1. What is the KHJ-MC1A2-00?

It is the front protective cover for the internal control board (motherboard) of Yamaha SS8MM feeders, shielding electronic components from external damage and contaminants.

2. What components does this cover protect?

It protects the main motherboard (KHJ-MC1A0-00), the cable harness (KHJ-MC1B0-00), and other nearby electronic elements from dust, impact, and electrostatic discharge.

3. How does it differ from KHJ-MC1A1-00?

KHJ-MC1A2-00: Front cover
KHJ-MC1A1-00: Rear cover
Together, they fully enclose and protect the motherboard assembly inside the SS8MM feeder.

4. What is it made of?

Made of ESD-safe engineering plastic, which is lightweight, durable, and non-conductive, ideal for sensitive electronic areas.

5. How is it installed?

It is mounted using standard Yamaha screws or clips onto the feeder frame (KHJ-MC10A-00). No special tools are required.

6. When should the cover be replaced?

Replace it if:

It is cracked or deformed
It no longer fits securely
The internal board is exposed or vulnerable

7. Does this cover affect the feeder’s function?

Indirectly, yes. While it does not move or feed tape, it protects the motherboard, which is essential for reliable feeder communication and operation.

8. Is it interchangeable with other feeder sizes?

No. This part is specifically designed for SS8MM feeders. Other feeder sizes (12mm, 16mm, etc.) use different covers.
