The following form is for returning parts to ACI’s factory in Middleton, Wisconsin.  Any item(s) shipped to us should be accompanied with an ACI generated RMA.  Your ACI Sales Representative can help you locate this information or walk you through the return process if you are unfamiliar with it.

If you are returning a part based on a factory error, we wish to apologize in advance for this inconvenience.  Rest assured that every RMA situation is treated as a high priority.  Our Technical Support staff excels at troubleshooting sensor issues and many times can help resolve an issue prior to initiating an RMA.
