We are working with SEN-14728 load cell and are having instances where the lead wires are breaking off from the body of the load cell. This is being handled with reasonable care but this issue still happens. Can you please advise what is causing this issue.
Additionally, what is the purpose of the epoxy on the load cell? Is this for strain relief to prevent wires from being pulled off or is this some sort of weather-proofing ?

Generally the load cells are stationary in most applications; if you are moving them often, even with care, expect wires that thin to be fragile throughout :-/
Yes the epoxy is for both stain relief and to keep moisture out; I’d say go ahead and try making additional strain relief for the wires with a loom/bracket/other support. Lots of hot glue, gorilla glue, etc should work…or heat shrink + loom, etc
The parts that had the broken wires had the epoxy peeled away from the body of the load cell, no longer providing support for the wires.
Do you have any other epoxy that you can use the will provide more structure to the part?
Also, is there a similar product that uses a larger gauge wire but had the same load cell?
Please advise.
The wires and supporting adhesives must be protected from hazards like pulls, repeated or excessive flexing, moisture ingress. Some load cells have better environmental protections (for example, hermetic or hi temp) and strain reliefs, but all will be vulnerable, to some extent, at the cable. It’s safe to predict that NONE will be as attractively priced as a SEN-14728.
