NOTE: Models with 30-foot attached cable are available (contact factory
for information). 2- and 3-conductor 50- and 100-foot extension cables
(without connectors) are also available. For 2-conductor (emitter) cable:
order model EC12E-50 (50') or model EC12E-100 (100'). For 3-conductor
(receiver) cable: order model EC12R-50 (50') or model EC12R-100 (100').

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 applications 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 frequen-
cies, 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 data sheet 03570 for 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 apertures to create very
narrow, very powerful effective beams (see page 2).
A 1/2" clearance hole is required for mounting. Alternatively, the Banner
model SMB12MM mounting bracket may be used (page 2). SP12 Series
sensors are supplied with 6-1/2 feet of PVC-covered attached cable, or
with 4-pin eurofast™ QD fittings. Options for models with attached cable
are summarized below. See page 4 for QD models. The maximum
recommended emitter or receiver cable length is 100 feet (each). See
pages 2 and 3 for wiring and hookup information.
