## Overview 

Banner MAXI-BEAM[®] sensors are highly versatile, self-contained, modularized photoelectric sensing controls that are ideally suited to industrial environments. The fixed-field MAXI-BEAM is an ON/OFF switch consisting of three modules (sensor head, power block, and wiring base). A unique, patented, rotatable programming ring enables you to program your choice of light or dark operate mode. The sensing beam has a wavelength of 880 nanometers (infrared). 

Interchangeable MAXI-BEAM[®] sensor heads are rotatable in 90-degree increments around the vertical axis and are also available in retroreflective, diffuse, opposed, convergent, and fiberoptic sensing modes. 

Each MAXI-BEAM sensor head requires a compatible power block and a wiring base. The power block interfaces the sensor head to the circuit to be controlled. Sensor head models RSBFF50 and RSBFF100 may be used only with the MAXIBEAM power blocks (see Power Block Modules for RSBFF Series Sensor Heads (p. 4)). The plug-in design of the model RWB4 wiring base enables easy exchange of the entire sensing electronics without disturbing field wiring. 

RSBFF sensor heads have a convenient dual-purpose top-mounted red LED indicator that lights whenever an object is detected in the fixed sensing field. Also, this LED flashes whenever the sensor's excess gain in the light condition drops below 1.5x. 

MAXI-BEAM sensors are ruggedly constructed of molded PBT to conform to NEMA standards 1, 3, 4, 12, and 13, and have replaceable molded acrylic lenses. Sensor head, power block, and wiring base simply snap and bolt together, with no interwiring necessary. Module interfaces are o-ring and quad-ring sealed for the ultimate in dust, dirt, and moisture resistance. The operating temperature range is –40 °C to +70 °C (–40 °F to +158 °F). 

Note: RSBFF sensor heads may not be used with 2-wire ac power blocks, and are not for use with MAXI-BEAM logic modules.

## Fixed-Field Sensing – Theory of Operation 

The MAXI-BEAM fixed-field sensor head 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 2 (p. 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.

MAXI-BEAM[®] Fixed-field Sensor Heads 

The cutoff distance for the MAXI-BEAM is fixed at 50 mm (2 in, RSBFF50 models) or 100 mm (4 in, RSBFF100 models). 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 (p. 2)).

Figure 3. Fixed-Field Sensing Axis 

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 3 (p. 2). The sensing axis becomes important in certain situations, such as those illustrated in Figure 6 (p. 3) and Figure 7 (p. 3). 

## Background Reflectivity and Placement 

Avoid mirror-like backgrounds that produce specular reflections. A false sensor response occurs 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 4 (p. 2)). Correct this problem by using a diffusely reflective (matte) background, or angling either the sensor or the background (in any plane) so the background does not reflect light back to the sensor (Figure 5 (p. 2)). 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 6 (p. 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. Correct the problem by rotating the sensor 90° (Figure 7 (p. 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.

## Sensing Reliability 

The excess gain curve shows excess gain vs. sensing distance for MAXI-BEAM[®] fixed-field sensors with 50- and 100-millimeter cutoffs. See Performance Curves (p. 5). Maximum excess gain for the 50-millimeter models occurs at a lens-to-object distance of about 15 millimeters. Maximum excess gain for the 100-millimeter models occurs at a lens-to-object distance of about 25 millimeters. Sensing at or near these distances makes maximum use of each sensor's available sensing power. 

Background surfaces and objects must always be placed beyond cutoff distance, if it desired that they be ignored. 

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

The effects of object reflectivity on cutoff distance, though small, may be important for some applications. Sensing of objects of less than 90% reflectivity causes the cutoff distances to be pulled very slightly closer to the sensor. For example, an excess gain of 1 for an object that reflects 1/5 as much light as the 90% white card is represented by the heavy horizontal graph line at excess gain = 5. An object of this reflectivity results in far limit cutoffs of approximately 47 and 90 millimeters (for 50- and 100-mm cutoff units, respectively). 

Objects with reflectivity greater than 90% return more light to the sensor. For this reason, highly reflective backgrounds or background objects such as mirrors, polished metal, and other sources of specular reflections require special consideration. If it is necessary to use a highly reflective background, it should be placed as far beyond the cutoff distance as possible and angled to direct reflected light away from the sensor (see Background Reflectivity and Placement (p. 2)). 

## Program Light/Dark Operate 

Light-/dark-operate selection is done at the programming ring. In light-operate mode, the sensor's normally open output conducts when the sensor sees light. In dark-operate mode, the normally open output conducts when the sensor sees dark. 

1. Loosen the four bolts that hold the sensor head to the power block. 

2. Remove and separate the sensor head and programming ring. 

3. Rejoin the programming ring to the sensor head so that one of the four programming notches on the programming ring aligns with the 10 ms indication beneath the desired operating mode, either DARK OPERATE or LIGHT OPERATE, on the sensor head label. 

4. Reattach the sensor head with programming ring to the power block to lock it in any one of the four 90-degree directions around the sensor's vertical axis. 

## Specifications 

Note: Every RSBFF50 or RSBFF100 sensor head requires a MAXI-BEAM power block and a model RWB4 wiring base (see below). RSBFF sensor heads do not use MAXI-AMP logic modules.
