LM60: Sensor used on encapsulated assemblies with Duralco 132 Thermal conductive Adhesive

Marco Estrada
Prodigy 10 points
Part Number: LM60

Tool/software:

Is there any design limitation for LM60 sensors, where the sensor is installed and encapsulated using thermal adhesive like Duralco 132? 

What is the compatibility of these sensors with thermally conductive epoxy? I'm looking to encapsulate this sensor in a terminal lug 192210424 using Duralco 132 and would like to know if there is any restriction in materials or sensor performance when a potting compound

    It's not clear if this adhesive is electrically conductive. There are some thermally conductive epoxies on the market that are not electrically conductive, and they rely on keeping the metal particles far enough apart. It's a compromise in thermal performance. At any rate, you will not be able to bridge LM60's pins with an electrically conductive epoxy.

    Generally speaking, we see some small output shift due to encapsulation, but it is typically on the order of 0.1C or less. It shouldn't be a concern on a device like LM60 which has +/-2C accuracy specification. You would also need to abide by the absolute max storage temperature (150C) during cure, if any.

    thanks,
