S-350C
S-350C PCB Buffer Conveyor
S-350C PCB conveyor: 0.5/1.0/1.5 m rails, 50–500 mm width ranges, 900±20 mm height, 0–2 m/min, SMEMA, anti-static belt and ESD inspection surface.
Keep boards moving between machines.
The S-350C links PCB equipment with adjustable parallel rails and gives the operator an accessible inspection position on an ESD work surface.
Rail length, width range and direction are selected for your line; SMEMA signals connect it to the machines on either side.

At a glance
- 0.5 / 1.0 / 1.5 m — rail length options
- 50–250/300/400/500 mm — conveyor width ranges
- 900 ± 20 mm — conveyor height
- 0–2 m/min — conveyor speed
- SMEMA — signal plug to other devices
- ≈ 40 W — power consumption
The short space between machines deserves its own specification
A board can leave one machine correctly and still arrive badly at the next.
- Unequal heights: Mismatched transfer heights cause jams and operator intervention.
- Unexpected direction: Travel direction must match the line flow.
- Weak edge support: Boards need parallel rails set to their width.
- No inspection position: Squeezed conveyors leave poor access for checking boards.
S-350C features — Feature, Advantage, Benefit
Four functions from the S-350C specification.
Rails: Parallel width adjustment
Exact thread shaft structure.
- Feature: An exact thread shaft structure keeps the rails parallel during width adjustment; strengthened aluminium alloy rails with durable anti-static belts.
- Advantage: Boards are supported on both edges at every width.
- Benefit: Reliable transfer with less board damage.
Key points: Parallel rails · Anti-static belt · Aluminium alloy rail
Interface: SMEMA communication
Talks to the machines on either side.
- Feature: Communicates with other devices through a SMEMA signal plug; relay board control with 2 sensors (without stopper).
- Advantage: Boards move only when the next machine is ready.
- Benefit: No collisions or stalled boards at the handoff.
Key points: SMEMA · Relay board · 2 sensors
Inspection: Operator work surface
Inspection position on the line.
- Feature: A green ESD work surface beside the fixed rail gives the operator a defined working area next to the transport path.
- Advantage: Boards can be checked without leaving the line.
- Benefit: Visual inspection becomes a station, not a detour.
Key points: ESD work mat · Front fix rail · Accessible position
Configuration: Configured for your line
Length, width, direction.
- Feature: Rail length 0.5, 1.0 or 1.5 m; width ranges up to 250, 300, 400 or 500 mm; L→R or R→L; front-fixed rail with rear-fixed option.
- Advantage: One conveyor family covers different line gaps and board sizes.
- Benefit: Consistent spares and setup across the plant.
Key points: 0.5–1.5 m · L→R or R→L · Front / rear fix

S-350C machine and details
Watch the equipment
Plan the handoff before installation
- 1 · Share the board — PCB size, thickness, board edge and component clearance.
- 2 · Check the interface — Direction, transfer height and adjacent equipment.
- 3 · Review the layout — Rail length, footprint and access.
- 4 · Approve the configuration — Specification and a transfer trial agreed in writing.
