الأسئلة المتداولة
What is an inductive proximity sensor?
Similar to the inductive proximity sensor, capacitive proximity sensor is also a non-contact proximity switch that senses the presence of an object without touching it. The object can be a metallic or non-metallic solid, liquid, or powder.
It works by generating an electrostatic field around its sensing surface. When an object enters this field, it disrupts the field, changing the capacitance of the system. An oscillator circuit within the sensor detects this change in capacitance and triggers an output.
If you would like to know how it works in detail, please refer to our blog: How Capacitive Proximity Sensors Work: The Ultimate Guide.

How many types of capacitive proximity switch?
According to the output differences, the capacitive sensor can be divided into PNP or NPN types.
According to the wire differences, it can be categorized into 2 wires, 3 wires and 4 wires types.
If classified by output types, the capacitive proximity sensor can be digital output type and analog output type.
Capacitive proximity switch applications
Capacitive proximity switches can be used in fluid level detection in a plastic or glass container, material level detection, fracture inspection, plastic or glass bottle counting, conveyor belt tightness alarm and so on.
What is the difference between a capacitive and inductive proximity sensor?
