Autonics CR18-8DP DC10~30 8mm M18 Capacitive Proximity Sensor PNP-NO (Shielded)

Capacitive proximity sensors operate based on the capacitor principle. The sensor contains a plate that acts as one plate of a capacitor, with the target acting as the other plate, and air serving as the dielectric. As a target approaches the sensor plate, the capacitance increases, and as it moves away, the capacitance decreases. The sensor's detector circuit monitors the oscillator's amplitude output and switches the output based on these changes. This allows the detection of any targets with a dielectric constant greater than air.

• Avoid Extreme Conditions: Do not use the sensor beyond the specified temperature and voltage ranges to prevent damage.,
• Prevent Overloading: Ensure the output current does not exceed 200 mA to avoid sensor overload and potential failure.

• Check Compatibility: Ensure the target material's dielectric constant is higher than air for effective detection.,
• Use Protection Features: Utilize the built-in surge and reverse polarity protection circuits to safeguard the sensor.,
• Adjust Sensitivity: Use the built-in sensitivity adjuster to optimize the sensor for specific applications.

• Range: -25 to 70°C
