Osisense XU - Reliability data of the XUE1AA2NM12 and XUE5AA2NM12 laser sensors : MTTF & MTTFd

XUE1AA2NM12 : Laser distance sensor with reflector, 0.2 - 30 m, DC supply, analogue output 4...20mA + 2 PNP outputs, IR/red
XUE5AA2NM12 : Laser distance sensor, 0,2 to 6 m, DC supply, analogue output 4...20mA + 2 PNP outputs, IR/red

The reliability data of the XUE1AA2NM12 and XUE5AA2NM12 laser sensors, are the following :
- MTTF = 147 years (mean time to failure),
- MTTFd = 294 years (mean time to dangerous failure),
- DC = 0 (diagnostic coverage) of the sensor alone,
- mission time = 20 years.
They are used for the functional safety, according to the ISO 13849-1 standard (Performance Level).
The MTTF calculation is made according to the IEC 62380 standard, with air ambient temperature of 30°C.
