Overview
STB Self-Checking Optical Touch Buttons are touch-activated photoelectric devices designed to replace capacitive touch
switches and mechanical push buttons. Their outputs activate while a finger is in the “touch area” (yoke) of the switch,
interrupting the button’s infrared sensing beam.
Banner STB Series 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 when power is on
and outputs are activated.
All models are immune to EMI, RFI, and ambient light interference. STBs have a black polyetherimide upper housing and
yellow PBT base. The 30 mm threaded base on all models provides easy mounting and easy retrofitting into existing
applications. Rugged yellow polypropylene (TP) field covers are supplied with all models to prevent inadvertent switch
actuation due to objects (such as loose clothing or debris) which might accidentally block the sensing beam. 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.

WARNING: Point-of-Operation Guarding
When properly installed, a two-hand control
device provides protection only for the hands of
the machine operator. It may be necessary to
install additional safeguarding, such as safety
light screens, additional two-hand controls, and/or
hard guards, to protect all individuals from
hazardous machinery.
Failure to properly guard hazardous
machinery can result in a dangerous
condition which could lead to serious injury
or death.
STB Self-Checking Optical Touch Buttons are very similar to the proven and popular OTB Series buttons. The dual-
microcontroller internal design of the new buttons, however, allows the hookup to a Banner DUO-TOUCH SG Two-Hand-
Control Safety Module, or other two-hand-control designed to meet Type IIIC requirements per ISO 13851 (EN 574)
(requiring 1 normally open and 1 normally closed contact per input channel). These microcontrollers perform a continuous
self-check. The emitter is continuously pulsed, and receiver response is checked accordingly by the microcontrollers. STB
Series Touch Buttons are designed to immediately detect any internal component failure, go into a lockout mode, and
indicate the failure with a flashing green Fault LED.
