Banner QS18VP6AF300 Background Suppression Sensor 30-300 mm

Mechanically adjustable background suppression to 300 mm

The QS18VP6AF300 is a PNP background suppression (BGS) photoelectric sensor in Banner’s QS18 range. A five-turn screw on the housing sets the cutoff distance anywhere between 30 and 300 mm; anything beyond the cutoff is ignored, so the sensor can pick out a part on a conveyor even when a shiny frame, wall or guard sits a few centimetres behind it.

It is a diffuse-mode device with a visible red 640 nm LED, so the spot can be seen on the target during setup. Banner’s text explains that background suppression works in most situations where object colour, position or the background vary, which is why this style is a common choice for packaging lines, pallet and tray detection and general material handling.

Technical specifications

Setting the cutoff

Setup is mechanical rather than teach-in: with the object in position, turn the cutoff screw until the amber LED switches. Because the clutch stops the screw at each end of travel, the adjustment cannot be forced beyond its limits. The datasheet shows performance curves and a configuration example, and it notes that for mirror-like objects the sensor should be mounted as close as practical and tilted so reflected light is directed away from the lens.

Banner points out that the minimum sensing range changes with the cutoff setting, from roughly 4 mm at short cutoffs up to about 10 mm near the top of the range, so very close objects should be checked on the bench before a fixed mounting height is chosen.

Ordering and electrical notes

Standard models carry a 2 m cable. Adding the W/30 suffix gives 9 m, Q gives a 150 mm cable with a 4-pin M8 connector and Q5 a 150 mm cable with a 4-pin M12 connector. QD models need a mating cordset, and mounting brackets are listed in the accessories chapter. The datasheet also prints a required overcurrent protection table by supply wire size, from 5 A for 20 AWG down to 0.5 A for 30 AWG, and states that supply leads smaller than 24 AWG must not be spliced.
