Proximity sensors are categorized into electromagnetic field sensors and capacitive effect sensors, which detect the presence or approach of an object without physical contact. They replace traditional contact-based detection methods such as limit switches. The principle involves converting the movement or presence of a detected object into an electrical signal. Detection methods include:
Electromagnetic induction: Generates eddy currents on metal objects for detection.
Capacitive sensing: Uses the electrostatic coefficient on an object's surface for detection.

Depending on the model, the detection range introduced by MEAN WELL is 1~18mm.

Ensure correct object size, detection distance, material, and installation environment (embedded or exposed installation). Refer to the specification (Rectangular Type LINK, Tubular Anti-bending Type LINK )for model selection and follow installation guidelines.

Sensitivity refers to the sensor's ability to react to target objects, which can usually be adjusted to fit different applications.

Inductive proximity sensors are specifically designed to detect objects containing metal.

Typically, inductive sensors only detect metal. For non-metallic objects, consider capacitive, optical, ultrasonic, or fiber-optic sensors for detection.

Use high-frequency sensors with a fast response rate.

Yes, but proper selection based on the specification is required.

Sensors provide either digital (switching signals) or analog (voltage/current) signals, with most using digital outputs (NPN / PNP).

By using directional design and background suppression functions.

Inductive sensors detect metal objects (e.g., steel, aluminum, brass, copper).Capacitive or optical sensors can differentiate between metals, resins, liquids, powders, etc. (Note: Inductive sensors have varying detection ranges depending on metal composition.)

The number of detection outputs per second when a standard target repeatedly approaches the sensor.
