Jack A2C A2-CZ PCB Control Board 9950014900

The Jack A2C / A2-CZ PCB Control Board 9950014900 works as the main electronic control board for compatible Jack A2 series direct-drive single-needle lockstitch sewing machines. It manages motor speed, needle positioning, automatic thread trimming, pedal response, and communication between the machine’s electronic components.

This PCB works with compatible Jack A2, A2C, A2-CZ, A2-CQ and A2S series machines, subject to the correct board version and connector configuration. The board carries the 9950014900 part reference and provides a replacement solution for compatible Jack A2-series control systems.

महत्वपूर्ण: Check the PCB label, part number, connector arrangement, and machine model before ordering. The A2B and A2C boards belong to different PCB generations and may not interchange directly.

What Does the Jack A2C PCB Control?

The main PCB acts as the electronic control centre of the sewing machine. It coordinates signals between the direct-drive motor, operation panel, foot pedal, needle-position system, sensors, and automatic thread-trimming components.

The control board manages functions such as:

• Direct-drive motor speed
• Needle up/down positioning
• Automatic thread trimming
• Foot pedal response
• Electronic machine functions
• Operation panel communication
• Sensor signals
• Solenoid control

These functions help the sewing machine maintain consistent electronic operation during regular production work.

Jack A2B vs A2C PCB Difference

The Jack A2B and A2C PCBs represent different control-board generations. Both boards perform similar main-control functions, but their circuit layouts, electronic components, firmware configuration, and connector arrangements can differ.

Can You Swap an A2B PCB With an A2C PCB?

Do not assume direct interchangeability. The A2B and A2C boards may use different connector pin configurations, electronic circuits, and control settings.

Before you order a replacement, compare the part number, PCB model label, connector arrangement, and existing board with the replacement PCB.

Please verify the shape, part number, and connector configuration of your existing PCB before purchasing.

प्रमुख विशेषताऐं

Main Electronic Control

The PCB controls the major electronic functions of compatible Jack A2-series direct-drive sewing machines.

Motor Speed Control

The board communicates with the direct-drive motor system and manages sewing speed according to machine inputs.

Needle Positioning

The PCB manages electronic needle-position signals so the machine can stop the needle in the required position.

Automatic Thread Trimming

On compatible machines, the control board coordinates the electronic signals required for the automatic thread-trimming mechanism.

Multi-Connector Interface

The PCB provides multiple electrical connections for components such as the motor, operation panel, foot pedal, sensors, and solenoid systems. Match each connection with the original board before installation.

How To Replace the PCB

1. Switch off the sewing machine and disconnect the power supply.
2. Open the control box according to the machine service procedure.
3. Take a clear photo of the existing cable connections.
4. Compare the old PCB’s part number and connector layout with the replacement.
5. Disconnect the original PCB carefully.
6. Position the replacement PCB correctly.
7. Connect each cable to its matching socket.
8. Secure the control box before reconnecting power.
9. Switch on the machine and check the display and basic functions.
10. Test the motor, needle positioning, and thread trimming where applicable.

If you are unsure about electrical connections, ask a qualified sewing-machine technician to install the PCB.

अक्सर पूछे जाने वाले प्रश्नों

Is this PCB compatible with the Jack A2-CZ sewing machine?

Yes, this PCB matches Jack A2-CZ machines that use the 9950014900 board configuration. Compare the part number, PCB label, and connector arrangement with your existing control board before ordering. Different Jack A2 machine revisions can use different electronic control boards.

What is the part number of this Jack A2C PCB?

This Jack A2C / A2-CZ PCB carries the 9950014900 part reference. Check the number printed on your existing board before purchase because Jack A2-series machines can use different PCB generations and configurations.

Is the Jack A2C PCB the same as the Jack A2B PCB?

नहीं।. The A2C and A2B boards use different PCB generations. The supplied references are 9950014900 for A2C/A2-CZ और 19510031200 for A2B. Compare the board label, connectors, and part number before choosing a replacement.

Can I use this PCB on a Jack A2 machine?

It can work with compatible Jack A2 configurations. However, you should first compare your original PCB model, part number, connector arrangement, and machine revision with this board.

What does the Jack A2C main PCB control?

The main PCB manages important electronic functions such as direct-drive motor control, sewing speed response, needle positioning, automatic thread trimming, and communication with connected control components.

Does this PCB include the complete sewing machine control box?

No. This listing covers 1 PCB control board. The package does not automatically include the external control box, motor, operation panel, cables, or other machine components unless the product listing specifically mentions them.

How do I know whether I need an A2B or A2C PCB?

Check the model marking and part number printed on your existing PCB. A2B and A2C boards can use different electronic configurations. If your original board carries the A2B-25A marking, verify compatibility before ordering an A2C board.
