Linear encoder and method of adjusting a gap between a sensor unit and a scale of the linear encoder

摘要

A linear encoder includes a housing, a scale disposed within the housing and a sensor unit disposed within the housing facing the scale with a gap between the sensor unit and the scale. The sensor unit is configured to scan the scale and obtain position information. At least one adjustment hole for a gap adjustment is disposed in at least one of the housing and an end cover of the housing at a position corresponding to a position of the gap.

1. A linear encoder, comprising:
a housing; a scale disposed within the housing; a sensor unit disposed within the housing facing the scale with a gap between the sensor unit and the scale, the sensor unit being configured to scan the scale and obtain position information; at least one adjustment hole for a gap adjustment disposed in at least one of the housing and an end cover of the housing at a position corresponding to a position of the gap; and a removable cover on the at least one adjustment hole, wherein the at least one adjustment hole is configured such that a gap gauge is insertable into the gap between the scale and the sensor unit through the at least one adjustment hole when the cover is removed.
