The parallel, absolute angle information derived by the encoder is converted into serial information by an internal parallel-serial converter and then transmitted to a receiving electronic circuit in synchronism with a clock. Important advantages are : Low number of data lines and high reliability.

Please note: Standard magnetic actuators have an internal bore to accept shafts of 6 mm dia. Actuators with 4, 8 or 10 mm dia must be ordered separately, e.g. RBM-N08, for quantities up to 24 pieces. For larger quantities such actuators will become part of the standard item as per the order code, e.g. RBM 22 - 08 -512 R K1 E01.
