Product Overview
Banner Engineering QS18VP6DQ8 is a self-contained diffuse-mode photoelectric sensor from the WORLD-BEAM QS18 series. It detects objects without a reflector or separate receiver by emitting a visible red LED beam and triggering on the return signal. Rated sensing range is 450 mm. Output is PNP complementary, providing both Light-Operate and Dark-Operate modes. Connects via 4-pin M12 Euro-style quick-disconnect fitting.
Key Features
- Sensing mode: Diffuse (proximity) - no reflector required
- Sensing range: 450 mm (approx. 18 inches)
- Output: PNP complementary (Light-Operate and Dark-Operate)
- Supply voltage: 10-30V DC
- Connection: 4-pin M12 Euro-style quick-disconnect (Q8)
- Beam type: Visible red LED
- Environmental rating: IP67, NEMA 6
Applications
- Presence/absence detection on conveyor lines where mounting a reflector opposite the sensor is not feasible
- Part detection in automated packaging and bottling lines
- Object counting and position sensing in material handling systems
Frequently Asked Questions
What power supply and wiring does this sensor require?
The QS18VP6DQ8 requires a 10-30V DC supply. Connection is via a 4-pin M12 Euro-style female cordset, not included. The output is PNP (sourcing) - verify your control system accepts PNP logic before ordering.
Is this compatible with NPN control systems?
No. This unit outputs a PNP signal. The NPN equivalent is the QS18VN6DQ8. These two variants are not interchangeable.
Can this sensor be used in through-beam or retroreflective mode?
No. It is a diffuse-mode sensor only. Through-beam and retroreflective applications require a different sensor type.
Does target color affect sensing range?
Yes. Diffuse sensors rely on reflected light. Dark or low-reflectivity targets will reduce effective sensing range below the rated 450 mm. If the background is more reflective than the target, consider a background-suppression sensor instead.
The QS18VP6DQ8 is a current Banner Engineering part number. Datasheet and dimensional drawings are available directly from Banner Engineering's website for installation planning.
