Lanbao CR12 M12 2/4mm Capacitive Proximity Sensor

Lanbao CR12 M12 2/4mm Capacitive Proximity Sensor

Lanbao CR12 Series is an M12 metal cylindrical capacitive proximity sensor for non-contact object detection. Unlike inductive sensors that focus on metal targets, capacitive sensing can detect conductive and non-conductive materials when the sensing distance and installation conditions are correctly matched.

This listing covers CR12CF02 and CR12CN04 DC variants with 2mm flush or 4mm non-flush adjustable rated sensing distance. Store variants include NPN or PNP output, normally-open or normally-closed output logic, and either fixed 2m PVC cable or E2 M12 connector wiring.

For related Lanbao capacitive sensors, compare the Lanbao CR12X-Y Capacitive Sensor, Lanbao CR12S Series, and Lanbao CR18 Series. For a larger M30 capacitive option, see the Lanbao CR30 Series.

Integration Notes & Hardware Guidance

• Sensing-distance selection: Choose CR12CF02 for 2mm flush mounting or CR12CN04 for 4mm non-flush sensing distance.
• Material behavior: Capacitive sensing depends on target material, size, grounding, moisture, and installation conditions; test the actual target before final installation.
• Output selection: Match NPN or PNP wiring to the input type of your PLC, controller, counter, or I/O module before ordering.
• Logic selection: Choose normally open or normally closed based on the required signal state when the target is detected.
• Connection choice: Select fixed 2m PVC cable versions for direct wiring or E2 M12 connector versions when quick replacement and standardized cables are preferred.

FAQ

What does the Lanbao CR12 Series detect?

It is a capacitive proximity sensor designed for non-contact object detection, including materials that may not be detected by standard inductive metal sensors.

What sensing distances are available?

This listing includes 2mm adjustable flush variants and 4mm adjustable non-flush variants.

How do I choose between NPN and PNP?

Choose the output type required by your controller input. NPN and PNP wiring are not interchangeable unless the receiving device supports both input standards.

What is the difference between cable and E2 versions?

Cable versions use a fixed 2m PVC cable, while E2 versions use an M12 connector for detachable wiring and easier sensor replacement.

Does the CR12 Series need adjustment after installation?

Because capacitive sensing is affected by material and mounting conditions, practical sensitivity verification and adjustment are recommended after installation.
