3M™ MicroTouch™ DX123 Controller Mounting Hole Dimensions
Important Note:
Ensure that the two controller mounting holes are connected to the
chassis ground of the display. Ensure the star washers do not overlap the mounting hole
rings.
1.
We recommend you mount the controller board to the housing using metal screws in
the mounting holes nearest the sensor connection and the mounting hole nearest the
controller connection.
2.
Insert a metal thru-hole spacer between the controller board and the metal chassis as
shown in the following diagram. These spacers will prevent the pins and/or traces on
board from shorting to the chassis. Make sure the spacer diameter is less than the
screw head diameter.
