Overview

Banner Optical Touch Buttons (OTB) 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 (depending upon model) is activated

when 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 a black polysulfone (or red polycarbonate) upper

housing and fiber-reinforced thermoplastic polyester base. Polycarbonate models have the letter "L" in their model number suffix.

Environmental considerations for use of the two types differ (see Specifications). The 30 mm threaded base on all models provides easy

mounting, and Banner Optical Touch Buttons are easily retrofitted to existing machines.

Rugged polypropylene (TP) field covers are installed on all models to avoid inadvertent switch actuation due to objects (such as loose

clothing or debris) that might accidentally block the sensing beam and to protect the device. The polypropylene material is capable of

absorbing high impact (even at low temperatures) and is highly resistant to abrasion and to damage by most chemicals.

NOTE: A field cover is installed on this OPTO-TOUCH. If this cover is missing or has become lost or damaged, contact

Banner Engineering immediately for a replacement.

Installing the OTBs

Install the OPTO-TOUCH Optical Touch Buttons so the environment does not adversely affect the means of actuation. Severe contamination

of the touch area (yoke) of the switch or other environmental influences may cause slow response or false energized (on) conditions.

Mount the buttons to protect them from accidental or unintentional operation.

When installing the hand controls, consider ergonomic principles to avoid unnecessary fatigue. Install the touch buttons at a height and in a

location that will be comfortable for the user. See ANSI B11.TR1

Ergonomic Guidelines, and EN894 Safety of Machinery-Ergonomic

Requirements-Control Actuators for more information.

Mount the buttons a safe distance from moving machine parts, as determined by the appropriate standard (for example, ANSI B11.19, ISO

13851). It must not be possible for the operator or other non-qualified persons to relocate them. Failure to establish and maintain the required

distance may result in an increased risk of harm.

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 safeguarding devices and/or related safety controls must be installed and maintained to meet all

appropriate OSHA regulations, ANSI B11 machine safety standards (for example, ANSI B11.19) or other relevant regulations.

CAUTION: Hand Controls—The environment in which hand controls are installed must not adversely affect the means 

of actuation. Severe contamination or other environmental influences may cause slow response or false energized (on)

conditions of mechanical or ergonomic buttons. This may result in exposure to a hazard.
