Warning: Water ingress protection: The sensor ingress protection rating is only valid if the I/O
cable is pluggedinto the panel mount connector on thebase of the sensor,and the locking collet
rotated past the detent click to the properly locked condition i.e past the détente position. The
cable and plug are an element of the sensor ingress protection system. Without this the ingress
protection rating may be compromised. Bending the cable at a sharp angle directly after egress
from the plug over mold should also be avoided. Sharp bends and high axial stresses on the ca-
ble immediately adjacent to the plug over mold may create a moisture ingress path into the the
connector. Pleasenote thecable minimumbendradiusrequirementsbelow:

12.2 MountingGuidelines

mance,reducingnoise fromvibrationand providingefficient heatdissipation.
Mount toa material with high thermal conductivity. The following arerecommended aluminum
alloysandtheir thermalconductivity:
1) 6061: 167W/m-K
2) 7075: 130W/m-K
3) 2024: 121W/m-K

UseTIM (ThermalInterfaceMaterial)foranyirregularor unmachinedsurfaces
Donot overconstrainthe sensorif mountingtoboth thetopand thebottom
Usea thermallyconductive padto ensuregood conductivitywhile notoverconstraining.
Ensure your implementation maintains the base and top of the sensor at no greater than 25ºC
