and long service life, according to the company's press release.
"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."
A zero-contact connection between the encoder sensor and magnetic wheel enables the MNI40N encoder to measure speed without ball bearings. This eliminates bearing wear due to mechanical forces for extended operating life. The sensor includes sensing electronics, housed in IP67 rated enclosure and an elastomer-coated magnetic wheel, preventing damage from water and oil.
