Features
"S2" Series EZ-BEAM sensors are designed to connect directly to a "smart" BUS
system network junction, such as the Banner BUS-DEPOT
® . S2 Series sensors are
internally wired to take advantage of the EZ-BEAM's marginal signal ALARM output.
The ALARM output is normally open (N.O.) and conducts whenever the sensor's
excess gain drops to between 1X and 1.5X in the light condition. The sensing signal
output is also normally open, which means that the output conducts when light is
sensed (i.e. - light operate).
In order to take advantage of the second ALARM output, S2 sensors require the use
of BUS DEPOT junctions which offer two channels per input. Both sensor outputs are
PNP (current sourcing) for direct connection to a BUS network junction using
standard 4-pin euro-style extension cables.
S2 Series sensors offer all of the features and powerful sensing performance that EZ-
BEAMs offer. The innovative dual-indicator system takes the guesswork out of sensor
performance monitoring. Housings are tightly sealed and the sensor circuitry is
epoxy-encapsulated for reliable duty in wet or oily sensing environments. Models are
available for opposed (through-beam), polarized retroreflective and fixed-field diffuse
sensing (see chart on page 2, for available ranges).
As the chart on page 2 shows, there are three basic housing styles. The "S" style is a
threaded barrel which is available in 18 mm or 30 mm diameters. The "Q" style offers
either 25 mm or 40 mm right-angle rectangular housings. Finally, the "T" style is a
patented
† right-angle design available with either an 18 mm or 30 mm threaded lens.
The "T" style combines the mounting ease of a barrel sensor with the low-profile
advantage of a right-angle design.
Several mounting options are offered, including angled brackets and split-clamp
brackets. S2 series sensors may also be simply mounted through suitable clearance
holes. See page 7 for more information.
