The 330103-00-18-10-02 Proximity sensor is a non-contact sensor capable of detecting the proximity and presence information of an object and converting it into an electrical signal. This sensor is commonly used in automated control systems, such as machine tools, metallurgy, chemical, textile and printing industries, as a limit, counting, positioning control and automatic protection links.

330103-00-18-10-02 The working principle of the proximity sensor is mainly based on the sensitivity of the displacement sensor to the approaching object. According to the different detection methods, proximity sensors can be divided into inductive, capacitive and ultrasonic types.

Inductive proximity sensors detect the proximity of objects by changing the magnetic field strength of the coil. When a metal object approaches the sensing area of the sensor, it changes the inductance of the coil, which changes the output signal of the sensor. Such sensors are commonly used to detect ferromagnetic and non-ferromagnetic objects.

Capacitive proximity sensors detect the proximity of objects by detecting changes in capacitance. When a conductor object approaches the sensing area of the sensor, it changes the capacitance of the sensor, thus changing the output signal of the sensor. Such sensors are usually used to detect conducting objects.

Ultrasonic proximity sensor is the use of ultrasonic reflection and propagation characteristics to detect the proximity of objects. When an object approaches the sensing area of the sensor, it will reflect the ultrasonic wave and change the propagation time or intensity of the ultrasonic wave, thus changing the output signal of the sensor. Such sensors are commonly used to detect the distance and presence of objects.

In general, the 330103-00-18-10-02 proximity sensor is an efficient and accurate non-contact detection method, with long service life, reliable operation, high repeated positioning accuracy, no mechanical wear, no spark, no noise, strong vibration resistance and other characteristics.
