Proximity switch : ( Wing brake is used for position control). There are 3 lines in total, including 2 power
input, brown + 12V, blue: GND and 1 signal output. When the sensing head touches a magnet or metal
object (sensing distance is 2-4mm), the output is + 12V, otherwise it is 0V.
Motor: The load current of DC24 V DC motor is about 300 Ma, and the load current is less than 1.2 A.
Cylindrical photoelectric switch: (the same as alarm and anti-pinch signal detection) is composed of a
transmitter and receiver. The transmitter has 2-wire power input (brown + 12V, blue: GND), and the power
supply indicator is normally on; at the receiving end, there are two line power input (brown + 12V, blue:
GND) and one line signal output (black line). When the area is accessible, that is, when the area is isolated,
there is signal output The indicator lights up and outputs + 12V, otherwise it is 0V.
