ching current!
Functional safety
Reliability, test according to IEC 61508 by using SN 29500
MTTF (mean time to failure): 239 [years]
PFD (probability of failure on demand): 5.212*10-4
These specifications depend on the ambient condi-
tions as well as on the operating conditions of the
sensor.
Note, that a proof test interval of T1 = 1 year is
given. The MTTF value corresponds to the MTBF
value, because the sensor is a non-repairable device.
