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.
