No hassle resolution if there is an issue. Serving customers since 1999.
Product Overview
Banner Engineering QS18VP6LVQ8 is part of the WORLD-BEAM QS18 series - a compact, general-purpose photoelectric sensor in retroreflective configuration. It emits a visible red LED beam (630nm) toward a separate reflector and signals when an object interrupts that beam. PNP complementary solid-state output connects via a 4-pin M12 integral quick-disconnect. Rated IP67 and NEMA 6/4X for washdown and outdoor environments. A potentiometer provides sensitivity adjustment. Photos show the specific unit you will receive.

Applications
- Conveyor product detection and part counting in packaging and manufacturing lines
- Assembly verification on automotive and electronics production lines
- Presence sensing in food and beverage processing - IP67 rating supports washdown zones
- Logistics and warehouse gate detection where 6.5m range covers wide conveyor spans
- Makers and lab builders integrating industrial-grade presence detection into custom automation rigs - the M12 QD connector and 10-30VDC range make it straightforward to wire into standard bench supplies and Arduino or PLC setups
Frequently Asked Questions
Is a reflector included?
No. The QS18VP6LVQ8 is a retroreflective sensor and requires a separate Banner-compatible reflector to function. It is not included and must be sourced separately.
Is a cable included?
No cable is included. The sensor terminates in a 4-pin M12 male quick-disconnect. A compatible M12 female cordset is required and must be sourced separately.
Is the output PNP or NPN?
PNP - complementary solid-state. The NPN variant is the QS18VN6LVQ8. Verify your PLC or controller input card accepts PNP (sourcing) signals before ordering.
What power supply does this require?
10-30V DC. Standard industrial 12V or 24V DC supplies are both compatible.
Is this suitable for detecting clear or transparent objects?
No. Clear object detection is explicitly not supported by this sensor. Use a diffuse or polarized retroreflective sensor rated for clear object detection if that is your application.
A retroreflective sensor with 6.5 meters of range and a washdown rating is the kind of part that sits quietly in a panel for years doing exactly one job with no drama - whoever puts this one to work gets that reliability from day one.
