Lanbao CR12S M12 2/4mm Plastic Capacitive Sensor

Lanbao CR12S M12 2/4mm Plastic Capacitive Sensor

Lanbao CR12S Series is an M12 plastic cylindrical capacitive proximity sensor for non-contact object detection in compact industrial installations. Compared with the metal-housing CR12 series, the CR12S uses a PBT housing while keeping the same M12 form factor, adjustable sensing-distance options, and DC output configurations.

This listing covers CR12SCF02 and CR12SCN04 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 CR12 Metal Series, Lanbao CR18S Series, and Lanbao CR18 Series. For adjustable Y-series options, see the Lanbao CR12X-Y Series.

Integration Notes & Hardware Guidance

• Sensing-distance selection: Choose CR12SCF02 for 2mm flush mounting or CR12SCN04 for 4mm non-flush sensing distance.
• Housing selection: Choose CR12S when a PBT plastic M12 housing is preferred over the metal CR12 housing.
• 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.
• 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 is the difference between CR12S and CR12?

The CR12S series uses a PBT plastic M12 housing, while the CR12 series uses a metal M12 cylindrical housing.

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 CR12S Series need adjustment after installation?

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