In one embodiment, an encoder system comprising an encoder assembly and an encoder alignment structure is disclosed. The encoder assembly may include at least a detector, a hub, a housing, an index sensor of the detector, and a coding member having an index mark. The encoder alignment structure may have a projecting structure. The detector may be coupled with the housing, and the projecting structure may slideably engage the hub so as to align the index mark of the coding member with the index sensor of the detector in a first alignment arrangement. In another embodiment, an encoder assembly configured for receiving an alignment structure having a projecting structure is disclosed.

System and assembly structure for aligning an encoder

An encoder system comprising an encoder assembly and an encoder alignment structure is disclosed. The encoder assembly may include at least a coding member, a hub, and a housing. The encoder alignment structure may comprise a major surface, a plurality of catches, and a recessed region. The major surface may be coupled with the housing to substantially enclose the hub and the coding member. The plurality of catches may be disposed around the periphery of the major surface and may be configured to secure the encoder alignment structure to the housing. The recessed region of the major surface may be converging from the periphery of the major surface between two of the plurality of catches towards the hub so as to provide access for a user to adjust the hub around the axis of rotation.

Encoder alignment structure

A sensor head for sensing light modulated by a moveable member, such as a code wheel or code strip, in an optical encoder. The sensor head has at least one monitor optical sensor and a primary optical sensor positioned to receive light modulated by a modulation track on the moveable member. The monitor optical sensor provides a monitor signal that is compared in a signal comparator to the output from the primary optical sensor to detect light at the primary sensor.
