The Autonics PR18-5DP Details:

Type: Inductive Proximity Sensor.

Sensing Distance: 5mm (This is the maximum distance at which the sensor can reliably detect a metallic object.)

Output Type: PNP (Positive-Negative-Positive) - This means that the sensor provides a positive voltage output when it detects a metallic object.

Output State: Normally Open (NO) - This means the sensor's output is normally in an open circuit state (no current flows) and closes (current flows) when a metallic object is detected.

Supply Voltage: DC 10~30V - This is the range of voltage the sensor requires to operate. It can be powered with a direct current (DC) source between 10V and 30V.

Thread Size: M18 - This indicates the thread size of the sensor, which is M18. This is a standard metric thread size.

Shielding: Unshielded - This sensor is unshielded, which means it is designed for applications where the sensor is not surrounded by metal or other materials that could affect its detection capabilities. Unshielded sensors are suitable for general-purpose applications.
