CMK665 5 Circuit High Current Connector for Multi-Wire Electrical Applications
TheJINH CMK665 is a 5 circuit high current connector developed for electrical applications where multiple conductors need to be connected in an organized and practical way.
As the largest circuit configuration in the JINH CMK66 series, CMK665 provides five independent connection circuits within one compact connector. It combines a pluggable connection structure with lever-operated wiring, giving installers more flexibility during electrical installation, equipment assembly, inspection, and maintenance.
With a rated voltage of 600V and rated current of 41A, CMK665 is designed for electrical applications that require a higher current capacity than many compact wiring connectors.
The product supports both flexible and rigid conductors and can be used in lighting systems, electrical equipment, control cabinets, automation machinery, industrial wiring, and equipment manufacturing.
Five Circuit Design for Multi-Wire Connections
The main feature of CMK665 is its 5 circuit connection configuration.
Electrical equipment often contains several individual circuits that need to be connected within a limited installation area. Using a separate connector for each circuit can increase component quantity and make internal wiring more difficult to organize.
CMK665 integrates five connection circuits into one connector.
This configuration can help:
- Manage multiple conductors in one location
- Reduce the number of separate connection components
- Keep internal wiring more organized
- Make equipment assembly easier
- Simplify future maintenance
- Make better use of installation space
The five-circuit design makes CMK665 suitable for applications where a compact connector needs to handle several electrical connections at the same time.
High Current Capacity for Electrical Equipment
CMK665 is designed with a rated current of:
41A
and a rated voltage of:
600V
The combination of a multi-circuit structure and higher electrical rating makes CMK665 suitable for a range of electrical equipment and wiring applications.
The actual electrical performance of any installation depends on factors such as conductor size, ambient temperature, load conditions, installation method, and applicable electrical standards.
Therefore, users should select the connector according to the complete system requirements.
Pluggable Connection for Flexible Installation
CMK665 supports a pluggable connection structure.
The detachable design allows the connection section to be installed and removed when necessary.
This can be particularly useful for equipment that requires:
- Modular assembly
- Routine inspection
- Wiring adjustment
- Component replacement
- Equipment maintenance
During manufacturing, the pluggable structure can make electrical modules easier to assemble.
During maintenance, it can also make the connection system easier to access.
This provides more flexibility than a purely fixed wiring arrangement.
Lever Wiring for Convenient Operation
CMK665 also uses a lever-operated wiring mechanism.
The orange operating levers provide a simple way to control the individual connection points.
A typical wiring process is straightforward:
- Open the corresponding lever.
- Insert the prepared conductor.
- Close the lever.
- Check the connection.
This mechanism reduces the need for repeated screw tightening and can make wiring work more convenient.
It is useful for electricians and equipment technicians during:
- Electrical installation
- Equipment assembly
- Circuit adjustment
- Routine inspection
- Wire replacement
- Maintenance work
The individual lever structure also allows the required circuit to be operated separately.
Supports Flexible and Rigid Wires
CMK665 is designed to accommodate both flexible and rigid conductors.
The specified wire ranges are:
Flexible wire: 0.2–4mm²
Rigid wire: 0.2–6mm²
This makes the connector suitable for different wiring configurations.
The recommended strip length is:
11mm / 0.43 inch
Using the recommended stripping length can help ensure that the conductor is correctly positioned inside the connection area.
Transparent Polycarbonate Housing
The housing of CMK665 is made from transparent polycarbonate.
One practical advantage of the transparent housing is that users can see the internal connection area more easily.
During installation, the transparent shell can help installers check conductor positioning.
It can also make visual inspection more convenient during maintenance.
Polycarbonate is widely used for electrical component housings because it offers useful mechanical properties and dimensional stability.
The transparent appearance also gives CMK665 a clean and easy-to-identify structure.
Polyamide Operating Levers
The operating levers are made from Polyamide.
The orange levers are clearly visible and provide a convenient operating point for each connection circuit.
The lever structure is designed for repeated operation during installation and maintenance.
For applications involving multiple connectors or dense wiring, clearly visible operating levers can make it easier for technicians to locate and operate the required connection point.
Tinned Copper Conductive Parts
CMK665 uses tinned copper conductive parts for its internal electrical connection path.
Copper is widely used in electrical connectors because of its good electrical conductivity.
The tin-plated surface can provide additional protection for the conductive parts against oxidation.
The conductive components work together with the contact springs to establish the electrical connection between the inserted conductors.
This material combination is suitable for electrical connection products that require practical conductivity and stable contact performance.
AISI 301 Stainless Steel Contact Springs
The internal contact springs are made from AISI 301 stainless steel.
The contact spring provides the pressure required to maintain contact between the conductor and conductive component.
AISI 301 stainless steel is commonly used in spring applications because of its mechanical strength and spring characteristics.
The spring works together with the lever mechanism and conductive parts to form the complete connection structure.
Wide Working Temperature Range
CMK665 is specified for a working temperature range of:
-40°C to 105°C
This allows the connector to be considered for various electrical equipment and installation environments.
When selecting CMK665 for a specific project, users should also consider ambient conditions, electrical load, enclosure design, conductor type, and installation requirements.
Applications of CMK665
Lighting Systems
CMK665 can be used for LED lighting, commercial lighting, building lighting, and other electrical lighting systems.
The five-circuit structure allows several lighting connections to be organized in one connector.
Control Panels
Control panels often contain multiple electrical circuits within a relatively limited space.
CMK665 can help organize several connection points while maintaining a compact wiring layout.
Electrical Equipment
Equipment manufacturers can use CMK665 for internal wiring where several conductors need to be connected through one component.
The pluggable structure can also make equipment assembly and maintenance more convenient.
Automation Machinery
Automation equipment contains different electrical modules, control circuits, and wiring points.
CMK665 can be used for internal equipment connections and modular wiring applications.
Industrial Wiring
The600V / 41A rating makes CMK665 suitable for consideration in various industrial electrical applications.
The actual application should be evaluated according to the electrical requirements of the complete system.
Equipment Manufacturing
The combination of five circuits, lever operation, and pluggable connection makes CMK665 suitable for equipment manufacturers looking for a practical wiring component.
It can be integrated into electrical equipment during production and accessed later for inspection or maintenance.
