Dimension drawing
Safety precautions
To ensure safety, both safety outputs (LA and LB) must always be evaluated.
Typical operating distance (for safety actuator and position actuator)
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.

Notes on the electrical connection
Changing the approach direction
The active face of the read head can be adjusted
in 5 directions. The face is marked with the
EUCHNER logo. The center of the circle
corresponds to the middle of the read head.

The data outputs D0, D1, D2, D3 have no
safety function.
Both safety outputs LA and LB must be
evaluated.
The safety outputs LA and LB as well as the
data outputs D0, D1, D2, D3 are short
circuit-proof.
All the electrical connections must either be
isolated from the mains supply by a safety
transformer according to IEC/EN 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. contac-
tors) connected to the power supply must
be connected to appropriate interference
suppression units.
