WARNING: Not To Be Used for Personnel

Protecon

Never use this device as a sensing device for personnel protecon. 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 applicaons. A sensor failure

or malfuncon can cause either an energized or de-energized sensor output condion.

Adjustable Field Sensing – Theory of Operaon

The receiver element of an adjustable eld sensor produces two currents: I1 and I2. The rao 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 cuto distance relates directly to this rao, which can be

adjusted using the sensor’s mul-turn potenometer.

The cuto distance for model QM42..AFV150 sensors is adjustable from 50 to 150 mm (2 to 6 in) Objects lying beyond the cuto distance are usually

ignored, even if they are highly reecve. However, under certain condions, 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.

Placement

An object beyond the cuto distance, either staonary (and when posioned as shown in Figure 3 on page 2), or moving past the face of the sensor in

a direcon perpendicular to the sensing axis, may cause unwanted triggering of the sensor if more light is reected to the near detector than to the far

detector. Correct the problem by rotang the sensor 90° (Figure 4 on page 2). The object then reects the R1 and R2 elds equally, resulng in no

false triggering. A beer soluon, if possible, may be to reposion the object or the sensor.
