Capacitive proximity sensors can be used to detect metallic and also nonmetallic targets like paper, wood, plastic, glass, wood, powder, liquid..etc without physical contact. The capacitive proximity sensor works on the capacitor principle. The main components of the capacitive proximity sensor are plate, oscillator, threshold detector, and the output circuit.
The plate inside the sensor acts as one plate of the capacitor and the target acts as another plate and the air acts as the dielectric between the plates. The capacitive sensor can detect any targets whose dielectric constant is more than air.
It can detect both metallic and non-metallic targets.
Good stability.
High Speed.
Good Resolution.
Capacitive sensors are good in terms of power usage.
Low cost.
Detect various materials including metal, iron, stone, plastic, water, and grain.
Long life cycle and reliable performance.
Built-in surge protection circuit, reverse polarity protection circuit (DC types).
Built-in surge protection circuit (AC types).
The Built-in sensitivity adjuster for convenient configuration.
Operation indicator (red LED).
Ideal for level detection and position control.
