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.
Rectangular Type:
Tubular Anti-bending Type:

Unlike contact-based sensors, proximity sensors have high resistance to temperature, humidity, and dust. 
Refer to the specification for detailed environmental tolerances.
Rectangular Type:
Tubular Anti-bending Type:

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.

Yes, but in environments with high vibration or impact, the detection distance should be selected with a safety margin. 
Follow installation torque guidelines to prevent loosening due to vibration.

The operating temperature is around -20℃ to + 60℃

Capacitive sensors can detect the presence of liquids.

Some models support remote monitoring via IO-Link or other communication protocols.

It is used for power distribution and electrical connections in various devices and machinery.

Yes, depending on the model, it can connect single-core or multi-core cables.

Yes, it can connect both input and output wiring.

Yes, most terminal blocks come with label slots for easy identification.

Screw-type, clamp-type, and plug-in type connections.

Yes, some models allow parallel connections via bridging bars.

Grounding-type terminal blocks can be used if required.

Yes, but high-voltage-rated terminal blocks must be selected.

A switch controls circuit connections, enabling the start or stop of a device.

Typically 100,000 to 1,000,000 operations, depending on the model.

Except for limit switches, all switches feature waterproof designs.

Yes, please refer to the product "Pilot Light"  
Its light signal can display the operating status of the switch.

It depends on the circuit design, but DPST (Double Pole Single Throw) switches can support this function.
