Connector Material Issue and Replacement Plan
The products Cycle-PO4, WQM, and HydroCAT with serial number ranges outlined in the table below have electrical bulkhead connectors potentially affected by a change in material by our supplier. The failure mode includes corrosion and weakening of the pins, especially the power pin, which may result in pins breaking and getting stuck inside cables (failure will not cause flooding). Failure is most frequently seen in units in shallow/warm water that are connected to external power.
If your sensor is in the affected range, please see the attached photos of “affected” and “OK”connectors. If you think your connector is affected, contact email@example.com to schedule replacement of your connector. Sensors are currently being built with validated connectors that are unaffected by the issue; the supplier has discontinued use of the material.
