Product Overview
Banner Engineering QS18VN6AF300Q is a mechanically adjustable background suppression photoelectric sensor from the World-Beam QS18 family. It uses a visible red LED to detect objects within a user-set cutoff range of 30 mm to 300 mm, ignoring everything beyond that point — including close, reflective backgrounds. Output is NPN (sinking) complementary, supporting both light-operate and dark-operate modes. Connection is via an M8 (Pico-style) 4-pin quick-disconnect — a mating cable is required and is not included. Rated IP67 / NEMA 6 for dust and washdown environments. Operates on 10V to 30V DC.
Key Features
- Sensing range: 30 mm to 300 mm, mechanically adjustable (multi-turn screw)
- Output: NPN (sinking) complementary — light-operate and dark-operate selectable
- Supply voltage: 10V to 30V DC
- Connection: M8 (Pico) 4-pin quick-disconnect — mating cable sold separately
- Light source: Visible red LED
- Environmental rating: IP67 / NEMA 6 — dust-tight and submersion-resistant
- Ignores reflective backgrounds beyond the set cutoff — reduces false triggers
Applications
- Object detection on packaging and bottling lines where backgrounds are close or reflective
- Material handling conveyors requiring precise part presence detection
- Automated assembly cells with tight sensor-to-background clearance
- Washdown or high-moisture environments rated for IP67 exposure
Frequently Asked Questions
Is this an NPN or PNP sensor? Will it work with my PLC?
This is an NPN (sinking) output sensor. Many North American PLCs use PNP (sourcing) input cards. Verify your input card type before ordering — a converter may be required if your system is PNP-only.
What connector does this sensor use?
M8 (Pico-style) 4-pin quick-disconnect. This is smaller than the M12 (Euro) connector common on many Banner sensors. Confirm your cabling matches M8 — a mating M8 cable is required and is not included with this unit.
What is the difference between this model and the QS18VN6AF300 or QS18VN6AF300Q5?
The QS18VN6AF300 has a 2-meter built-in cable — no connector. The QS18VN6AF300Q5 uses an M12 (Euro) 4-pin connector. This unit, the QS18VN6AF300Q, uses the M8 (Pico) 4-pin connector.
Will this work in a washdown environment?
Rated IP67 / NEMA 6 — sealed against dust and temporary submersion. Verify your specific wash-down pressure and chemistry requirements against the Banner datasheet before installation in food-grade or high-pressure rinse applications.
The QS18VN6AF300Q is a discontinued Banner model. Verify the datasheet against your cutoff distance and NPN input requirements before purchase.
