With evaluation unit CES-A-F1B-04B-AS1 in conjunction with read
head CES-A-LNA...AS1 or CES-A-LNA-SC and actuator CES-A-
BBA on surface mounting of the read head and the actuator. If
installed flush, the switching distance changes as a function of
the installation depth and the safety guard material.
For a side approach direction for the actuator and read head,
a minimum distance of s = 3 mm must be maintained so that
the operating distance of the side lobes is not entered.

1) Corresponds to the risk time according to
EN 60947-5-3. This is the maximum switch-off
delay for the safety outputs following removal of
the actuator. In case of EMC interference in excess
of the requirements in accordance with
EN 60947-5-3, the switch-off delay can increase
to max. 750 ms. After a brief actuation < 0.8 s,
the switch-on delay can increase to max. 3 s if
this is followed immediately by further actuation.

installed flush, the switching distance changes as
a function of the installation depth and the safety
