Retroreflective PicoDot
with BRT-51X51BM
PD49 Series Ruggedized PicoDot
Datasheet
• Environmentally sealed housing is only slightly larger than standard PD45
models, with all the functionality. Rated IEC IP67; NEMA 6
• Class 2 laser diode light source
• Convergent beam models have precise, high-energy sensing spot at focus,
available in four focal lengths: 50 mm (2 in), 100 mm (4 in), 200 mm (8 in),
and 300 mm (12 in)
• Retroreflective models have precise, narrow beam; excellent for sensing the
presence of tiny parts at close range, small parts at medium ranges, and for
accurate sensing over long distances
• Fast, 0.2 millisecond sensing response for high-speed sensing or counting
• 10 to 30 V dc operation; choice of NPN or PNP complementary solid state output
• Choose models with 2 m (6.5 ft) or 9 m (30 ft) unterminated cable, or with 150
mm (6 in) Euro-style pigtail quick-disconnect (QD) 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.

Retroreflective-Mode Models
Excellent for applications where high sensing power and small beam size are
important. Operates over sensing ranges typically accomplished only by
conventional opposed-mode photoelectrics; uses a special filter to polarize the
emitted light, filtering out unwanted reflections from shiny objects.
To order 9 m (30 ft) cables, add “W/30” to the model number of any cabled
sensor (e.g., PD49VN6LLP W/30). Models with QD connectors require a mating
cable.

Retroreflective Sensor Alignment
Because the PicoDot laser sensor has such a long sensing range, and because its beam is so narrow (compared to the
beam of typical retro sensors), its alignment is somewhat less forgiving and more difficult to accomplish. As indicated, the
effect of angular misalignment can be dramatic, especially over distance. For example, with one 51 mm (2 in) reflective
target mounted at a distance of 6 m (20 ft) from the sensor, only one degree of angular misalignment will cause the
center of the laser beam to miss the center of the target by 102 mm (4 in), and miss the target altogether by almost 76
mm (3 in).
Alignment tip: When using a small retroreflective target at medium or long range, it is often useful to temporarily attach
(or suspend) a strip of retroreflective tape (such as BRT-THG-2-100) along a line that intersects the real target. The visible
red laser beam is easily seen in normal room lighting; sight along the beam toward the target, from behind the sensor.
Move the sensor to scan the laser beam back and forth across the tape strip, to guide the beam onto the target.
The use of mounting bracket SMB-46A may simplify alignment, because of its precision-positioning feature. After mounting
the bracket and the sensor, tighten the screws in the two corners of the bracket to position the beam in the exact spot
needed.

Retroreflective Sensor Beam Size
Unlike conventional retroreflective sensors, the
retroreflective laser has the ability to sense relatively small
profiles. The figures demonstrate the diameter of the
smallest opaque rod that reliably breaks the laser beam at
several sensor-to-object distances. These values assume an
excess gain of about 10×. Flooding effects are possible
when the gain is much higher (reduce sensor gain in this
situation in order to reliably detect minimum object sizes).
Note the shape of the beam is elliptical and its size
increases as the distance from the sensor increases.
Minimum object detection sizes are dependent on both the
object’s distance from the sensor, and the direction (with
respect to the beam’s X and Y axes) in which the object
crosses the beam.

Installation Notes - Class 2 Laser Safety Notes
Low-power lasers are, by definition, incapable of causing eye injury within the duration
of a blink (aversion response) of 0.25 seconds. They also must emit only visible
wavelengths (400 to 700 nm). Therefore, an ocular hazard may exist only if individuals
overcome their natural aversion to bright light and stare directly into the laser beam.
• Do not stare at the laser.
• Do not point the laser at a person’s eye.
• Mount open laser beam paths either above or below eye level, where practical.
• Terminate the beam emitted by the laser product at the end of its useful path.

CAUTION: Use of controls adjustments or performance of procedures other than those specified herein
may result in hazardous radiation exposure; per EN 60825. Do not attempt to disassemble this sensor
for repair. A defective unit must be returned to the manufacturer.
