Machine safety<br />
Safety products level<br />
Functional safety and manufacturer<br />
reliability data of electromechanical<br />
components according to EN/ISO<br />
13849-1 and EN/IEC 62061<br />
Electromechanical components<br />
The following values apply to high or continuous demand mode of operations used<br />
in machinery applications.<br />
The B10 d<br />
value is given to a lifetime of 20 years, but is mainly limited by mechanical<br />
or contact wear.<br />
