3.2 MountingGuidelines
Our sensors ship with modular mounting options. The sensor can be mounted in any orientation.
Propermountingwillensureoptimalsensorperformance,reducingnoisefromvibrationandproviding
efficientheat dissipation.
Mount toamaterialwith high thermal conductivity. The followingare recommendedaluminum
alloysandtheir thermalconductivity:
1) 6061: 167W/m-K
2) 7075: 130W/m-K
3) 2024: 121W/m-K
Ensureinterfacesareclean andfreefromdebris.
M3 screws are recommended formounting the sensor. The screw hole pattern in presented in
theSensordrawingaboveSensor Components.
Torque bolts appropriately for the mount material and bolts. A torque of 146cNm is recom-
mendedfora2stainlesssteelscrews.

Ensure your implementation maintains the base and top of the sensor at no greater than 25ºC
