Patent ID: 7718951

Claim:
An encoder for a direct current motor having a motor shaft, the encoder comprising: a. an encoder housing, b. an encoder disk, c. a circuit board arranged perpendicular to the motor shaft and having an optic sensor, the circuit board encompassing the encoder disk in a U-shaped manner, and d. a connector plug aligned parallel to the motor shaft, wherein the circuit board is provided with i. accepting slots for connectors, ii. contact surfaces of the circuit board being partially arranged around the accepting slots, and iii. an electric contact between the connectors and the contact surfaces such that the encoder housing has an encoder housing ring and an encoder housing lid and the encoder housing ring is provided with a radial recess, which is arranged in the area of the connector plug, e. the optic sensor being arranged on the circuit board at the side of the connector plug and provided with an accepting slot for the encoder disk, which accepting slot is open in the direction of the motor shaft, on which the encoder disk is mounted, and f. the accepting slots are open towards the side of the direct current motor opposite the connector plug and towards the edge of the circuit board.
