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-

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

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)

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.

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.

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.

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.

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.
