CMK662 2 Circuit Pluggable Wire Connector for Flexible Electrical Wiring
TheJINH CMK662 is a compact 2 circuit pluggable wire connector developed for electrical installations where convenient wiring, flexible connection, and higher electrical capacity are important.
As part of the JINH CMK66 series, CMK662 combines a pluggable connection structure with lever-operated wiring. This gives installers more flexibility than a conventional fixed terminal connection, especially when equipment needs to be assembled, adjusted, inspected, or serviced.
The two-circuit configuration makes CMK662 suitable for applications that need a compact connection point without using several separate terminals. At the same time, its 600V rated voltage and 41A rated current make it suitable for a wider range of electrical wiring requirements.
CMK662 can be used in lighting systems, electrical equipment, control cabinets, automation equipment, machinery wiring, and other electrical installations where a compact and practical connector is required.
Pluggable Connection for Easier Installation
A major feature of CMK662 is its pluggable connection design.
Instead of relying only on permanent wiring, the connector can be used as a detachable connection point. This can be useful during equipment assembly, installation, maintenance, or component replacement.
For equipment manufacturers, a pluggable structure can make wiring modules easier to handle during production. For installers, it can simplify connection and disconnection when equipment needs to be checked or serviced.
The design is particularly useful for applications where electrical components may need to be removed or replaced during the service life of the equipment.
Lever Operation Simplifies Wire Connection
CMK662 also features an easy-to-operate lever wiring mechanism.
The orange operating levers provide a practical way to control the connection points. During installation, the lever can be opened, the conductor inserted into the appropriate position, and the lever closed to secure the wire.
This operating method avoids repeated screw tightening and can make routine wiring work more straightforward.
It can be useful when electricians need to:
- Install several wires
- Adjust existing wiring
- Inspect connection points
- Replace conductors
- Carry out equipment maintenance
Because the connection points can be operated individually, installers can work on the required circuit without unnecessarily disturbing other wiring.
2 Circuit Compact Connection Design
CMK662 provides 2 independent circuits in one compact connector.
A two-circuit configuration is useful for applications where only a limited number of wires need to be connected but a detachable and easy-to-operate connector is preferred.
The compact design can help reduce unnecessary wiring components and keep electrical connections organized.
CMK66 series products are available in different circuit configurations. Customers can select according to their project requirements:
- CMK662 – 2 circuits
- CMK663 – 3 circuits
- CMK665 – 5 circuits
This makes the series suitable for different wiring densities without changing the basic connection concept.
600V and 41A Electrical Rating
Compared with some smaller wire connectors, CMK662 is designed for applications requiring a higher electrical rating.
The product is rated at:
Rated Voltage: 600V
Rated Current: 41A
These specifications allow CMK662 to be considered for a broader range of electrical equipment and wiring applications.
The actual suitability of the connector should always be evaluated according to the complete electrical system, conductor type, installation conditions, and applicable standards.
Wide Wire Size Compatibility
Another practical feature of CMK662 is its conductor compatibility.
The connector supports:
Flexible wire: 0.2–4mm²
Rigid wire: 0.2–6mm²
Supporting both flexible and rigid conductors gives installers more freedom when selecting wiring materials for different projects.
The wider conductor range is useful for electrical equipment where different wire sizes may be used within the same product family.
The specified strip length is:
11mm / 0.43 inch
Following the recommended stripping length helps ensure that the conductor is correctly positioned inside the connection area.
Transparent Polycarbonate Housing
The connector shell is made from transparent polycarbonate.
The transparent housing provides a clear view of the internal connection area. This can be useful during installation and inspection because users can visually check the position of the conductors.
Polycarbonate is also commonly used in electrical components where mechanical strength, dimensional stability, and practical enclosure performance are required.
The transparent appearance gives CMK662 a clean and easily identifiable structure, which can be helpful when organizing multiple electrical components inside an equipment enclosure.
Polyamide Operating Levers
The operating levers are made from Polyamide.
The lever is designed for repeated opening and closing during wire installation and maintenance.
Its bright orange appearance also makes the operating mechanism easy to identify when several components are installed close together.
For electricians and equipment technicians, a clearly visible operating lever can make routine connection work easier.
Tinned Copper Conductive Parts
CMK662 uses tinned copper conductive components for its internal electrical connection path.
Copper is widely used for electrical conductors because of its good conductivity. Tin plating on the surface can provide additional protection against oxidation and help maintain the condition of the conductive surface.
The conductive components work together with the internal contact springs to create the electrical connection between the inserted conductors.
AISI 301 Stainless Steel Contact Springs
The contact springs are made from AISI 301 stainless steel.
The spring structure provides the contact force needed to keep the conductor in position.
AISI 301 stainless steel is commonly selected for spring components because of its combination of mechanical strength, spring characteristics, and corrosion resistance.
Together with the conductive parts and lever structure, the contact springs form an important part of the CMK662 connection system.
Working Temperature from -40°C to 105°C
CMK662 is specified for a working temperature range of:
-40°C to 105°C
This broad temperature range makes the connector suitable for a variety of indoor and equipment-based electrical applications.
The actual operating conditions should be considered when selecting a connector for a particular project, including ambient temperature, electrical load, enclosure conditions, and installation environment.
Applications of CMK662
CMK662 can be used across a variety of electrical connection applications.
Lighting Systems
The connector can be used for LED lighting, commercial lighting, building lighting, and other electrical lighting installations.
Its pluggable design can make installation and maintenance more convenient.
Electrical Equipment
Equipment manufacturers can integrate CMK662 into internal wiring systems where multiple wires need to be connected in a compact area.
Control Panels
The two-circuit configuration can be useful in control cabinets and electrical panels where organized wiring is important.
Automation Equipment
Automation systems often contain multiple electrical components and connection points. CMK662 provides a practical option for connecting equipment wiring.
Industrial Wiring
The 600V and 41A rating makes CMK662 suitable for consideration in various industrial electrical applications, subject to the requirements of the complete system.
Equipment Assembly
The pluggable structure can be useful during equipment production and assembly, particularly when wiring modules may need to be installed or removed.
