Patent ID: 6987260

Claim:
A detection terminal module for a photoelectric sensor, said detection terminal module comprising: an optical assembly including a lens and a holder which holds said lens; and a detection circuit assembly which is integrally formed with said optical assembly and includes an integrated circuit and terminals connected to said integrated circuit; wherein said integrated circuit includes: a detection circuit for detecting presence or absence of a target object of detection for said photoelectric sensor from a light-reception signal obtained by converting light received through said lens into an electrical signal by a light receiving element, a self-analysis circuit for judging the signal level of said light-reception signal by comparing the signal level of said light-reception signal with a specified threshold value, and a judging circuit for judging presence or absence of light entering said light receiving element or operating condition of said photoelectric sensor inclusive of result of judging by said self-analysis circuit; said terminals including: a control output terminal for transmitting outputs of said detection circuit, a stability display terminal for transmitting outputs of said self-analysis circuit, an indicator terminal for transmitting outputs of said judging circuit, a sensor power source terminal for supplying power for said integrated circuit, and a GND terminal for keeping said integrated circuit at the zero voltage level; wherein said module serves to form sensor products of different kinds by connecting electrically through said terminal to an output circuit provided external to said detection circuit assembly.
