OPTO-TOUCH™
Momentary Action Optical Touch Buttons
OTB Series
Banner Optical Touch Buttons are touch-activated photoelectric switches
designed to replace capacitive touch switches and mechanical push buttons.
The OPTO-TOUCH's SPDT electromechanical relay or solid-state output (de-
pendinguponmodel)isactivatedforaslongasafinger, introducedintothe"touch
area" (yoke) of the switch, interrupts the OPTO-TOUCH's infrared sensing beam.
OTB Series Momentary Action
Optical Touch Button (QD model shown)
Banner Optical Touch Buttons are ergonomically designed to eliminate the hand,
wrist, and arm stresses associated with mechanical push buttons. They require
absolutely no physical pressure to operate. LED indicators light for "power on"
and "output activated".
AllmodelsarehighlyresistanttoEMI, RFI, andambientlightinterference. OTBs
haveeitherablackpolysulfone(orredLexan®)upperhousingandVALOX® base.
Lexan® models have the letter "L" in their model number suffix. Environmental
considerations for use of the two types differ; see specifications below. The 30-
mm threaded base on all models provides easy mounting, and Banner Optical
Touch Buttons are easily retrofitted to existing machines. See pages 2 and 5 for
model listings.

Specifications
Supply Voltage: Models for 105 to 130V ac, 210 to 250V ac (50/60 M30 x 1,5 external threads and 1/2" NPSM internal threads. Base
Hz), 10 to 30V dc, or 20 to 30V ac/dc (at 25 mA, exclusive of load).
requiresa1-3/16"diametermountinghole(fitsmoststandardautomo-
tive-size "jumbo" legend plates and oiltight pushbutton holes). Sup-
plied with a field cover of polycarbonate-PET polyester. OPTO-
TOUCH OTBs are rated NEMA 1, 3, 4, 4X, 12, and 13.
Output Configuration:
AC and ac/dc models: All models have SPDT electromechanical relay
(one N.O. contact, one N.C. contact).
Cable: DC-only Quick-disconnect (QD) modelsrequire model MBCC-
412 4-conductor mini-type cable (p/n 25226); AC and ac/dc Quick-
disconnect (QD) models require MBCC-512 5-conductor cable (p/n
25496; cables are purchased separately). Mini-type QD cables are 12 feet
long. Models with attached cable (non-QD models) are supplied with 6
feet of PVC-jacketed, 22 AWG 4- or 5-conductor cable.
DC-only models:
OTBVN6 models have complementary NPN sinking outputs;
OTBVP6 models have complementary PNP sourcing outputs.
Output Rating:
AC and ac/dc models: Maximum voltage is 250V ac or 30V dc.
Maximum current is 7 amps (resistive load), 1 HP max.
Minimum load is .05 watts (dc), .05VA (ac).
Environmental Considerations (models with polysulfone housing):
Prolonged exposure of the OPTO-TOUCH to direct outdoor sunlight
will cause embrittlement of the polysulfone housing. Window glass
effectively filters longer wavelength ultraviolet and provides excel-
lent protection from sunlight. Contact the factory Application Engi-
neering Department regarding outdoor applications.
Mechanical life of relay is 50,000,000 operations (minimum).
Electrical life of relay is 100,000 operations (min.) at full resistive load.
Transient suppression recommended when switching inductive loads.
DC models: 150 mA maximum load (each output).
Ambient Light Immunity: 120,000 lux (direct sunlight).
Environmental Considerations (models with Lexan® housing):
Prolonged exposure of the OPTO-TOUCH to hot water and moist
high-temperature environments above 150°F (66°C) should be
avoided. Aromatic hydrocarbons (such as xylene and toluene),
halogenated hydrocarbons, and strong alkalis should be avoided.
Clean periodically using mild soap solution and a soft cloth. Avoid
strong alkaline materials.
EMI/RFI Immunity: The OPTO-TOUCH is highly resistant to
both single and mixed EMI and RFI noise sources.
Operating Temperature Range: -20 to +50°C (-4 to +122°F).
Indicator LEDs: Two indicator LEDs. One lights whenever power
is "on"; the other lights whenever the output relay is activated.
Construction: Black polysulfone (or red Lexan®) upper housing
and fiber-reinforced VALOX® base. Electronics fully epoxy-encap-
sulated. Totally sealed, non-metallic enclosure. Threaded base has
Read all WARNINGs carefully.
WARNING. Banner OPTO-TOUCH™ OTB and OTBL Series Optical Touch Buttons are intended
asgeneral-purpose initiators, and are not safety devices. Like most solid-state devices, they are as equally
likely to fail in the conducting ("on") state as in the non-conducting ("off") state. If OPTO-TOUCH Optical
Touch Buttons are used to initiate machines or operations in which false operation of an Optical Touch Button could be
dangerous, point-of-operation guarding devices or related safety controls must be installed and maintained to meet all
appropriate OSHA regulations and ANSI B11 machine safety standards.
