QMT42 Series 400 mm Adjustable Field Sensors

Sensing Cutoff Point is Adjustable from 125 to 400 mm (5 to 16 in)

Printed in USA

P/N 49211K7A

• Adjustable field technology allows direct detection of objects within a

defined sensing field, while completely ignoring reflective objects located
beyond the sensing field cutoff point

• Reliable

electronic adjustment* of sensing field cutoff point from 125 to

400 mm; no mechanical adjustments to worry about

• Compact, rugged, low cost self-contained sensors in metal die cast

housings

• Epoxy-encapsulated circuitry; leakproof IP67 (NEMA 6) construction for

reliable sensing in harsh environments

• Outstanding electrical noise immunity

• Dual LED system indicates sensor performance

• Choice of integral cable or quick disconnect connector

* Patent Pending

Interpretation of Performance Curves

The percentage of deviation indicates a change in the cutoff point for either 18% gray or 6% black targets, relative to
the cutoff point set for a 90% reflective white test card.

As an example, the cutoff point decreases 10% for a 6% reflectance black target when the cutoff point is adjusted for
400 millimeters (16 inches) using a 90% reflectance white test card. In other words, the cutoff point for the black
target is 360 millimeters (14 inches) for this setting.
