Lanbao CR18XT-Y M18 8/12mm PTFE Capacitive Sensor

Lanbao CR18XT-Y M18 8/12mm PTFE Capacitive Sensor

Lanbao CR18XT-Y Series is an M18 corrosion-resistant capacitive proximity sensor for DC automation systems that need longer sensing distance in chemical-resistant or oil-resistant environments. It uses a white PTFE housing, 2m PUR cable, IP67 protection, and a cylindrical M18 body for non-contact detection where ordinary plastic housings may not be suitable.

This listing covers CR18XTCF08 and CR18XTCN12 DC variants. Store variants include 8mm quasi-flush and 12mm non-flush sensing options, NPN or PNP output, and normally-open, normally-closed, or NO+NC switching logic.

Integration Notes & Hardware Guidance

• Media compatibility: The PTFE housing and PUR cable are intended for corrosion-resistant and oil-resistant use, but actual chemical compatibility should be checked against the working fluid or cleaning agent.
• Distance selection: Choose CR18XTCF08 for 8mm quasi-flush mounting or CR18XTCN12 for 12mm non-flush sensing.
• Output selection: Match NPN or PNP wiring to the input type of your PLC, controller, counter, or I/O module before ordering.
• Signal logic: Choose DNOY normally-open, DNCY normally-closed, or DNRY NO+NC variants for NPN, and DPOY normally-open, DPCY normally-closed, or DPRY NO+NC variants for PNP.
• Installation check: Capacitive sensing depends on target material, size, moisture, grounding, surrounding material, and mounting position; test with the actual target before final commissioning.

FAQ

How is CR18XT-Y different from CR18XT?

CR18XT-Y offers longer M18 corrosion-resistant sensing distances, with 8mm and 12mm variants compared with the shorter 5mm and 8mm CR18XT options.

What sensing distances are available?

This listing includes 8mm quasi-flush variants and 12mm non-flush variants, with multi-turn potentiometer adjustment reference.

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 does NO+NC mean?

NO+NC variants provide both normally-open and normally-closed switching behavior, useful when the control design needs complementary outputs.

Can this sensor detect non-metal targets?

Yes. As a capacitive proximity sensor, it can detect many solid, liquid, or granular targets, but the effective distance depends on material properties and installation conditions.
