18 mm Barrel Sensor for Industrial Detection

The Banner T18SN6LQ is a self-contained retroreflective sensor built for discrete object detection in industrial environments. It operates on a 10-30 V dc supply and provides complementary NPN outputs for direct PLC integration. The non-polarized infrared beam reaches a maximum sensing distance of 2000 mm. This unit suits automation engineers who need a compact, barrel-style presence sensor.

Thermoplastic Housing with M12 Quick-Disconnect

The 18 mm barrel uses a thermoplastic body rated to IP67 and IP69, plus NEMA 6P, so it withstands high-pressure washdown and temporary immersion. An integral Euro-style M12 4-pin quick-disconnect allows rapid installation and cable replacement without rewiring the sensor body. Encapsulated electronics and Ecolab certification support hygienic and chemical-resistant applications. Operators who require a cabled gland entry or a metal housing will need a different model.

Potentiometer Adjustment and Health Monitoring

A built-in potentiometer lets technicians fine-tune the sensing threshold on site without external tools. A marginal-signal health output warns of lens contamination or misalignment before a process fault occurs. The sensor powers up in 100 ms and delivers a 3 ms response time with 750 µs repeatability for consistent timing. No remote teach, IO-Link or DeviceNet functions are included, so users needing networked parameterisation must select another series.

Questions about this item

What voltage range does the 10-30 V dc supply accept?

The sensor operates from 10 V dc to 30 V dc, so any supply within that window will power it correctly.

What clearance is required for the 18 mm barrel and M12 connector?

The housing is 18 mm in diameter and uses an integral M12 4-pin quick-disconnect; allow space for the connector and cable bend radius behind the barrel.

How do I set the sensing distance with the potentiometer?

Apply power, position the reflector at the desired distance up to 2000 mm, then turn the potentiometer until the output LED toggles; the common mistake is adjusting before the beam is aligned.
