Banner SP12 Series sensors are a family of powerful, modulated,
totally-encapsulated opposed mode remote sensor pairs in compact,
threaded-barrel type housings. They are the ideal choice for applica-
tions that require high excess gain together with small size in difficult
sensing environments. SP12 Series sensors are especially effective at
penetrating heavy contaminants when used at close range.
The preamplified design of these sensors results in exceptional noise
immunity. Signals carried along remote receiver cables are often
subject to interference (from electrical noise sources) that can be as
strong as (or stronger than) the desired light signal. The severity of this
problem often worsens with increasing sensor cable length. SP12
Series receivers contain a preamplifier that immediately boosts the
received light signal to a high level before sending it down the cable to
the rest of the sensing system.
SP12 Series sensors are designed for use with the Banner CD Series
MAXI-AMP™ modules. CD Series modules provide sensor power,
additional amplification, a choice of several programmable timing
logic functions (CD5 models), and output circuitry for interfacing to
a load. They also allow two different programmable sensor modulation
frequencies, making it possible to use multiple high-powered sensor
pairs in close proximity to each other without optical crosstalk. CD
Series modules are available for a wide range of supply voltages. Each
CD module powers one SP12 emitter/receiver pair. See page 3 for more
information.
SP12 sensors are rated NEMA 6P (IEC IP67) for use in wet locations.
There is a choice of either VALOX
® or stainless steel housing style (see
table, below). Positive sealing at both ends of the sensors, with no
exposed epoxy interfaces, eliminates all leak paths (including capillary
leakage). Electronics are fully encapsulated for maximum resistance to
mechanical shock and vibration. Lenses are acrylic, and quad-ring
sealed. These sensors may be used with watertight, thread-on aper-
tures to create very narrow, very powerful effective beams (see next
page).
A 1/2" clearance hole is required for mounting. Alternatively, the
Banner model SMB12MM mounting bracket may be used (see next
page). SP12 Series sensors are supplied with 6-1/2 feet of PVC-
covered attached cable, or QD connectors (page 8). Options for models
with attached cable are summarized below. The maximum recom-
mended emitter or receiver cable length is 100 feet (each).
