Connectors Series M – Installation and Maintenance Instructions
Description
4. Description
Connectors of the M series are universal industry con-
nectors and oer high reliability.
M1 and M3 connectors are dust-proof and water pres-
sure tight (protection class IP67 when mated and IP69K
when not mated with screwed on protection cap).
Moreover, they are largely resistant to acids and alka-
lines as well as to heat and cold.
There is a large application range. Typical applications
are systems and components where reliability under
dicult circumstances is important, e.g. in mining,
shipbuilding, power plant construction, mechanical
and trac engineering, environmental technology or
in food processing.
Connectors of the M series have a modular design
which oers a wide range of applications.
4.1 Features
Common features of M1 and M3 series connectors:
X
Modular design: Customized and cost-eective
realisation of your application.
X
Shells: Various kinds of assembly, e.g. plug and re-
ceptacle shells with and without strain relief, with
ange, for use with heat shrink boots or backshells
with thread and cable gland, also ange-mount
angled receptacle. Materials used:
- Fibre glass reinforced polyamide: impact resist-
ant
- Non-halogen, UL listed
X
Design exibility: Plug and receptacle shell can
be tted with either pin or socket insert, i.e. fully
insulated socket inserts can be mounted on the
live part.
X
Orientation: Pin and socket inserts can be located
in the shell in two dierent positions, thus pre-
venting mismating. It also allows for the unmistak-
able connection of for example two connectors
with dierent voltages to one and the same piece
of equipment.
X
Contacts:
- High-quality screw machine contacts
- Silver or gold plated
- Crimp connection depending on series and
contact arrangement from 0.5 … 6 mm².
Special features of M1 series:
X
Number of contacts: 4 and 6 + PE
X
5.000 mating cycles at constant low contact resist-
ance
X
Current rating:16 A max
Special features of M3 series:
X
Number of contacts: 6 + PE, 5+3 + PE, 12 +PE and
7+7 + PE
X
5.000 mating cycles at constant low contact resist-
ance
X
Current rating: 50 A max
