APPLICATION NOTE: as a general rule
regarding background objects in diffuse sens-
ing, verify that the distance to the nearest
background object is at least three times the
distance from the sensor to the object to be
sensed. For example, if a product passes one
inch from an SBD1 sensor, the nearest back-
ground object should be at least three inches
further away.
MULTI-BEAM
DIFFUSE Mode
Sensing Mode
OBJECT
SBD1
Range: 12 inches (30cm)
Response: 1ms on/off
Repeatability: 0.3ms
Beam: infrared, 940nm
SBDL1
Range: 24 inches (60cm)
Response: 1ms on/off
Repeatability: 0.3ms
Beam: infrared, 940nm
SBDX1: first choice for diffuse (proximity) mode applications when there is no requirement for less than 10 ms
response and where there are no background objects to falsely return light. High excess gain for reliable detection
of most materials with low reflectivity which pass within 10 inches (25cm) of the sensor.
SBDX1MD: wide beam angle for forgiving alignment to reflective objects. First choice for detection of clear or
translucent glass or plastics. High excess gain at close range, with fast fall-off of gain near the maximum sensing
distance for optical suppression of reflective background. This model may be created from model SBDX1 by
substituting upper cover (lens) model UC-DMB.
SBDX1MD
Range: 24 inches (60cm)
Response: 10ms on/off
Repeatability: 1.5ms
Beam: infrared, 880nm
SBD1: short range diffuse mode sensor with relatively wide field of view. Loses gain rapidly near the end of its
range. As a result, its response to background objects is suppressed. However, use caution when applying any
diffuse mode sensor if background reflectivity exceeds the reflectivity of the object to be sensed.
SBDL1: longer range than SBD1, but with less response to objects passing the sensor at close range, and greater
sensitivity to background objects. Models SBD1 and SBDL1 are identical except for their upper cover (lens)
assembly (SBD1 uses UC-D; SBDL1 uses UC-L; see Upper Cover Chart in the Banner product catalog).
SBDX1
Range: 6 feet (2m)
Response: 10ms on/off
Repeatability: 1.5ms
Beam: infrared, 880nm
