The principle of an E2E proximity switch is as follows: 1. The proximity switch contains a high-frequency transmitter that causes the coil to emit a high-frequency magnetic field. 2. When the object being measured approaches the high-frequency magnetic field, eddy currents are generated on the surface of the object, and these eddy currents in turn generate a magnetic field. 3. The transmitter stops vibrating due to the magnetic field generated by the eddy currents. 4. The presence or absence of vibration controls the control output to ON/OFF.
Features:
• Response frequency increased by 60%.
