Notes on the electrical connection
Typical operating distance (only in conjunction with actuator CES-A-BBA)
For a side approach direction for the actuator and safety switch, a minimum distance of s = 3 mm
must be maintained so that the operating distance of the side lobes is not entered.

In combination with actuator CES-A-BBA
The operating voltage U
The contacts LA/LB, -LA/-LB and OUT are short circuit-proof, however they
are not reverse polarity protected
All the electrical connections must either be isolated from the mains supply by
a safety transformer according to EN/IEC 61558 with limited output voltage in
the event of a fault, or by other equivalent isolation measures.
If a common power supply is used, all the inductive and capacitive loads (e.g.
contactors) connected to the power supply must be connected to appropriate
interference suppression units.

Safety precautions
To ensure safety, both safety outputs (LA and
LB) must always be evaluated.
Changing the approach direction
The active face of the read head can be adjus-
ted in 5 directions. The face is marked with the
EUCHNER logo. The center of the circle corres-
ponds to the middle of the read head.
