Square PNP Proximity Switch , PNP Proximity Sensor Good Anti Interference Ability

Square PNP Proximity Switch , PNP Proximity Sensor Good Anti Interference Ability

Description

These PNP Proximity Switches are used for sensing ferrous and non-ferrous metals at close proximity. Inductive proximity sensors are available in a wide variety of barrel diameters, lengths and configurations.

Three-wire PNP normally open DC

Working principle

The switch contains high-frequency oscillation circuit, detection circuit, amplifier circuit, the solution circuit and the output circuit. When the power is supplied to the switch, the oscillator in the high frequency oscillation circuit generates an alternating electromagnetic field on the detection surface of the switch. When there is a metal close to the switch detection surface, the eddy current inside the metal absorbs the energy of the alternating electromagnetic field in the oscillator. The oscillator is weakened or stopped. Oscillator energy changes in the two states, the detection circuit is converted to a level signal, through the amplifier circuit to amplify the level signal after the trigger circuit to trigger the output transistor transistor circuit to produce a switch signal. Thereby detecting the presence or absence of the metal. To achieve the purpose of metal detection.
