Photoelectric sensor and detector terminal module therefor

摘要

A module from which photoelectric sensors of different types with different functions can be constructed is integrally formed with an optical assembly and a detection circuit assembly. The optical includes a lens and its holder and the detection circuit assembly and includes an integrated circuit and terminals connected to it. The integrated circuits include different circuits with various functions such as a detection circuit for detecting presence or absence of a target object of detection. The terminals include input and output terminals for passing signals to and from selected ones of these circuits depending on the desired functions of the photoelectric sensor to be formed by using the module.
