The Omron R88M-K40030L-S2 is a 400 W servo motor from the OMNUC G5-Series, rated for 100 VAC input and 3000 r/min rated speed. It ships with key and tap — meaning the shaft key and the mating tap for the encoder connector are included, so you don't need to chase those as separate line items on a rebuild or retrofit.

Frequently asked questions
Where can I buy the R88M-K40030L-S2 and get a price?
We source it to order through independent distribution. Submit an RFQ — we confirm current availability and pricing at quote time. No stock count or price is published here because the EOL status makes both variable.
What is the closest pin-compatible alternative to the R88M-K40030L-S2?
No official successor order code is listed by Omron. A parametric match — 400 W, 100 VAC, 3000 r/min, with key and tap — would be the starting point. We can help identify a candidate when you send the RFQ with your drive model and connector pinout.
What compliance documentation does Omron provide for this motor?
The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC) for this part. Typical for the OMNUC G5-Series, Omron provides a CE declaration and UL recognition on the nameplate, but confirm with the RFQ if you need a cert copy for your quality file.
