User Manual

Warning: The water ingress protection rating for the sensor is only valid if the I/O cable is plugged
into the panel mount connector on the base of the sensor, and the locking collet rotated past the
détente 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 the connected cable 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 cable
immediately adjacent to the plug over mold may create a moisture ingress path into the connector.
Please note the cable minimum bend radius requirements below:
3.2 Mounting Guidelines
Our sensors ship with modular mounting options. The sensor can be mounted in any orientation.
Proper mounting will ensure optimal sensor performance, reducing noise from vibration and providing
efficient heat dissipation.
Mount to a material with high thermal conductivity. The following are recommended aluminum
alloys and their thermal conductivity:
1) 6061: 167 W/m-K
2) 7075: 130 W/m-K
3) 2024: 121 W/m-K
Ensure interfaces are clean and free from debris.
M3 screws are recommended for mounting the sensor. The screw hole pattern in presented in
the Sensor drawing above
Sensor Components.
Torque bolts appropriately for the mount material and bolts. A torque of 146cNm is recom-
mended for a2 stainless steel screws.
Use TIM (Thermal Interface Material) for any irregular or unmachined surfaces.
Do not overconstrain the sensor if mounting to both the top and the bottom.
Use a thermally conductive pad to ensure good conductivity while not over constraining.
Ensure your implementation maintains the base and top of the sensor at no greater than 25ºC
above ambient with an ambient less than 50ºC.
The shape of any heatsink should maximize the surface area for free and forced convection while
being thick enough to allow the heat to conduct through the material.
