Description
• Rugged screw coupling connectors in high
corrosion resistant shells which are made
in nickel aluminum bronze alloy. The design
provides a very high reliability with dry mate
sealing down to 2.000 meters immersion
(deeper depth with special backshells). The M
marine connector series is approved by
VERITAS and LLOYD’S Register of shipping.

M Series
The M Series offer two versions :
•
Single watertightness for cables with single jacket
•
Double watertightness for cables with inner and outer sheaths

• The M Series Single watertightness connectors are available in 5
standard sizes, 9M, 10M, 14M, 20M and 24M. 100 % watertightness
is achieved by both o’rings and packing washers inside the metal
housings. The packing washers offer waterproofing independently of
the cable clamps so that a brutal traction on the cable cannot reduce
the watertightness.
• Since the watertightness is not achieved through overmolding or heat
vulcanization the assembling of connectors can be made outside
workshop on the spot when necessary.
• The main parts achieving watertightness can be seen on fig. 1.
- O’rings (1) are located on receptacles (2), plugs (3) and pin and
socket inserts (4) and (5).
- The packing washer (6) is compressed by metal washers (7) through
screwing of the rear tightening metal sleeve (8).
- The neoprene boot is intended to limit the cable radius curvature.

• The M Series double watertightness connectors are available in
3 sizes 14M, 20M and 24M. The watertightness is ensured at two
levels :
- on the outer jacket
- on the inner sheath.
Mechanical cable strength is provided by :
- a mechanical capture of the braid armor
- a clamping thanks to a metal clamping sleeve on sheath in the event
there is no amour.
• The main parts achieving watertightness at the level of the plug can
be seen on fig. 2.
- On the outer jacket, packing washer (6) are compressed by metal
tightening sleeve (8).
- On the inner sheath, compound injection inside a compounding
housing (10) ensures a second watertightness level (watertightness
relay).
- The neoprene boot (9) has the same roles as preceding version.
Note :
The two versions are compatible with in the following standard
M series shells :
• RER receptacle with round flange, front fitting and rear axial
nut
• REC receptacle with square flange, front fitting with 4 screws
• TER bulkhead with round flange, front fitting and rear axial
nut
• TEC bulkhead with square flange
