M Series
JUPITER
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, 9 M, 10 M, 14 M, 20 M and 24 M. 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.
Double Watertightness on inner and outer sheaths
 FDED straight plug
 PCDE cable connecting plug
 The M Series double watertightness connectors are available in 3
sizes 14 M, 20 M and 24 M . 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 amor.
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

Single Watertightness on outer sheath :
 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 compouding
housing (10) ensures a second watertightness level (watertightness
relay).
- The neoprene boot (9) has the same roles as preceeding version.
