The STF1003 Tube Feeder automatically supplies tube-packed components—relays, terminals, transformers, square and round capacitors—from stacked PVC or aluminum tubes to SMT pick-and-place machines, non-standard equipment, and robotic arms. Multi-tube stacking design extends unattended operation time and reduces manual intervention.
Key Features

Applications
Perfect for high-mix PCB assembly lines handling diverse THT components in tube packaging. The multi-tube stacking capability is especially valuable for unattended production and robotic arm integration, reducing changeover frequency and labor cost.
Compatible placement machines
Running on Panasonic CM602, JUKI, Yamaha and Mirae odd-form machines. Other platforms receive a custom docking plate and IO interface after a compatibility check.
Quality testing
Every unit runs 1,000 consecutive feed cycles and a 48-hour aging test with your components before shipment, and the test video is shared with you.

FAQ
How many tubes can be stacked?
The STF1003 stacks multiple PVC or aluminium tubes (200–650 mm long, cross-section 6×10 to 30×30 mm) and changes tubes automatically, so the operator reloads a stack instead of single tubes.
Which components suit a stacked tube feeder?
Relays, terminals, transformers and square or round capacitors from 3×3×3 mm to 25×25×25 mm that are supplied in tubes.
