Panasonic CM402 NPM 8mm Feeder Gear N210047118AB KXFA1KMAA01
About This Panasonic CM402 NPM 8mm Roll Stock Gear
This gear sits in the tape path of a Panasonic CM402 or NPM 8mm feeder. Its teeth drop into the perforations down the edge of the carrier tape, and the feeder turns it once per cycle, which is what walks the tape forward by one component pitch and lines the next part up under the nozzle.
Four numbers are used for it: N210047118AB, KXFA1KMAA01, MTKP003990AA and N210047118AA. A feeder that has been through several rebuilds often carries a gear whose number does not match the parts book, so the number engraved on the old gear is worth reading before an order is placed.
The gear is a wearing part rather than a service part. Teeth that have rounded off, or a hub that no longer holds its position, are what send a feeder back to the bench, and the symptom at the machine is a tape that moves short or jumps a pocket.

Gear Mesh Function & 8mm Tape Indexing Mechanism
The tooth form and the pitch of the tape go together. On an 8mm carrier tape the perforations sit on a fixed spacing, and the gear has to land in them on every revolution; when it does, the tape advances by exactly one pocket and the pick position repeats. That is why a gear with worn teeth does not stop the feeder, it makes the feeder unreliable.
Two things are commonly got wrong when one is ordered. The first is the number, since the four numbers in use look alike on a bench. The second is assuming the gear is at fault when the count comes up short: a tape that has stretched, or a tape guide that has come loose, will give the same symptom with the gear in perfect condition.
The tooth count and the pitch of this gear are not recorded for the part, so they are not stated here. Match the number, and where the old gear carries no readable mark, send a photograph of its face together with the machine model.
Four Part Numbers Cross-Reference & Machine Compatibility
The gear is quoted under four numbers, and any of them can be used when the enquiry is placed:
- N210047118AB
- KXFA1KMAA01
- MTKP003990AA
- N210047118AA
They are the alternatives recorded for the same position in the 8mm feeder, so the number to quote is the one on your parts list, or the one engraved on the gear being replaced. Where a machine has been built up from more than one feeder, the numbers that differ only in their final letters are worth checking against the feeder body before the order goes in.
The gear is listed for Panasonic CM402 and NPM 8mm feeders.
Material Inspection, Available Conditions & Packaging
Two supply states are recorded on this number: new, and new or used units, so name the one you want with the enquiry.
On arrival, three checks answer the questions a bench fitter would ask: the tooth flanks for rounding or chipping, the hub bore and its locating features for wear, and a hand turn of the feeder with the gear fitted to be sure it engages the tape perforations across a full revolution.
Packing is recorded as a wooden case for this number.
