PMJ9100S1 should be mounted flat and parallel to the media to be tracked, spaced with the gap z shown in figure 2 . module outline drawing . the z height is the assembly height measured (with reference to the optical center) from the lens flange (termed as lens reference plane) to the tracking surface. ? PMJ9100S1 should be mounted such that the longer axis of the module is aligned to the direction of media movement to be tracked, at either at 0 or 180, with deviations of less than 0.5. refer example shown in figure 4. mounting direction . ? it is recommended that the two guide posts on the bottom of PMJ9100S1 be utilized to aid the positioning of the module via corresponding guide holes on the baseplate. ? in addition, PMJ9100S1 should be secured to the baseplate with m2 screws through the two holes on the flange of th e lens . ? take note to ensure module misalignments during assembly do not exceed the specifications stated in table 3 . recommended operating conditions . ? parameter h1 to h4 in figure 5. type of assembly misalignments refer to the distance from the edges of the lens to the tracking surface. figure 4 . mounting direction pixart confidential
