SOURIAU on the railway market
The SOURIAU solution offers a wide range
of connector layouts providing a simplified
process from purchasing to harnessing:
1 type of contact to order, to manage,
to stock, to crimp for a wide range of
connectors.
SOURIAU’s standardisation policy is the
best compromise between technology and
cost.
SOURIAU connectors ensure the continuity
of the network with railway qualified
connectors integrating new technologies:
copper contacts, Quadrax and fibre optics
to transfer high speed Ethernet and other
data protocols.
SOURIAU, along with its customers is
committed to the research of energy
efficiency and sustainability.
The use of lightweight materials, fiber optics
and high contact density contribute to the
weight reduction of train equipments and
help railway operators to save energy.

Rated insulation voltage U
Nm
* according to EN 50-1
24-1:
"Railway applications - Insulation coordination".
The rated insulation voltage U
Nm
* is given per layout
according to:
• overvoltage level:
- OV3 means a 2500V rated impulse voltage
U
Nm
* is not the working voltage.
U
Nm
* has to be chosen according to the voltage of the
power supply U
n
.
*Definition of U
Nm
rated insulation voltage (EN 50-1
24-1): r.m.s. withstand voltage value
assigned by the manufacturer to the equipment or to a part of it, characterizing the specified
(long-term) withstand capability of its insulation. NOTE: The rated insulation voltage is not
necessarily equal to the-rated voltage of equipment which is primarily related to functional
performance.
• pollution degree of the environment:
- PD2 means only non conductive pollution occurs except that
occasionally a temporary conductivity caused by condensation is
to be expected
- PD3 means conductive pollution occurs or dry non conductive
pollution occurs which becomes conductive due to condensation
which is to be expected

• creepage and clearance, depending on the insert
and the type of the contacts used:
for layouts that use AWG16 contacts we recommend to use shorter
female contacts (RC16M23GE7K) to reach a higher operating
voltage level.
