Technical content

Sensing cutoff point is adjustable from 125 mm to 400 mm (5 in to 16 in)

  • 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 1 of sensing field cutoff point from 125 mm to 400 mm; no mechanical adjustments to worry about
  • Low-cost, compact, rugged 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 WARNING: Not To Be Used for Personnel Protection Never use this device as a sensing device for personnel protection. Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.

The ratio of these two currents changes as the received light signal moves along the length of the receiver element. See Figure 1 on page 2. The sensing cutoff distance relates directly to this ratio, which can be adjusted using the sensor’s multi-turn potentiometer. the cutoff distance are usually ignored, even if they are highly reflective. However, under certain conditions, it is possible to falsely detect a background object (see Placement on page 2). As a general rule, the most reliable sensing of an object which approaches from the side occurs when the line of approach is parallel to the sensing axis.

As an example, the cutoff point decreases 10% for a 6% reflectance black target when the cutoff point is 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). -10 +10 75 mm(1 in) 150 mm(2 in) 225 mm(3 in) 300 mm(4 in) Cutoff Point Variation Relative to 90% Reflectance White Test Card PercentDeviation 375 mm(5 in) 450 mm(6 in) 18% Gray Color Sensitivity 6 % Black Color Sensitivity QMT42 Series 400 mm Adjustable Field Sensors P/N 49211 Rev.
