Pro-Range CLJ-C17-5ANB NC NPN Inductive Proximity Sensor, 5mm Detection Distance, 17x17mm Body

This sensor has an NPN Normally Closed (NC) output. In a typical 3-wire DC configuration, connect the brown wire to positive DC voltage (commonly 10-30V DC), the blue wire to negative/common ground, and the black wire is the signal output. When no target is present, the output is 'on' (connected to ground via the NPN transistor). When a metal target is detected within 5mm, the output switches 'off' (open circuit). Always ensure your load (e.g., PLC input) is connected between the positive supply and the black output wire.

No, inductive proximity sensors like the CLJ-C17-5ANB are specifically designed to detect conductive metals only. They work by generating an electromagnetic field and sensing the eddy currents induced in a metal target. Non-conductive materials such as plastic, wood, glass, or liquids will not affect the field and therefore will not be detected. For non-metallic objects, a capacitive proximity sensor would be required.

While a specific voltage isn't listed in the provided specs, industrial NPN inductive sensors like this typically operate on a 10-30V DC supply. This model includes built-in polarity protection, which prevents damage if the power wires are accidentally reversed, and short-circuit protection on the output, which safeguards the internal switching transistor if the output is directly shorted to ground or supply.
