 Dirt on the surface does not reduce the switching distance
 Precise door guides are not required In some systems, the read head and evaluation unit form a sealed unit.
In this case the term safety switch is used, as all safety functions are
integrated into one component (see section on safety switches further

The system then consists of the components:

Evaluation units
The read head is connected to a special CES evaluation unit. This unit
checks the actuator's bit pattern. The data transmission from the read
head to the evaluation unit is dynamic and single-channel. All potential
faults (e.g. broken cable, short circuit, failure of the actuator) are reliably
detected. The number of read heads that can be connected depends on
the evaluation unit.
The evaluation units have enable paths with which e. g. relays or contac-
tors can be switched. If the evaluation unit detects a valid actuator, the
evaluation unit closes its enable paths.
How the evaluation is performed in detail depends on whether the evalu-
ation unit is a unicode or multicode evaluation unit.

Safety switches
On the safety switches, read head and evaluation unit are integrated into
one housing. Their principle of operation does not differ from other CES
systems. The safety switches are also available in unicode, multicode and
fixcode versions. The advantage compared to evaluation with a separate
evaluation unit is in the combination of the complete switch function in
one compact housing. This feature makes possible decentral evaluation
