MIK36 & MSK36: the non-contact and wear-free rotary encoder
Encodeur, Codeurs, Codeur absolu
Lika Electronic introduces a new compact and bearingless rotary encoder available in both incremental and absolute versions, designed for installation in small-diameter shafts under aggressive environmental conditions. Ideally suited even for position and velocity measurements at highest speeds up to 40,000 RPM.
MIK36 & MSK36 come to expand the family of the incremental and absolute bearingless encoders from Lika Electronic and provide designers with a rugged measuring system free of moving parts, contact, friction and wear.
The use of a magnet and a completely separate sensing circuit increases the toughness and reliability characteristics of the encoder. The magnet has a 6- (0,24”), 8- (0.31”) or 10-mm (0.39”) bore for installation in the output shaft of an electric motor, an actuator or a drive. The two elements are independent and work without any contact and mechanical connection to each other. This fully prevents the shocks, vibrations, mechanical stresses and eddy currents to be transmitted from the rotating shaft to the sensing element and, along with the absence of wearable parts such as bearings, means greater service life, efficiency and signal transmission safety as well as minimum downtimes and lower maintenance costs. In addition the robust and compact enclosure for the sealed circuitry (36-mm/1.4” diameter, 31.6-mm/1.2” depth) ensures IP68 protection rate. These properties make MIK36-MSK36 exceptionally well suited for the harshest industrial environments and any very severe applications including mining and oil field equipment, steel mills, marble, stone and glass working machinery. By virtue of the advanced magnetic sensing electronics, they can be further installed for accurate position and velocity detection in rotary applications up to 40,000 RPM such as in motors for spindles of lathes and mills and in a variety of machine tools and CNC machining centres.
This bearingless encoder is offered in both incremental and absolute versions.
MIK36 incremental encoder provides a resolution up to 2048 PPR and generates digital signals (AB0, /AB0) through NPN, Push-Pull and Line Driver output circuits. The max. counting frequency is 300 kHz.
MSK36 delivers the absolute position information with 13-bit resolution via SSI interface in either Binary or Gray code. It implements Zero setting and Complementary functions.
Both axial and radial cable options are available.
Reverse polarity and short circuity protections further increase the safety level.
