Abstract
A demand for downsizing of a multiple optical-axis photoelectric sensor can be coped with, and various state displays are performed. An inter-optical-axis indication unit is arranged between two adjacent optical axes so as not to interfere with the optical axis located in a lower end portion of a receiver. The inter-optical-axis indication unit is capable of displaying at least one piece of information out of a control input state, a safe special function state, a synchronization type, and an interlock state.
