Adjustable-field laser sensor

The Banner QS18VN6LAF250 is a Class 2 visible-red laser photoelectric sensor with background-suppression that can be set mechanically between a 20 mm cutoff and a 250 mm maximum range. It operates on 10-30 V dc and switches an NPN output with a 0.7 ms response time. A 2 m integral cable connects the ABS housing rated IP67 and NEMA 6. The 658 nm beam produces a small visible spot for precise alignment.

Installers needing short-range precision

This sensor suits applications that require reliable detection of objects at distances up to 250 mm while ignoring background surfaces beyond the adjustable cutoff point. It is not intended for long-range presence sensing beyond a quarter metre, nor for installations that demand PNP switching logic or a quick-disconnect connector. The fixed cable and NPN output limit use in systems wired exclusively for PNP or plug-in modularity.

Adjustable background suppression to 250 mm

The single specification that determines fit is the mechanically adjustable background-suppression range, which lets the installer set the cutoff anywhere between 20 mm and 250 mm. If the target must be detected at a known distance within that window while a closer or farther background is ignored, this sensor matches the requirement; if the needed cutoff falls outside those limits, a different sensing principle is required.

Questions about this item

How do I choose between the available sensing ranges for this Banner QS18VN6LAF250 sensor?

The sensor offers an adjustable cutoff point between 50 mm and 250 mm with a 20 mm minimum range, so you select the exact distance needed for your application using the mechanical screw adjustment.

What does the 250 mm maximum sensing distance mean when the sensor is installed?

It indicates the farthest adjustable cutoff point for background suppression; the sensor will ignore objects beyond this set distance while detecting targets within the 20 mm to 250 mm range.

What does the NPN output with 10-30 V dc supply cap in practice?

The NPN output switches the load to ground within the 10-30 V dc supply range, with a 0.7 ms response time and 130 µs repeatability for discrete detection tasks.
