M12 Series Metal Barrel Sensors Overview
Power LED
Banner’s M12 family of sensors offers a full complement of sensing modes, all packaged in a compact yet rugged metal housing. Their popular 12-mm threaded barrel design allows them to mount easily into tight spaces, with the excellent performance expected of much larger sensors. The single-turn Gain potentiometer on most models and two Signal LEDs (positioned on either side of the housing for visibility) provide easy alignment and configuration for reliable sensing (see Figure 1). Note that when the signal LED is not ON, the green Power LED is visible through all three LED ports.
Fixed-Field Mode Overview M12 Series fixed-field sensors are powerful diffuse-mode sensors with far-limit cutoff (a type of background suppression). Their high excess gain and fixed-field technology allow them to detect objects of low reflectivity that are directly in front of another surface, while ignoring the surface in the background.

The cutoff distance is fixed. Backgrounds and background objects must always be placed beyond the cutoff distance. Receiver Elements
Fixed-Field Sensing – Theory of Operation In operation, the M12FF 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). If the near detector (R1) light signal is stronger than the far detector (R2) light signal (see object A, closer than the cutoff distance), the sensor responds to the object. If the far detector (R2) light signal is stronger than the near detector (R1) light signal (see object B, object beyond the cutoff distance), the sensor ignores the object. The cutoff distance for model M12FF sensors is fixed at 25, 50, or 75 mm (1", 2", or 3"). Objects lying beyond the cutoff distance are ignored, even if they are highly reflective. However, it is possible to falsely detect a background object, under certain conditions (see Background Reflectivity and Placement).

In the drawings and discussion on these pages, 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). The sensing axis becomes important in certain situations, such as those illustrated in Figures 6 and 7.
Figure 2. Fixed-field concept
Fixed-Field Sensor Setup Sensing Reliability For best sensing reliability, the sensor-to-object distance should be positioned to maximize excess gain. The excess gain curves for these sensors are shown on page 5. Sensing at higher excess gains will make maximum use of the sensor’s available sensing power. The background must be placed beyond the cutoff distance; more reflective backgrounds must be placed further back. Following these two guidelines will improve sensing reliability.

M12 Series Metal Barrel Sensors 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 strongly to the near detector, or “sensing” detector (R1) than to the far detector, or “cutoff” detector (R2). The result is a false ON condition (Figure 4). Use of a diffusely-reflective (matte) background will cure this problem. Other possible solutions are to angle the sensor or angle the background (in any plane) so the background does not reflect light back to the sensor (see Figure 5). 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), or if it moves past the face of the sensor in a direction perpendicular to the sensing axis, can cause unwanted triggering of the sensor if it reflects more light to the near detector than to the far detector. The problem is easily remedied by rotating the sensor 90° (Figure 7). 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 will be slightly shorter than for higher reflectance targets. This behavior is known as color sensitivity. The excess gain curves on page 5 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.

Reflective Background or Moving Object
A reflective background object in this position or moving across the sensor face in this axis will be ignored.
A reflective background object in this position or moving across the sensor face in this axis and direction may cause false sensor response.
