Claims (1)

[Scope of utility model registration request] A sensor section that has a switch element that opens and closes when an object is detected, a power input terminal, a ground terminal, and a signal output terminal, and an interface that has a comparator that takes a binary state, a power output terminal, a ground terminal, and a signal input terminal. each end of the interface part is separably connected to each end of the sensor part via a connector, and the signal input end of the interface part is connected to the sensor part side. In the object detection device, the state of the comparator is reversed when the comparator is connected to the ground (or power source) via the switch element, the sensor section includes a circuit for connecting to the ground (or power source). A resistor is provided therein, and the interface section is also provided with another comparator that is connected to the signal input terminal and assumes a binary state, and this comparator An object characterized by operating in such a way that the output state when the signal input terminal connected to the ground (or power supply) is different from the output state when the signal input terminal and the ground (or power supply) are short-circuited. Detection device.
