OTB Series
OPTO-TOUCH ™
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-
pending upon model) is activated for as long as a finger, introduced into the "touch
area" (yoke) of the switch, interrupts the OPTO-TOUCH's infrared sensing beam.
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".
All models are highly resistant to EMI, RFI, and ambient light interference. OTBs
have either a black polysulfone (or red Lexan
® ) upper housing and VALOX ® 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.

OTB Series Momentary Action
Optical Touch Button (QD model shown)
WARNING.
Banner OPTO-TOUCH™ OTB and OTBL Series Optical Touch Buttons are intended
as general-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.
M30 x 1,5 external threads and 1/2" NPSM internal threads. Base
requires a 1-3/16" diameter mounting hole (fits most standard automo-
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.
Cable: DC-only Quick-disconnect (QD) models require 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.
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.
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.
Momentary Action Optical Touch Buttons
Supply Voltage: Models for 105 to 130V ac, 210 to 250V ac (50/60
Hz), 10 to 30V dc, or 20 to 30V ac/dc (at 25 mA, exclusive of load).
Output Configuration:
AC and ac/dc models: All models have SPDT electromechanical relay
(one N.O. contact, one N.C. contact).
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).
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).
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
