INTERNATIONAL PROTECTION CLASSES
PRINCIPLE OF WATERTIGHTNESS
WITH ODU MINIꢂSNAP®
Acc. IEC 60529:2013 (VDE 0470-1:2014).
ODU makes both IP 50 and IP 68 in the L and B series in the same diameter. For reasons of compatibility with
the competition, ODU now offers the series K as well, which has a greater diameter than the non-watertight
model ꢀ series Lꢁ.

All IP 68 submersible ODU MINI-SNAP connectors
have a rated water depth of 2 m ꢀ 0.2 barꢁ for 24
hours in accordance with IEC 60529:2013 ꢀ VDE
0470-1:2014ꢁ. A watertight connector requires a
sealing in a cable collet system.
The sleeve must fit over the cable precisely. The
cable jacket must be smooth, cylindrical and free
of grooves. The connector should be encapsulated
to make it watertight when not mated.

1 The following applies to the contacts: the contacts are protected in cases 1, 2 and 3 when mated. When not mated, the contacts are only
protected by a protective cover ꢀ see page 69 for series L, page 110 for series K and page 148 for series Bꢁ which must be removed before
mating. 2 The cable seal with elastic disks requires coordination with the cable. Decisive factors: Diameter tolerance, roundness,
cable structure, cable jacket hardness.
