CMK203 3 Circuit Pluggable Wire Connector for Organized Electrical Wiring

TheJINH CMK203 is a 3 circuit pluggable wire connector developed for electrical applications that require multiple connection points in a compact and organized format.

As part of the JINH CMK20 series, CMK203 provides three independent connection circuits within one connector. This configuration is suitable for applications where two circuits are not enough, while a larger multi-circuit terminal may be unnecessary.

CMK203 combines a push-in connection structure with a pluggable design, providing a practical solution for electrical installation, equipment assembly, and maintenance.

The connector is designed for 0.5–2.5mm² rigid wires, with a rated voltage of 450V and rated current of 24A.

Its transparent polycarbonate housing, tinned copper conductive parts, and AISI 301 stainless steel contact springs provide a practical material combination for electrical connection applications.

CMK203 can be used in lighting equipment, electrical appliances, control systems, junction boxes, equipment wiring, and other suitable electrical installations.


Three Circuit Configuration

CMK203 provides:

3 independent circuits

The three-circuit structure allows several electrical connections to be arranged within one connector.

For applications with multiple conductors, using individual connectors for each connection point can increase the number of components and make wiring organization more difficult.

CMK203 brings three connection positions together in one compact component.

This design can help users:

  • Organize multiple connection points
  • Reduce separate connector usage
  • Simplify internal wiring
  • Improve assembly efficiency
  • Make maintenance more convenient
  • Use installation space more effectively

The three-circuit configuration is particularly suitable for electrical equipment where several wires need to be connected within a relatively limited area.


Push-in Connection for Convenient Wiring

CMK203 uses a push-in connection structure designed to simplify conductor installation.

The push-in concept provides an alternative to conventional screw-type wiring methods.

For suitable rigid conductors, the connection process can be completed with fewer manual operations.

This can be useful in production environments where electrical components need to be installed repeatedly.

For electricians and equipment manufacturers, reducing unnecessary wiring steps can help make assembly more efficient.

CMK203 is suitable for applications where convenient installation is an important consideration.


Pluggable Design for Flexible Equipment Assembly

One of the useful features of CMK203 is its pluggable connection structure.

The pluggable design provides additional flexibility when electrical components need to be installed, separated, adjusted, or maintained.

This can be particularly useful in equipment manufacturing.

During production, compatible components can be assembled as part of a structured wiring system.

During maintenance, the connection can be accessed more conveniently when equipment needs inspection or replacement.

Potential applications include:

  • Electrical equipment assembly
  • Lighting equipment installation
  • Control system wiring
  • Equipment maintenance
  • Circuit adjustment
  • Electrical module assembly

The pluggable structure makes CMK203 suitable for projects where wiring flexibility is important.


0.5–2.5mm² Rigid Wire Compatibility

CMK203 is designed for:

0.5–2.5mm² rigid wires

This conductor range covers a variety of common electrical wiring requirements.

The specified strip length is:

11mm / 0.43 inch

Proper conductor preparation is important for achieving the intended connection.

Installers should prepare the wire according to the recommended stripping length and make sure the conductor is correctly positioned inside the connector.

When selecting CMK203, the conductor type and size should be checked against the requirements of the complete electrical installation.


450V Rated Voltage and 24A Rated Current

CMK203 has a rated voltage of:

450V

and a rated current of:

24A

These specifications make the connector suitable for a variety of electrical connection applications.

However, actual application suitability depends on the complete electrical system.

Factors such as conductor size, operating temperature, load conditions, installation method, enclosure design, and applicable electrical standards should be considered when selecting the connector.


Transparent Polycarbonate Housing

The connector shell of CMK203 is made from:

Transparent Polycarbonate

The transparent housing makes the connection area easier to see.

During installation, users can visually check the position of the conductor inside the connector.

This can be helpful when several connectors are installed in the same electrical enclosure.

The transparent housing can also make routine inspection more convenient.

Polycarbonate is widely used in electrical components because of its useful mechanical properties and dimensional stability.


Tinned Copper Conductive Parts

CMK203 uses:

Tinned Copper Conductive Parts

for its internal electrical connection.

Copper is commonly used in electrical connectors because of its good electrical conductivity.

The tin-plated surface adds a protective layer to the copper conductive component.

The conductive parts work together with the contact springs to establish the electrical path between the connected conductors.

This material combination provides a practical solution for electrical connection applications.


AISI 301 Stainless Steel Contact Springs

The internal contact springs of CMK203 are made from:

AISI 301 Stainless Steel

The contact springs provide the contact force required to maintain the conductor connection.

AISI 301 stainless steel is commonly used for spring components because of its mechanical properties and spring characteristics.

The contact springs work together with the conductive parts and connector structure to form the internal connection system.


Working Temperature: -40°C to 85°C

CMK203 has a specified working temperature range of:

-40°C to 85°C

This allows the connector to be considered for a variety of electrical equipment and wiring environments.

For specific applications, users should also evaluate ambient temperature, electrical load, enclosure conditions, conductor specifications, and installation location.

Correct product selection should be based on the complete application requirements.


Applications of CMK203

Lighting Systems

CMK203 can be used for suitable lighting applications where multiple electrical connections need to be organized.

Potential applications include:

  • LED lighting
  • Indoor lighting
  • Commercial lighting
  • Building wiring
  • Lighting equipment

The three-circuit structure can help organize multiple connections in one location.


Electrical Equipment

Electrical equipment often contains several internal wiring points.

CMK203 provides three circuits within one connector, which can help manufacturers organize internal wiring more efficiently.


Junction Boxes

CMK203 can be used in suitable junction box applications where multiple conductors need to be connected within a compact space.

Its pluggable structure can also provide flexibility during equipment installation and maintenance.


Control Systems

The three-circuit configuration can be used for selected control wiring applications.

It can help organize several connection points within control equipment.


Electrical Appliances

CMK203 may be considered for suitable appliance wiring applications when the electrical ratings and installation requirements match the product specifications.


Equipment Manufacturing

The combination of three circuits and a pluggable structure makes CMK203 suitable for equipment manufacturers looking for organized electrical connection solutions.

It can be incorporated into equipment during production and accessed later for inspection or maintenance.
