max. temperature +90 °C

test to DIN IEC 60068-2-14, Nb
Vibration (random)
in operation, with temperature change

6 g eff. (10 Hz...2,000 Hz)

test to DIN EN 60068-2-64
Vibration was tested with standard
sockets for PCB mounting.

Behaviour at vibrations depends on
design, quality and age (number of
push-in cycles) of the socket particularly
regarding duration of the vibration and
the mounting position
