MMK36 is the only multiturn absolute encoder with bearingless shaft in the market. Still it is capable of reliably and safely withstanding the most aggressive environmental conditions and ideally suited even for position measurements at speeds up to 4,000 RPM. -Multiturn encoder; -Bearingless and very small footprint design; -Non-contact, wear-free operation; -IP67 / IP68 protection with sealed electronics; -Speed up to 4,000 RPM; -Resolution up to 8192 cpr x 65536 rev.; -SSI interface. MMK36 from Lika Electronic is the only multiturn absolute encoder with bearingless shaft in the market and provides designers with a rugged and space-saving measuring system free of moving parts, contact, friction and wear. The use of a stainless steel rotor with integrated magnet and a completely separate sensing circuit increases the toughness and reliability of the encoder. The magnet assembly 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 magnet and the sensing element 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 electronics and, along with the absence of wearable parts such as bearings, means greater service life, efficiency and signal transmission safety. Thus there is no cause for concern about bearing wear, shaft loading or mechanical overheating. In addition the robust and compact enclosure ensures up to IP68 protection rate with sealed circuitry. These properties make MMK36 exceptionally well suited for the harshest industrial environments and any very severe applications including mining and oil field equipment, steel mills, utility vehicles and construction equipment. By virtue of the advanced magnetic sensing electronics, they can be further installed for accurate position detection in rotary applications up to 4,000 RPM. MMK36 delivers the absolute position information with an overall resolution up to 29 bits (8,192 cpr x 65,536 revolutions) via SSI interface in either Binary or Gray code. It implements Zero setting and Counting direction functions. Both axial and radial cable options are available. Reverse polarity and short circuity protections further increase the safety level.
