Reliability values according to EN ISO 13849-1

Monitoring of the guard position with 1 read head
Category 4 (This value is dependent on the number of switching cycles and the switching current)
Performance Level PL e (This value is dependent on the number of switching cycles and the switching current)
PFHD 2.5 x 10-8 (This value is dependent on the number of switching cycles and the switching current.)
Monitoring of the guard position with > 1 read head
Category 3 (This value is dependent on the number of switching cycles and the switching current)
Performance Level PL d (This value is dependent on the number of switching cycles and the switching current. 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, PFHd = 1.1E-6. 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.)
