An encoder arrangement (2) adapted to be used with a rotary milking platform includes an encoder axle rotatable about an encoder axis (12), an encoder wheel (6) connected to the encoder axle, and a suspension arrangement (8) supporting the encoder and the encoder wheel (6). The encoder and the encoder wheel (6) are arranged on a movable portion (14) of the suspension arrangement (8). The movable portion (14) is biased towards the rotary milking platform. The movable portion (14) is pivotable about a pivot axis (16), and the pivot axis (16) extends perpendicularly to the encoder axis (12).
