Absolute Rotary Encoder ACURO AR62

 Absolute Rotary Encoder ACURO AR62

The special features of the AR62 not only comprise its particularly rugged enclosure, but also generously dimensioned, rigid ball-bearings. Capable of withstanding even high axial and radial loads on its shaft axis, this encoder type easily achieves a mechanical life of 10 9 rotations at a permanent radial load of 300 N and simultaneously, an axial load of 300N.

The AR62/ 63 was designed to easily withstands highest accelerations, extreme climatic fluctuations and even underwater operation. In this way, our rugged absolute encoder is ideally suitable for applications in wind farms, marine or utility vehicle applications, as well as for use in presses or wood and stone processing machinery: applications where high resistance to harsh environments and maximum reliability are required at the same time. The AR62 is electrically compatible with standard industrial drives. Available interfaces are SSI, CANopen and Analog (0 ... 10 V or 4 ... 20 mA).

Single turn resolution is 12 bit, i.e. one revolution (360°) is resolved into 4096 measuring steps. The AR62/63 comes with a breakthrough multiturn technology, that provides a unique set of advantages: it operates contact less, self energetic, without battery and moving parts. Standard multi turn resolution is 16 Bit. With an installed depth of only 32 mm, this encoder is the most compact type in its class. Valuable space has been saved - to the benefit of the overall machinery design.
