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.
