CMK644 8 Circuit Electrical Connector for Advanced Multi-Wire Applications
TheJINH CMK644 is an 8 circuit electrical connector developed for electrical projects that require multiple conductors, flexible installation methods, and reliable connection performance.
As the largest circuit model in the JINH CMK64 series, CMK644 integrates eight independent connection circuits into one compact connector structure. It combines pluggable connection technology and lever-operated wiring, providing installers with a convenient solution for equipment assembly, electrical installation, and maintenance.
Compared with traditional terminal blocks that require multiple separate components, CMK644 allows several wires to be organized within a single connector. This helps improve wiring efficiency, reduce installation complexity, and create a cleaner electrical layout.
The product is suitable for electrical contractors, control cabinet manufacturers, automation equipment suppliers, lighting manufacturers, and industrial system integrators.
Eight Circuit Design for High-Density Wiring
The key feature of CMK644 is its 8 circuit connection structure.
Many modern electrical systems contain multiple connection points within limited installation space. Using individual connectors for each circuit may increase component quantity and make wiring management more difficult.
CMK644 provides eight independent connection positions in one compact housing.
This design helps users:
- Connect multiple conductors in one location
- Reduce the number of individual terminal components
- Improve wiring organization
- Save installation space
- Simplify circuit maintenance
- Support modular electrical designs
For different connection requirements, the CMK64 series also includes:
CMK642
→ 4 Circuit Pluggable Wire Connector
CMK643
→ 6 Circuit Lever Wire Connector
CMK644
→ 8 Circuit Electrical Connector
Customers can select the suitable circuit capacity according to their project requirements.
Pluggable Connection and Lever Wiring Function
CMK644 combines two practical connection methods:
Pluggable Electrical Connection
The pluggable design allows the connector to be easily installed, removed, and replaced.
This structure is suitable for applications where equipment modules need to be assembled, transported, inspected, or maintained.
Typical applications include:
- Modular electrical systems
- Control equipment
- Automation machinery
- Industrial assemblies
The detachable connection method provides greater flexibility compared with permanent wiring solutions.
Lever Operated Wire Connection
CMK644 also features a lever-operated wiring mechanism.
The orange operating levers allow users to quickly complete wire installation.
The operation process is simple:
- Open the lever
- Insert the conductor
- Close the lever
- Complete the connection
Compared with traditional screw terminal blocks, the lever structure reduces installation steps and improves wiring efficiency.
It also allows individual circuits to be operated separately, making inspection and maintenance more convenient.
Reliable Material Construction
CMK644 uses carefully selected materials for different components to provide stable electrical connection performance.
The main materials include:
- Polycarbonate PC housing
- Polyamide PA66 levers
- Tinned copper conductive parts
- AISI 301 stainless steel contact springs
Polycarbonate PC Housing
The connector shell is made from Polycarbonate PC.
PC material provides good mechanical strength and helps protect internal electrical components.
The compact housing design allows eight circuits to be integrated into one connector while maintaining practical installation dimensions.
Polyamide PA66 Operating Levers
The operating levers are manufactured from Polyamide PA66.
PA66 provides good mechanical performance and supports repeated operation during installation and maintenance.
The lever structure allows installers to easily control each connection point.
Tinned Copper Conductive Components
The internal conductive parts are made from tinned copper.
Copper provides efficient electrical conductivity, while tin plating helps improve corrosion resistance.
The conductive structure works together with the contact springs to maintain stable electrical connections.
AISI 301 Stainless Steel Contact Springs
The contact springs use AISI 301 stainless steel.
The spring mechanism provides continuous pressure between the conductor and conductive parts.
This helps maintain reliable contact performance during long-term operation.
Wide Wire Compatibility
CMK644 supports both flexible and rigid conductors.
Technical specifications:
- Flexible wire:
0.2–1.5mm² - Rigid wire:
0.2–2.5mm² - Rated voltage:
450V AC - Rated current:
24A - Working temperature:
-40℃ to 105℃ - Strip length:
11mm / 0.43 inch
The wide wire compatibility makes CMK644 suitable for different electrical installation environments.
Applications of CMK644
Lighting Systems
CMK644 can be used in LED lighting, commercial lighting, and building electrical projects.
