Introduction

The TOF/Spot-S is a compact yet powerful single-spot
measuring system with the widest range of application
possibilities. It uses Time-of-Flight technology (TOF) to
ensure ultra reliable detection and exact detection range
setting, regardless of the background. This enables a
detection range of up to 6 m (20 ft).
The sensor can measure the exact distance at which
a person or object enters the detection area or it
can simply switch the output at a predefined level.
This means the potential application areas are: From
safeguarding the closing door edges of revolving
doors, to safegarding hinge edges of swing doors, to
safegarding of bus doors. Its small dimensions mean the
TOF/Spot-S is ideal as a built-in solution.

Intended use

The TOF/Spot-S can be used as a safety device which fulfills
the safety levels up to SIL 1 according to EN 61508:2010
and the category 2 (cat. 2) / performance level c (PL c)
according to EN ISO 13849-1:2015. In addition, the sensor
fulfills the standard UL 508-2018 if it connected to a
cat. 2 power supply.
The TOF/Spot-S is intended to safeguard automatic door
application to protect objects and persons according to EN
16005:2013 and DIN 18650:2010. The sensor close the
NO / open the NC switch contacts upon detection of an
object within a pre-defined distance (max. 6 m).
WARNING
System integration
 It is the sole responsibility of the system integrator
to ensure that hazards resulting from the intended
application do not
certification. In addition, it is the sole responsibility of
the system integrator that all relevant stop times and
other binding installation/integration rules stated in
this present manual or in the relevant standards are
followed.

Category 2 operation

There are certain requirements connected to the
certification:
 The system integrator has to define the correct electrical
connection to the controller to fulfill Cat. 2 operation.
 The sensor must be tested regularly by the controller
through the test input.
 For a safety application, the following mounting options
are valid for a category 2 application:
