STB Series Self-Checking Optical Touch Buttons
STB Series Self-Checking Touch Buttons were designed primarily to provide the self-
checking function required in control-reliable machine cycle initiation applications.
However, STBs are suitable for use anywhere mechanical push buttons or the original
OTB Touch Buttons are being used today.
Both the solid-state and relay-output versions have complementary outputs and can be
connected to switch power to equipment as long as the STB’s switching voltage and
current limits are not exceeded (see output ratings, page 8).
STBs must be connected to a type IIIC Two-Hand-Control circuit module, in most
cases, when used to initiate potentially dangerous machine cycles.
Mechanical Installation
OSHA and ANSI require that the hand controls be mounted to protect them from acci-
dental or unintentional operation. Use shields, covers, rings, collars, dividers, or similar
protection to prevent accidental switch actuation and to discourage use of forearms or
elbows. European standard EN 574 includes a detailed discussion of approaches to
protection of hand controls.
The hand controls must be arranged to require the use of both hands for simultaneous
actuation. They must be located far enough apart so that the operator cannot operate
both hand controls by the use of one arm.
Figure 2 shows two methods for mounting the STB Touch Buttons. When mounted on
top of the control bar, the protective field covers should be in place, as shown. For added
protection, mount the STB Touch Buttons sideways under and behind a protective hood,
rather than on top of the bar. This side mount prevents the operator from positioning
and leaving an object in the path of the beam, intentionally bypassing the safeguard.

Total protection for the two-hand-control
system from “defeat” is not possible.
However, the user is required by OSHA
regulations to arrange and protect hand
controls to minimize possibility of defeat or
accidental actuation.
STB Series Touch Buttons are Self-Checking
ergonomic actuating devices, but are not, by
themselves, safety devices. To be used in a
safety application, the STB must be
interfaced with a type IIIC two-hand-control
module, such as the Banner AT-FM-10K, in
order to meet all relevant safety
requirements of the appropriate standards.
