620 PHOENIX CONTACT
DIN EN 61373 – broadband noise (intensity according to DIN EN 50155)
Vibration test
In transportation technology, terminal
blocks are always exposed to vibrations and
shocks. These occur particularly in the vicinity
of engines, rotating drives, and axles.
For a practical simulation of the vibration
stress, the test objects are subjected to
broadband noise-induced vibrations. This
means that realistic accelerations are
generated at the terminal block and the
connected conductor.
During the category 1b test, the test
objects are exposed to a frequency range of 5
Hz to 150 Hz. The r.m.s. value of the
acceleration is up to 5.72 m/s
2
. The test
objects are tested for 5 hours on each of the
three axes (x, y, z).
In addition to the vibrations, the electrical
contact is monitored during the test to make
it more difficult.
No damage may occur to the terminal
blocks that would impair their further use. In
addition, no contact interruptions > 1 s are
permitted during the test.
All Phoenix Contact terminal blocks,
whatever their connection technology, meet
this high vibration requirement.
IEC 60068-2-27
Shock testing
This test is performed to test and
document the resistance of a terminal
connection to irregular occurring shocks with
varying energy content. Intensities from DIN
EN 50155 and DIN EN 61373 (European
standard for railway applications) are used to
simulate the load in rail traffic.
For the definition of the shock, acceleration
and duration are specified. IEC 60068-2-27
prescribes three positive and negative shocks
on each of the three spatial axes (X, Y, Z). The
simulated accelerations reach 50 m/s
2
with a
shock duration of 30 ms.
No damage may occur at the terminal
connection that would impair further use.
The contact behavior at the test objects is
monitored during the test. When the railway
standard is applied, no contact interruptions
> 1 µs are permitted.
Phoenix Contact terminal blocks achieve
this shock resistance and are suitable for
applications with the most extreme
vibrations.

Vibration test
IEC 60068-2-6
This test demonstrates the vibration
resistance of a terminal connection subjected
to permanent vibrations. Harmonic,
sinusoidal vibrations are applied to the test
object to simulate rotating, pulsating or
oscillating forces. The test is performed on
each of the three spatial axes (X, Y, Z). In the
test, the object runs through a frequency
range of 5 Hz to 150 Hz at a speed of one
octave per minute. The r.m.s. value of the
acceleration is up to 40 m/s
2
. The test objects
are tested for 2 hours on each of the three
axes (x, y, z).
No damage may occur to the terminal
blocks that would impair their further use. In
addition, no contact interruptions > 1 s are
permitted during the test. The contact
resistance is measured before and after the
test.
All connection technologies meet the
requirements of the standard without the
electrical contact being interrupted. They are
therefore particularly suitable for challenging
applications in which the reliable function of
the terminal connection must be ensured,
even when subjected to vibrations.
