CMF37 ABS Plastic Dustproof Capacitive Proximity Sensor with CE

ABS Plastic DC Dustproof Capacitive Proximity Sensor , Inductive Proximity Switch CMF37 CE

Working Principle of capacitive proximity sensor

Structural Category

Object-Inductive surface-RC oscillator-Switching stage-Magified output stage

CM12 Copper shell NPN PNP NO NC IP54 DC6 - 36V Capacitive proximity sensor

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.
When connecting to power supply, RC oscillator does not work. When an object is clos eto 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 d etermined by material dielectric constant, the more
dielectric constant, the more action distance will be obtained.

Outward appearance illustration

When an object approaches, the current consumption of
capactiance proximity switch will increase proportionally.

The dielectric constants foe some important materials are as below:

Features:

1) Multiplicity appearance
2) Compact volume
3) High repeat orientation precision
4) Many output form
5) Strong protection distribution
6) High on-off frequency commonly 600Hz
7) Wide voltage range
8) Dustproof, vibration-proof, waterproof and oil-proof
