Banner LTB OPTO-TOUCH Optical Touch Buttons - Manual

Banner OTBVR81 Series Optical Touch Buttons are touch-activated photo-
electric switches designed to replace capacitive touch switches and me-
chanical push buttons. The OPTO-TOUCH's SPDT electromechanical relay
is activated for as long as a finger, introduced into the "touch area" (yoke) of
the switch, interrupts the OTB's infrared sensing beam.
Banner OTBs 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".
OTBs are highly resistant to EMI, RFI, and ambient light interference, and are
constructed from black polysulfone and VALOX
® for reliability in industrial
environments. The 30-mm threaded base provides easy mounting, and OTBs
are easily retrofitted to existing machines. See page 2 for available models.

WARNING.
Banner OPTO-TOUCH™ OTB 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.

OTBVR81 Series Momentary Action
Optical Touch Button (QD model shown)
Supply Voltage: 20 to 30V ac or dc (25 milliamps, maximum).
Output Configuration
All models 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 100mA at 24V.
Mechanical life of relay 50,000,000 operations (minimum). Electri-
cal life of relay 100,000 operations (min.) at full resistive load.
Transient suppression is recommended when switching inductive
loads.
Specifications
Dimensions
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 when power is
"on"; the other lights when the infrared sensing beam is interrupted.
Construction: Black polysulfone cover and fiber-reinforced
VALOX ® base. Electronics fully epoxy-encapsulated. Totally sealed,
non-metallic enclosure. The OTB's threaded base has M30 x 1,5
external threads and 1/2" NPSM internal threads. Base requires a 1-
3/16" diameter mounting hole (fits most standard automotive-size
"jumbo" legend plates and oiltight pushbutton holes). OPTO-TOUCH
OTBs are rated NEMA 1, 3, 4, 4X, 12, and 13.
Cable: Quick-disconnect (QD) models require model MBCC-
512 5-conductor cable (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 :
Prolonged exposure of the OPTO-TOUCH to direct outdoor sunlight
will cause embrittlement of the polysulfone cover. Window glass
effectively filters longer wavelength ultraviolet and provides excel-
lent protection from sunlight. Where protection from direct sunlight
is not possible, consider special-order models with Lexan
® covers (see
the other side of this sheet for information).
Cleaning Information:
OPTO-TOUCHs should be cleaned periodically using alcohol, glass
cleaner, or a mild soap solution and a soft cloth. Avoid the following
substances, as they will attack polysulfone to varying degrees: esters,
ketones, aromatic hydrocarbons, and chlorinated hydrocarbons.
