TOF/Spot

4. Introduction

The TOF/Spot 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 immense: from
safeguarding the closing door edges of revolving doors,
to optimizing warehouse door opening times, to providing
touchless button functionality. Its small dimensions mean
the TOF/Spot is ideal as a built-in solution.

Category 2 operation (TOF/Spot-S)

The TOF/Spot-S is certified by TÜV according to
EN 13849-1, Cat. 2, PLC ; EN 16005; DIN 18650 and
SIL 1 according to EN 61508.
However, there are certain requirements connected to this
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:
