Fixed-Field Mode Overview

T30 Series self-contained fixed-field sensors are small, powerful, infrared diffuse mode sensors with far-limit cutoff (a type of background
suppression). Their high excess gain and fixed-field technology allow detection of objects of low reflectivity, while ignoring background
surfaces. The cutoff distance is fixed. Backgrounds and background objects must always be placed beyond the cutoff distance.

Fixed-Field Sensing – Theory of Operation

The T30FF compares the reflections of its emitted light beam (E) from an object back to the sensor’s two differently aimed detectors, R1
and R2. See Figure 1. Fixed-Field Concept on page 2. If the near detector's (R1) light signal is stronger than the far detector's (R2)
light signal (see object A in the Figure below, closer than the cutoff distance), the sensor responds to the object. If the far detector's (R2)
light signal is stronger than the near detector's (R1) light signal (see object B in the Figure below, beyond the cutoff distance), the sensor
ignores the object.

Standard 2 m (6.5 ft) cable models are listed. To order 9 m (30 ft) cable: add suffix W/30 (for example, T306EW/30). To order 4-pin Euro-style QD models: add suffix Q (for example,
T306EQ). A model with a QD connector requires a mating cable; see Cables on page 7.

T30 Sensors - DC-Voltage Series

The cutoff distance for model T30 Series sensors is fixed at 200, 400 or 600 millimeters (7.9 in, 16.7 in, or 23.6 in). Objects lying beyond
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 Background Reflectivity and Placement on page 2).

Figure 2. Fixed-Field Sensing Axis

Figure 1. Fixed-Field Concept

In the drawings and information provided in this document, the letters E, R1, and R2 identify how the sensor’s three optical elements
(Emitter “E”, Near Detector “R1”, and Far Detector “R2”) line up across the face of the sensor. The location of these elements defines the
sensing axis, see Figure 2. Fixed-Field Sensing Axis on page 2. The sensing axis becomes important in certain situations, such as those
illustrated in Figure 5. Object Beyond Cutoff - Problem on page 3 and Figure 6. Object Beyond Cutoff - Solution on page 3.

Sensor Setup

Sensing Reliability

For highest sensitivity, position the target object for sensing at or near the point of maximum excess gain. See Performance Curves on
page 5 for the excess gain curves for these sensors. Maximum excess gain for all models occurs at a lens-to-object distance of about
40 mm (1.5 in). Sensing at or near this distance makes the maximum use of each sensor’s available sensing power. The background
must be placed beyond the cutoff distance. Note that the reflectivity of the background surface also may affect the cutoff distance. Follow­ing these guidelines will improve sensing reliability.

Background Reflectivity and Placement

Avoid mirror-like backgrounds that produce specular reflections. False sensor response will occur if a background surface reflects the
sensor’s light more to the near detector (R1) than to the far detector (R2). The result is a false ON condition (Figure 3. Reflective Back-

ground - Problem on page 3). To cure this problem, use a diffusely reflective (matte) background, or angle either the sensor or the

background (in any plane) so the background does not reflect light back to the sensor (Figure 4. Reflective Background - Solution on
page 3). Position the background as far beyond the cutoff distance as possible.

An object beyond the cutoff distance, either stationary (and when positioned as shown in Figure 5. Object Beyond Cutoff - Problem on
page 3), or moving past the face of the sensor in a direction perpendicular to the sensing axis, may cause unwanted triggering of the
sensor if more light is reflected to the near detector than to the far detector. The problem is easily remedied by rotating the sensor 90°
(Figure 6. Object Beyond Cutoff - Solution on page 3). The object then reflects the R1 and R2 fields equally, resulting in no false
triggering. A better solution, if possible, may be to reposition the object or the sensor.

Color Sensitivity

The effects of object reflectivity on cutoff distance, though small, may be important for some applications. It is expected that at any given
cutoff setting, the actual cutoff distance for lower reflectance targets is slightly shorter than for higher reflectance targets. This behavior is
known as color sensitivity.

For example, an excess gain of 1 (see Performance Curves on page 5) for an object that reflects 1/10 as much light as the 90% white
card is represented by the horizontal graph line at excess gain = 10. An object of this reflectivity results in a far limit cutoff of approximate­ly 190 mm (7.5 in) for the 200 mm (8 in) cutoff model, for example; thus 190 mm represents the cutoff for this sensor and target.

These excess gain curves were generated using a white test card of 90% reflectance. Objects with reflectivity of less than 90% reflect
less light back to the sensor, and thus require proportionately more excess gain in order to be sensed with the same reliability as more
reflective objects. When sensing an object of very low reflectivity, it may be especially important to sense it at or near the distance of
maximum excess gain.
