Type: Inductive Sensor

Detection Distance: 5mm/8mm

Detection Subject: Conductive, Electric Body

Type: PNP/ NPN

1.The induction surface of capacitance sensor is composed of two coaxial mental electctrodes, which from a capacitor and connected on RC oscillation circuit, just like an open capacitor electrode.
2.When connecting to power supply, RC oscillator does not work. When an object is close to capacitor electrode, the capacitor capacity will increase, and the oscillator will vibrate. Through the treatment of behind stage circuit, both signals of stop oscillation and oscillation will be converted to switch signs for checking the existence of object. this distance can be obtained, but to nonmetal object, the action distance is determined by material dielectric constant, the more dielectric constant, the more action distance will be obtained.

描述

Inductive proximity switch is composed of three parts:oscillator,switch circuit and magnified output circuit The oscillator will generate an alternating electric field.When the metal object approaches this electric field and reaches the induction distance, thirlpool will generate in metal object, resulting in attenuation of vibration and then stop.the change of vibration and stop of oscillator is treated by behind stage magnified circuit and converted to switching sign,triggering driving control for non-contact detection.
