Lanbao CR18 M18 5/8mm Capacitive Proximity Sensor

Lanbao CR18 M18 5/8mm Capacitive Proximity Sensor

Lanbao CR18 Series is an M18 metal cylindrical capacitive proximity sensor for non-contact object detection. Compared with the smaller CR12 housing, the CR18 format provides longer adjustable sensing distance while keeping a compact threaded body for industrial machine installation.

This listing covers CR18CF05 and CR18CN08 DC variants with 5mm flush or 8mm non-flush adjustable rated sensing distance. Store variants include NPN or PNP output, normally-open, normally-closed, or NO+NC output logic, and either fixed 2m PVC cable or E2 M12 connector wiring.

For related Lanbao capacitive sensors, compare the Lanbao CR12 Series, Lanbao CR18S Series, and Lanbao CR30 Series. For adjustable Y-series options, see the Lanbao CR18X-Y Series.

Integration Notes & Hardware Guidance

• Sensing-distance selection: Choose CR18CF05 for 5mm flush mounting or CR18CN08 for 8mm 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, normally closed, or NO+NC 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 CR18 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 5mm adjustable flush variants and 8mm 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.

When should I choose the CR18 instead of the CR12?

Choose the CR18 when you need a larger M18 housing and longer adjustable sensing distance than the smaller M12 CR12 series.
