S4000 Axial Auto Insertion Machine: Component Compatibility and Feeder Setup Guide
Which axial components can the S4000 insert, and how should you plan the Feeder setup before quoting a THT line? Southern Machinery, the Shenzhen-based SMT/THT PCB assembly automation specialist founded in 2011, explains what the S4000 accepts — taped resistors, diodes and jumper wires — and the real parameters buyers need to confirm for their BOM.
What is this machine used for?
The S4000 is an automatic axial component insertion machine. It places tape-packed axial-lead components — resistors, diodes, jumper wires and other compatible axial-lead parts — into a PCB automatically, replacing manual THT insertion. It is built for electronics manufacturers and EMS factories that need efficient, flexible and repeatable axial insertion on a production line.
It is not a radial inserter and not an odd-form inserter: it is the axial workhorse of a THT line, and it is usually paired with radial and odd-form machines to cover the full through-hole component mix.
Which axial components can the S4000 handle?
The S4000 is designed for tape-packed axial components, and Southern Machinery documents three mainstream groups:
- Resistors — the most common axial part, in standard tape packaging.
- Diodes — axial-lead diodes in tape format.
- Jumper wires — axial jumpers/links used to bridge traces on single-sided or double-sided PCBs.
The selection question buyers must answer first is: is my component available in axial tape? If yes, check the two geometry limits below. If your component is loose, bulk or in a tube, an axial inserter is not the right first machine — confirm a custom feeding solution with Southern Machinery instead.
Lead diameter range
The S4000 supports axial lead diameters from 0.3 mm to 0.8 mm. Components outside this range need evaluation, and possibly custom tooling, before a quotation.
Lead span range
The S4000 supports component lead spans from 5 mm to 20 mm — the distance between the two bends of the axial part. Parts with a wider span are handled on other platforms (for example, Southern Machinery's wide-span radial solutions for XL 15 mm and above), so it is worth confirming span limits early with the machine's insertion head geometry.
Feeder station planning: how many stations do you need?
The S4000 uses a modular Feeder configuration with 5 to 60 Feeder stations. This is one of the most important planning parameters because it directly maps to your BOM:
- Count the unique axial part numbers in your BOM (resistor values, diode types, jumper lengths).
- Each unique part number needs its own station or a shared station with changeover planning.
- For high-mix EMS work, lean toward the upper station range; for dedicated power-supply or LED boards with a small part count, 5-20 stations may be enough.
- Power supply PCBs — high volumes of axial resistors and diodes on power boards, where manual insertion is the bottleneck.
- LED lighting PCBs — driver and lamp boards with repeatable axial part patterns.
- Appliance control boards — air conditioner, induction cooker, rice cooker and other appliance PCBs with mixed THT components.
- EMS/ODM lines — replacing manual insertion stations with an inline automatic inserter to stabilize quality and throughput.
- Automotive and industrial electronics — where solder-joint consistency and traceability matter, and MES integration is expected.
- Automatic PCB loading is supported, so boards can be fed from an upstream conveyor or loader.
- MES-ready integration: the EtherCAT bus and MES compatibility allow production data collection, program traceability and line-level monitoring.
- Upstream: PCB loader → SMT placement (if a mixed SMT/THT board) → axial insertion.
- Downstream: radial insertion and odd-form insertion stations → Wave Soldering → AOI/inspection → lead cutting or depaneling.
- Capacity: rated up to 20,000 CPH, with roughly 10,000 CPH typical in real production — far beyond manual insertion rates.
- Consistency: automatic insertion removes the human variability of hand placement, reducing polarity errors and missed insertions.
- Labor: one machine replaces several manual insertion stations, which matters in high-labor-cost regions and in factories where recruiting operators is the constraint.
- Quality: consistent lead clinching and placement reduce rework and re-inspection downstream of the line.
- Factory ROI: for EMS and ODM buyers, the payback is driven by labor savings plus defect reduction; Southern Machinery can help configure the machine to your actual mix before you commit.

The S4000 is a full servo-driven machine with an EtherCAT motion-control bus and a Windows-based industrial computer, so program and station data are managed in software. Southern Machinery also offers a software editing training video, which operators can use to learn board programming before the machine arrives.
Typical application scenarios
How the S4000 connects into a complete PCB assembly line
The S4000 is designed for production-line integration:
Southern Machinery positions itself as a full-line solution provider: SMT, THT, Wave Soldering, board handling and inspection equipment can all be sourced from one supplier, which simplifies line engineering, training and after-sales support. The company serves 237+ global customers across EMS, power supply, LED, appliance and automotive electronics.
Key selection parameters checklist
Use this checklist when evaluating the S4000 against your BOM. Only the documented parameters are listed; anything else should be confirmed in writing before purchase.
| Parameter | What to verify |
|---|---|
| Component packaging | Axial tape only — confirm your parts are taped |
| Lead diameter | 0.3 - 0.8 mm documented range |
| Lead span | 5 - 20 mm documented range |
| Feeder stations | Modular, 5 - 60 stations; match to unique part count |
| Rated speed | Up to 20,000 CPH (rated); typical actual production approx. 10,000 CPH |
| Motion control | Full servo + EtherCAT bus |
| Control system | Windows-based industrial computer |
| MES integration | Compatible with MES production management systems |
| PCB loading | Automatic PCB loading for inline operation |
| Maintenance | Drawer-style control box |
| Board size | Confirm your max PCB dimensions with the supplier |
| Clinch requirement | Confirm clinch type (inward/outward) for your joint spec |
Do not assume speed, board size or clinch behavior from the rated values alone — always validate with Southern Machinery using your board data and target volume.

FAQ
Can the S4000 insert radial components like capacitors or LEDs?
No. The S4000 is an axial inserter for tape-packed axial components. Radial components (capacitors, LEDs, transistors) are handled by radial insertion machines, and non-standard parts by odd-form inserters.
What is the real production speed of the S4000?
Southern Machinery documents a rated speed up to 20,000 CPH, with typical actual production around 10,000 CPH depending on board layout and component mix.
Does the S4000 work with a MES system?
Yes. The machine uses an EtherCAT motion-control bus and is compatible with MES production management systems, supporting traceability and line-level data collection.
What PCB sizes can the S4000 process?
The documented product page lists board handling with automatic PCB loading, but max PCB dimensions should be confirmed with Southern Machinery against your specific boards — do not assume from the machine's footprint.
Is the S4000 suitable for high-mix EMS production?
Yes, within its axial scope. The modular 5-60 station Feeder configuration and software-based programming support multiple part numbers, and the Windows-based control system simplifies program management for changeovers.
