FAQ Guide — KHJ-MC1A9-00
Electric Feeder Communication Connector (Without White Wire)
1. What is the KHJ-MC1A9-00 used for?
It is a signal and power interface connector for Yamaha electric
(motorized) feeders, allowing communication between the feeder and
the SMT placement machine.
2. What does "no white wire" mean?
The white wire typically carries an optional signal line (such as a
feeder-ready status or ground reference). In this version, it is
intentionally omitted, which is common for simplified or specific
wiring configurations.
3. Which feeders use KHJ-MC1A9-00?
It is used in Yamaha SS-series electric feeders, such as SS8MM,
SS12MM, etc., particularly those without the extra signal line
requirement.
4. Can this connector be replaced individually?
Yes, it can be replaced separately as part of routine maintenance
or repair without replacing the full harness or motherboard.
5. Does the lack of a white wire affect performance?
No, if your system is designed for this configuration, the absence
of the white wire has no negative impact. Always verify
compatibility with your specific machine and feeder model.
6. How is the connector attached?
It is typically connected to the feeder’s motherboard
(KHJ-MC1A0-00) via the cable harness (KHJ-MC1B0-00) and secured
with standard Yamaha mounting hardware or connector clips.
7. Is this part machine-side or feeder-side?
It is a feeder-side component that plugs into the machine’s feeder
slot electrical interface.
8. What if I need a version with the white wire?
You would need to order a different part number (e.g., KHJ-MC1A9-01
or custom harness with full wire set). Confirm with Yamaha or your
SMT supplier.
9. Where can I buy KHJ-MC1A9-00?
Available through authorized Yamaha SMT parts distributors,
third-party feeder repair services, or SMT spare parts suppliers.
10. Any maintenance or inspection tips?
Inspect for bent or oxidized pins regularly
Do not pull wires directly; always grip the connector body
Ensure tight fit into the machine socket; loose connections can
cause feeder communication errors
