MX120G™ Sealed
Wire-to-Wire and
Wire-to-Board
Connectors,
Sealed MX120G™ connectors offer greater cost
and space savings while providing superior design
and mating features to meet the needs of harsh
environment, non-automotive transportation
applications
IP67-rated
36783 Male Header,
Through Hole,
Molex’s MX120G™ connector system is a highly compact, sealed wire-
to-wire and wire-to-board family of interconnects with IP67-ratings that
delivers optimal performance especially in wet, high-vibration and wide
operating- temperature conditions.
Right Angle
36799 Wire-to-Wire Female
Crimped Terminal
Designed for rugged, harsh-environment non-automotive applications
that range from tractors and combines to snow mobiles and jet skis;
the MX120G interconnect system can be extended to exterior lighting
applications that include traffic and overhead street lights; and is a more
reliable and less expensive solution to pre-crimped wire-seal alternatives.
36792 Wire-to-Wire Female
Receptacle with
Matte Seal, Seal Cap
and Interface Seal
The MX120G™ wire-to-wire and wire-to-board receptacles feature a single-
piece pre-assembly comprising a high-temperature connector housing,
male silicone seal and a seal cap for strain relief – all pre-assembled and
ready for easy crimp insertion. Standard through-hole male headers have a
3.20mm pitch footprint that makes ample room for PCB traces to support 7
to 10.5 Amp of current over a range of FLRY-B* wire sizes.
36804 Cavity Plug for
Female Receptacle
The connector’s built-in positive locking feature ensures robust terminal
retention while preventing any accidental terminal backout. Its unique twist-
lock design ensures proper terminal alignment of the header contacts with
those of the female receptacle thus eliminating the need for any fasteners.
Female cavity plugs are available to allow selective sealing of circuit voids
in female receptacles for both wire-to-wire and wire-to-board applications.
The terminals of the MX120G receptacle accept FLRY-B* wire sizes of 0.35 to
1 sq. mm conductor diameter allowing the receptacle to take multiple cable
configurations for added flexibility.
MX120G™ Sealed Wire-
to-Wire and Wire-to-
Board Connectors
Color codes on each component of the Wire-to-Board assembly make
identification very easy.

Features and Benefits
Reduced 3.20mm (mating) pitch design offers significant space reduction for the same circuit density offered by
some other makes
Meets IP67 ratings with wide operating temperature range of -40 to +105°Celsius; provides complete protection
of connector against dust and water (up to 1 m depth) and other defined conditions of pressure and time
High-vibration resistance up to 10G acceleration secures mating in high-vibration environment and applications
Independent terminal lock on through hole, right angle male header provides reinforced terminal retention to
receptacle housing to prevent accidental terminal back-out
Twist-lock feature on the terminal and connector prevents rotation of terminal once inserted into the connector
and ensures correct alignment of male terminals with receptacle contacts when mated; eliminating the need for
additional fasteners
Single-piece construction of the female receptacle comprising a pre-assembled connector housing with matte
silicone seal and seal-cap provides greater applied labor and process costsavings
Silicone seals are more durable and able to withstand higher temperatures than ordinary Nitrile-rubber seals
Seal-cap provides strain relief for the seal interface; enables easy insertion of crimped wires directly into the
connector
Mounted male header with self-guiding slot for easy assembly into the ECU (Engine Control Unit) box facilitates
easy assembly and subsequent potting (a process of filling a complete electronic assembly with thermosetting
plastics for protection against shock and vibration as well as for exclusion of moisture and corrosive agents)
