Sensor ini adalah sensor putaran dari jenis optical incremental rotary encoder. Optical artinya prinsip kerjanya dengan menggunakan piringan transparan yang diberi garis hitam dengan sumber cahaya LED dan sensor cahaya photodiode. Gerakan pada poros akan mengakibatkan gerakan garis hitam, sehingga akan timbul pulsa pada sensor photodiode. Incremental artinya sensor ini hanya mengukur gerakan relatif, bukan mengukur posisi absolut poros.
