Separate type photoelectric switch

A separate type photoelectric switch which detects an object in a detection area, said separate type photoelectric switch comprising:

• a head having a light projector which projects a light to said detection area, and a light receiver which receives the light from said detection area and outputs a light reception signal based on the received light;
• a main body being formed separately from said head and having a processor which detects the object in said detection area on the basis of the light reception signal;
• and
• a power supply circuit for supplying said head with a power voltage for driving said head, the power voltage being a voltage representative of information on an operation of said head,
• wherein said head includes an operating portion for performing a predetermined operation in accordance with the information represented by the voltage supplied from said main body.

A separate type photoelectric switch which detects an object in a detection area, said separate type photoelectric switch comprising:

• light receiving means for receiving light from said detection area and outputting a light reception signal based on the received light;
• and
• processing means separate from said light receiving means for detecting the object in said detection area on the basis of the light reception signal,
• wherein said light receiving means includes an indicating means for displaying information regarding the detection of the object executed by said processing means.
