The programmable multiturn sensor ETA25PM can be parameterized by the customer on site to the desired angular measuring range and sense of rotation up to 10,000 times. Only one device for different angles of rotation, sense of rotations direct parametrizable on site. These advantages enable the user the possibilities to set up the ETA25PM multiturn encoder to the requirements of the application on site. Only one angle encoder device for different requirements is needed, which can be parameterized almost as often as required. The ETA25PM measures angles from 0…10° up to 0…72000° (absolute). The ETA25PM is available until protection class IP66 and has a long durability of more than 100 million shaft revolutions. The compact sensor in the 25 mm housing with Ø6 mm or Ø6.35 mm shaft diameter is e.g. optimally suited for use in drive units as position feedback. A variant of the ETA25PM with integrated buttons for angle programming and sense of rotation is available on request.
