Inductive Proximity Sensor Detection Switch SN04-N NPN DC 10-30V

Description:

Corner General – Purpose Proximity Switch
Inductive Proximity Switches SN04N SN04P SN04Y NPN DC 3-wire embedded
Proximity switch (also known as non-contact stroke switch) is the role of close to the metal when the action is widely used in machine tools and other equipment control purposes.

Working Principle:

The proximity switch consists of three main components: an oscillator, a switching circuit, and an amplified output circuit. The oscillator produces an alternating magnetic field. When the metal target is close to this magnetic field and reaches the sensing distance, eddy currents are generated in the metal target, resulting in oscillation decay and even stop vibration. Oscillator oscillation and vibration changes are processed by the post-amplifier circuit and converted into a switch signal to trigger the drive control device, so as to achieve non-contact detection purposes. The closer the target is to the sensor, the closer the target is closer to the sensor, the greater the damping in the coil; the larger the damping, the smaller the current of the sensor oscillator. The current loss of the inductive proximity switch, as the distance from the metal target decreases And reduced.

The difference between normally open (NO) and normally closed (NC)

First, normally open (NO) is the normal state of the signal output line is off, no signal output, when the sensor is turned on, the output signal.
Second, normally closed (NC) is the normal state of the signal output line is closed, continuous signal output, when the sensor is turned off, turn off the signal.
