Banner optotouch photoelectric ergonomic finger switch
This is a Banner Optotouch photoelectric finger switch
Supply Voltage: 20 to 30V ac or dc (25 milliamps, maximum).

* Ergonomically designed photoelectric touch buttons provide a superior substitute or replacement for mechanical push buttons
* Choose from OTB Series (momentary action) or LTB Series (latching output)
* AC models have electromechanical relay output; dc models have solid-state switch
* Use OTB types with DUO-TOUCH AT-xM-2A module for two-hand control
* All models are supplied with a black field cover designed to prevent inadvertent switch activation; red, yellow or green field covers are available as an option
OTBVR81 Series Optical Touch Buttons are touch-activated photoelectric
switches designed to replace capacitive touch switches and mechanical

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
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.

external threads and 1/2" NPSM internal threads. Base requires a 1-

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
will cause embrittlement of the polysulfone cover. Window glass
effectively filters longer wavelength ultraviolet and provides excellent
protection from sunlight. Where protection from direct sunlight
is not possible, consider special-order models with Lexan

OPTO-TOUCHs should be cleaned periodically
cleaner, or a mild soap solution and a soft cloth.
as they will attack polysulfone to varying degrees: esters,
ketones, aromatic hydrocarbons, and chlorinated hydrocarbons.
