自己診断機能センサ。[Claims for Utility Model Registration] An operation signal output means that outputs an operation signal when an object constituting a controlled machine is detected, and constant monitoring to see whether the operation signal output means is functioning normally. and internal self-diagnosis means for outputting an abnormality signal in a form different from the operation signal when it is determined that the operation signal output means is not functioning normally, and superimposing the operation signal and the abnormality signal. A self-diagnosis function sensor characterized by having an output means for outputting the output to the outside.
