Selector combinator — Factorio Production Calculator
Selector combinator is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 2 × Advanced circuit, 5 × Decider combinator. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 4 raw resources: copper ore, petroleum gas, iron ore, coal.
Production chain for 60 Selector combinator / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Copper cable | 7,200 | 60 | Assembling machine |
| Copper plate | 3,600 | 192 | Furnace |
| Electronic circuit | 1,740 | 29 | Assembling machine |
| Iron plate | 1,740 | 92.8 | Furnace |
| Decider combinator | 300 | 5 | Assembling machine |
| Plastic bar | 240 | 2 | Chemical plant |
| Advanced circuit | 120 | 24 | Assembling machine |
| Selector combinator | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Copper ore | 3,600 |
| Petroleum gas | 2,400 |
| Iron ore | 1,740 |
| Coal | 120 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Selector combinator recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Advanced circuit × 2, Decider combinator × 5 |
What the whole chain needs
60 selector combinators per minute pulls in 7 intermediate products, and the whole tree comes to 406 machines across 3 machine types, fed by 4 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 3,600 per minute, which is 4 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses selector combinator
No base-game recipe consumes selector combinator — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What selector combinator is made from
- Advanced circuit — 2 per craft
- Decider combinator — 5 per craft
FAQ
How many assembling machines do I need for 60 selector combinators per minute?
1 assembling machine. One at standard speed produces 60 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does selector combinator take?
At 60/min the chain consumes 3,600 copper ore per minute, 2,400 petroleum gas per minute, 1,740 iron ore per minute and 1 more. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
