Compare the picture of this capacitive prox to the inductive prox in the section above note that you wouldn t be able to tell which sensor was inductive or capacitive just by looking at them.
Proximity sensor and limit switch difference.
We offer one of the broadest line in the industry including proximity and photoelectric sensors limit switches and safety switches and rfid and operator safety devices.
Cylindrical proximity sensors and switches use infrared acoustic capacitative or inductive means to detect objects and will open or close the electrical circuit if the object is within a certain distance.
This makes them ideal for use in dirty or wet environments.
Proximity sensors detect the presence or absence of objects using electromagnetic fields light and sound.
Due to the internal contacts the working life is relatively shorter.
Sensor targets sense distance typ.
Proximity sensors includes all sensors that perform non contact detection in compassion to sensors such as limit switch that detects the object by physically contacting them.

The difference between limit switch and proximity sensor.
Capacitive proximity sensors are another type of prox switch that are commonly used in industrial automation.
Prox switches are less sensitive to dust moisture moisture and oil than limit switches and their internal solid state circuitry makes them better suited for applications with high levels of vibration than the mechanical limit switches.
There are many types each suited to specific applications and environments.
Sensors and limit switches eaton s mission is to improve the quality of life and the environment through the use of power management technologies and services.
Proximity sensors operate without any physical contact from the object itself.
A proximity sensor detects objects when the objects approach within the detection range and boundary of the sensor.

Limit switches are contact switches.
Limit switches are used for position detection in one direction.
