Sealed MX120G™ connectors offer greater cost and space savings while providing superior design and mating features to meet the needs of harshenvironment, non-automotive transportation applications Molex’s MX120G™ connector system is a highly compact, sealed wireto-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. 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. The MX120G™ wire-to-wire and wire-to-board receptacles feature a singlepiece 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. MX120G™ Sealed Wire-to-Wire and Wire-to-Board Connectors, IP67-rated 36783 Male Header, Through Hole, Right Angle 36799 Wire-to-Wire Female Crimped Terminal 36792 Wire-to-Wire Female Receptacle with Matte Seal, Seal Cap and Interface Seal 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 twistlock 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. Color codes on each component of the Wire-to-Board assembly make identification very easy.
