5. Some notes when choosing CR Autonics series capacitive proximity sensors

Determine the purpose of measurement
•    Accurately determine the object to be measured (material, size, shape) to choose the appropriate sensor type.
•    Determine the measurement range (distance between sensor and object) required.
Processing speed and accuracy
•    Processing speed: Choose a sensor with a response speed appropriate to the object's movement speed (fast or slow).
•    Accuracy: Determine the level of measurement area accuracy needed (high or medium).
Environmental influence
•    Magnetic field environment: Check the measurement area for magnetic field interference from magnets or other devices. Select an anti-magnetic interference sensor if necessary.
•    Vibration environment: Select an anti-vibration sensor if the measuring area experiences vibration.
•    High temperature environments: Select sensors capable of operating in high temperature environments if necessary.
Another factor
•    Design: Choose a design suitable for the installation space (cylindrical, flat).
•    Output type: Select the appropriate output type for the control system (NPN, PNP, Analog).
•    Protection level: Select a sensor with an IP protection level appropriate to the environment (IP65, IP66, IP67).
Select the appropriate sensor
•    Based on the above factors, compare the technical specifications of different types of CR Autonics sensors to choose the type that best suits your needs.
•    Consult a technical expert if necessary.
