Model 2SBR1 receiver is used with the SBE emitter, which is the same emitter used with the 1 millisecond 3- &
4-wire receiver model SBR1. The response time, however, is determined by the receiver, and is 10 milliseconds.
This pair will work reliably in slightly dirty (average manufacturing plant) conditions up to 60 feet opposed, and
outdoors up to 20 feet. When more distance (or excess gain) is required, use 3- & 4-wire receiver model SBRX1
with the SBEX emitter. The 2SBR1 will not work with the visible emitter SBEV. Use opposed mode sensors as
a first choice in any application, except where the material to be sensed is translucent to light or so small that it
will not break the effective beam diameter. The SBE emiter uses a 3 & 4 wire power block. Powerblocks for use
with SBE include models PBA-1, PBB-1, PBD-1, PBT-1, and PBT48-1 (see pages 16 and 19 for information on
these powerblocks).

Model 2SBL1 is the retroreflective mode scanner block in the 2-wire MULTI-BEAM family. It has the same
excellent optical performance as model SBL1 in the 3- & 4-wire family. If the application calls for breaking a
retroreflective beam with shiny objects such as metal cans or cellophane-wrapped packages, mount the 2SBL1
and its retroreflector at an angle of 10 degrees or more to the shiny surface to eliminate any direct reflections from
the object itself, or consider using 3- & 4-wire scanner block model SBLVAG1 (page 8). Alternatively, the MAXI-
BEAM, VALU-BEAM, and MINI-BEAM families offer 2-wire ac visible and polarized retroreflective models.
Notice from the excess gain curve that the gain falls off at very close sensing ranges, so much so that retroreflectors
cannot be used reliably closer than one inch from the sensor.
2SBC1
Focus at: 1.5inches
These convergent mode 2-wire scanner blocks are identical in performance to their 3- & 4-wire equivalents,
except for the 10 millisecond response time. They are designed for 2-wire applications where background objects
might be seen by proximity mode sensors, or where the precision of a small focused image is important (e.g.- edge-
guiding or position control). Model 2SBC1 provides much more excess gain at its focus point as compared to the
diffuse mode sensors. Convergent mode sensors are preferable to diffuse mode sensors if the distance from the
sensor to the object to be detected can be kept constant. Models 2SBC1 and 2SBC1-4 may be derived from retro
model 2SBL1 by exchange of the upper cover assembly. Model 2SBC1 uses upper cover UC-C, and model
2SBC1-4 uses upper cover model UC-C4. These may be interchanged. A 6-inch convergent model may be created
from either model by substituting upper cover UC-C6. See the Upper Cover Interchangeability Chart in the
Banner product catalog for more information.
