1) I
e
= max. switching current per contact, U
e
= switching voltage
2) This value applies to cables laid with protection.
The following applies if cables are laid without protection and more than one door must be opened
frequently or if cables are laid without protection and more than 5 doors are connected in series:
Performance Level = PL c, PFH

.
On this topic, also see EN ISO 14119:2014, section 8.6, and ISO TR 24119.
Evaluation of the diagnostic coverage according to ISO TR 24119 must result in at least the value
low
in order to achieve PL d.

3) Old conductor coloring in brackets.
4) There must be no ferromagnetic material in the vicinity of the read head or the actuator.
All data refer to the frontal approach direction and a center offset of m = 0.
5) The minimum operating distances S
omin
between read head and actuator are 1 mm. If the distances
are less than this, the evaluation unit changes to the fault state.
