CMK202 2 Circuit Push-in Wire Connector for Compact Electrical Wiring
TheJINH CMK202 is a compact 2 circuit push-in wire connector developed for electrical installations where convenient wiring and efficient use of installation space are important.
As part of the JINH CMK20 series, CMK202 provides two connection circuits in a small housing. The design is intended for applications where several wires need to be connected in an organized manner without using a large terminal assembly.
The connector uses a pluggable connection structure, giving installers more flexibility when assembling electrical components and equipment.
CMK202 is suitable for lighting systems, electrical equipment, control applications, appliances, junction box wiring, and general low-voltage electrical installations.
With a rated voltage of 450V and rated current of 24A, the connector provides a practical solution for many everyday electrical connection requirements.
Compact 2 Circuit Configuration
The CMK202 features 2 independent connection circuits.
For electrical installations with only a small number of conductors, using a large multi-position terminal block may take up unnecessary space.
The two-circuit design of CMK202 provides a more compact alternative.
Its small structure can help installers arrange connection points more efficiently, especially inside electrical boxes, lighting equipment, control devices, and compact electrical assemblies.
The two-circuit configuration can be useful for:
- Lighting wiring
- Electrical equipment
- Junction box connections
- Appliance wiring
- Control circuits
- Building electrical installations
- Equipment assembly
By keeping two connection points together, CMK202 can help make wiring layouts easier to understand and maintain.
Push-in Connection for Faster Wiring
CMK202 is designed around a push-in connection concept, providing a straightforward way to install the supported conductor.
Instead of relying on traditional screw tightening, the conductor can be positioned into the connection area according to the product's installation requirements.
This can help reduce repetitive wiring operations during assembly.
For electricians and equipment manufacturers, a simple connection method can be useful when a large number of electrical components need to be installed within a limited period.
CMK202 is particularly suitable for applications where installation speed and compact wiring are both important.
Pluggable Connection for Flexible Installation
Another useful feature of the CMK20 series is its pluggable connection structure.
The pluggable design allows compatible connection components to be assembled and separated more conveniently during equipment installation or maintenance.
This can be useful when electrical equipment needs to be:
- Assembled
- Tested
- Adjusted
- Rewired
- Inspected
- Maintained
For equipment manufacturers, a pluggable structure can also make production assembly more organized.
Instead of treating every wire as an independent connection point, compatible connector components can be arranged as part of a more structured wiring system.
Designed for Rigid Wires
According to the CMK20 series specifications, CMK202 supports:
Rigid wire: 0.5–2.5mm²
This wire range covers a variety of common electrical wiring requirements.
The recommended strip length is:
11mm / 0.43 inch
Correct preparation of the conductor and following the recommended stripping length are important for achieving the intended connection performance.
When selecting CMK202 for a project, the conductor type and cross-sectional area should always be checked against the complete electrical system requirements.
450V Rated Voltage and 24A Rated Current
CMK202 has a rated voltage of:
450V
and a rated current of:
24A
These electrical ratings allow the connector to be considered for various electrical wiring applications.
The actual suitability of a connector depends on the complete installation, including conductor size, ambient temperature, load characteristics, enclosure conditions, installation method, and applicable electrical standards.
For this reason, users should evaluate CMK202 according to the requirements of the specific project.
Transparent Polycarbonate Housing
The connector shell of CMK202 is made from transparent polycarbonate.
The transparent housing gives users a clear view of the internal connection area.
This can be useful during installation because the conductor position can be checked visually.
It can also make inspection more convenient during equipment maintenance.
Polycarbonate is widely used in electrical components because it offers useful mechanical properties and dimensional stability.
The transparent appearance also gives the connector a clean and easily recognizable structure.
Tinned Copper Conductive Parts
The conductive parts of CMK202 are made from tinned copper.
Copper is commonly selected for electrical connection components because of its good electrical conductivity.
The tin-plated surface provides an additional protective layer over the copper conductive component.
Inside the connector, the conductive parts work together with the contact springs to establish the electrical path between the connected conductors.
This material combination is suitable for electrical connection applications where practical conductivity and stable contact are required.
AISI 301 Stainless Steel Contact Springs
The internal contact springs use AISI 301 stainless steel.
The contact springs are an important part of the connection structure because they provide the contact force needed to maintain the conductor connection.
AISI 301 stainless steel is commonly used in spring components because of its mechanical properties and spring characteristics.
The springs work together with the conductive parts and connector housing to form the internal connection system.
Working Temperature from -40°C to 85°C
CMK202 has a specified working temperature range of:
-40°C to 85°C
This range allows the connector to be considered for different indoor and equipment wiring environments.
However, the actual operating environment should always be evaluated according to the complete product design.
Factors such as ambient temperature, electrical load, enclosure conditions, conductor selection, and installation location should be considered before final product selection.
Applications of CMK202
Lighting Systems
CMK202 can be used in various lighting applications where compact electrical connections are required.
It can be considered for:
- LED lighting
- Indoor lighting
- Commercial lighting
