Banner LTB OPTO-TOUCH Optical Touch Buttons - Manual

Banner LTB Series Optical Touch Buttons are touch-activated photoelec-
tric switches designed to replace capacitive touch switches and mechani-
cal push buttons. The OPTO-TOUCH's SPDT electromechanical relay
output changes state, alternating between "on" and "off", whenever a finger,
introduced into the "touch area" (yoke) of the switch, interrupts the LTB's
infrared sensing beam.
Banner LTBs are ergonomically designed to eliminate the hand, wrist, and
arm stresses associated with mechanical push buttons. They require abso-
lutely no physical pressure to operate. LED indicators light for "power on"
and "output activated".
LTBs are highly resistant to EMI, RFI, and ambient light interference, and are
constructed from black polysulfone (or red Lexan
® ) and VALOX ® for reliabil-
ity in industrial environments. The 30-mm threaded base provides easy
mounting, and LTBs are easily retrofitted to existing machines. See the
listings on pages 2 and 3 for available models.

WARNING.
Banner OPTO-TOUCH™ LTB 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.
NOTE: In addition to the standards and regulations mentioned above, there are numerous regulations and machine safety
standards that apply to specific industries. For assistance in obtaining copies of any of these standards, contact Banner at
the address and or numbers listed at the bottom of page 4.
Supply Voltage: 105 to 130V ac or 210 to 250V ac, depending upon
model. See listings of available models, pages 2 and 3.
Output Configuration: All models have SPDT electromechanical
relay (one N.O. contact, one N.C. contact).
Output Rating: Maximum voltage is 250V ac or 30V dc.
Maximum current 7 amps (resistive load), 1 HP max.
Minimum load .05 watts (dc), .05VA (ac).
Mechanical life of relay 50,000,000 operations (min.).
Electrical life of relay 100,000 operations (min.) at full resistive load.
Transient suppression is recommended when switching inductive loads.
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: T wo indicator LEDs. One lights when power is
"on"; the other lights when the infrared sensing beam is interrupted.
Construction:
Black polysulfone or red Lexan ® upper housing and fiber-reinforced
VALOX ® base. Electronics fully epoxy-encapsulated. Totally sealed,
non-metallic enclosure. The LTB's threaded base has M30 x 1,5
external threads and 1/2" NPSM internal threads. The base requires
a 1-3/16" diameter mounting hole (fits most standard automotive-size
"jumbo" legend plates and oiltight pushbutton holes). OPTO-TOUCH
LTBs are rated NEMA 1, 3, 4, 4X, 12, and 13.
Specifications
Alternate Action Optical Touch Buttons
Cable: Quick-disconnect (QD) models require model MBCC-512
5-conductor mini-type cable (p/n 25496), purchased separately. QD
cables are 12 feet long. Models with attached cable (non-QD models)
are supplied with 6 feet of PVC-jacketed, 22 AWG 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. Clean periodi-
cally using a mild soap solution and a soft cloth. Avoid the following
substances, as they will attack polysulfone to varying degrees: esters,
ketones, aromatic hydrocarbons, chlorinated hydrocarbons, and strong
alkaline materials.
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.
