Fiber Optic Sensor, NPN/PNP, NO/NC

Fiber optic sensor, also known as fiber senor or fiber amplifier. It sends the optical signal from the light source to the modulator through the optical fiber, so that the measured parameter interacts with the light entering the modulation area, resulting in the optical properties of the light (such as light intensity, wavelength, frequency, phase position, polarization state, etc.) changed. Then the changed modulated signal source will be sent to the optical detector through the optical fiber. After demodulation, the measured parameter is obtained.

Applications: Fiber optic sensors are widely used in food, packaging, electronics and other automation industry. Fiber optic sensors are usually used for detection, counting and position control.
