SZGH T950-A-6 — 6-Axis Lightweight Robot Arm

What Is the SZGH T950-A-6?

The SZGH T950-A-6 is a six-axis articulated industrial robot engineered for applications where part fragility and placement accuracy matter more than raw lifting power — delivering a 950 mm working radius, ±0.05 mm repeatability, and a 3 kg payload ceiling purpose-matched to electronics assembly, camera-guided visual inspection, and precision pick-and-place of lightweight components.

Key Advantages

The Lowest Payload in the T Series — and That Is Exactly the Point

At 3 kg, the T950-A-6 is matched to parts that heavier robots handle poorly. Where a 10 kg-payload robot drives too much inertia into a delicate PCB or glass lens, the T950-A-6 completes the same pick-and-place cycle with 60–70% less wrist force — eliminating micro-cracks, scuffs, and positional bounce that show up downstream in quality inspection.

±0.05 mm Repeatability Across All Six Axes

The ±0.05 mm figure is not a best-case lab number — it is the spec held across the full 360° range of Axis 6 and the full ±150° swing of Axis 4. In inline camera-guided inspection cells, this means the robot returns to teach points consistently enough that vision offsets stay within one pixel across shifts without manual recalibration.

950 mm Reach Covers the Standard Single-Station Footprint

A 950 mm horizontal reach fills the working envelope of most single-station assembly jigs and standard conveyor widths (400–600 mm) with clearance to spare. You get full coverage without overspecifying reach — and the arm stays compact enough to mount on brackets or ceiling tracks in tight cells.

Three Mounting Options Without Additional Hardware

Ground-mount for free-standing cells, bracket-mount for machine-integrated solutions, and ceiling-mount for overhead pick lanes — all supported natively without modification to the base casting. Repurposing the robot to a new layout is a matter of re-fixturing and re-teaching, not buying a new robot.

~86 kg Body Weight — Relocatable Without a Crane

At 86 kg the T950-A-6 can be moved with a standard pallet jack and repositioned between lines during a weekend shift change. For electronics contract manufacturers who reconfigure cells seasonally, this matters as much as the motion spec.

Customer Story — Fannie Chen

"The PCBs were fine. The previous robot was the problem."

A PCB contract manufacturer in Penang, Malaysia reached out to us in Q3 2024. They were running a camera-guided inspection cell that was supposed to pick finished PCBs from a conveyor, present them to an overhead AOI camera, and place rejected boards into a separate bin. The robot they had — a general-purpose 10 kg arm from another supplier — was technically capable of the motion. The problem was inertia.

When a 10 kg-payload robot extends its wrist at 222 °/sec to pick a 2.5 kg PCB, the stopping jolt at the end of the trajectory is absorbed partly by the servo brakes and partly by the part itself. Their boards were showing hairline solder joint cracks at rate they could not explain until a vibration analysis consultant pointed to the robot deceleration signature.

We recommended the T950-A-6. The 3 kg payload ceiling meant the arm's motion profile was tuned for lighter loads — the servo gains, acceleration ramps, and path interpolation all behave differently than on a 10 kg machine. The wrist deceleration in the same pick cycle dropped by roughly 65%. Solder joint crack rate at final test went from 0.8% to under 0.1% within the first week.

The ±0.05 mm repeatability also meant the vision system's pixel-to-millimeter calibration held across shifts without manual touchup — something the previous robot required every morning due to thermal drift in the heavier servo pack.

That customer now runs three T950-A-6 units on the same line and has referred us to two other Penang facilities. The lesson I take from this: matching the robot to the part weight is not just about cost — it is about physics. A robot that can lift 10 kg does not automatically handle 2.5 kg better than one built for 3 kg.

Control System & Integration

The T950-A-6 ships with the SZGH CNC-G9 controller as standard — the same controller platform used across the T series, which means programs, coordinate frames, and operator training transfer directly when you scale to additional axes or larger models.

Standard Integration Features:

• EtherCAT real-time fieldbus for sub-millisecond cycle sync with conveyor PLCs

• Modbus TCP and Profinet for Siemens / Mitsubishi / Omron PLC environments

• Built-in vision interface for direct camera trigger and offset correction

• Teach pendant with 7-inch color touchscreen; supports offline programming via SZGH Studio software

• Safety I/O: dual-channel E-stop, safety door interlocks, configurable speed reduction zones

Optional Packages:

• Vacuum gripper kit (SMC or Festo compatible)

• 2D/3D inline vision bundle

• Conveyor tracking (encoder input, up to 2 m/min belt speed)

• Extended cable carrier for ceiling or gantry mounting

Frequently Asked Questions

1. What is the maximum part weight the T950-A-6 can handle?

The rated payload is 3 kg at the wrist flange. This includes the weight of the end-effector (gripper, camera bracket, vacuum cup assembly). If your gripper weighs 0.5 kg, your part weight budget is 2.5 kg. Exceeding the rated payload does not immediately cause failure but will reduce repeatability and shorten servo life.

2. How does ±0.05 mm repeatability compare to other small 6-axis robots?

±0.05 mm is standard for T-series. Many entry-level small robots spec ±0.1 mm or worse. In camera-guided inspection or fine component placement, the difference between ±0.05 mm and ±0.1 mm translates directly to tighter pixel windows and fewer false rejects. We verify this figure on every unit during factory acceptance testing.

3. Can the T950-A-6 be ceiling-mounted without additional hardware?

Yes. The base casting is symmetrical and pre-drilled for overhead installation. You will need to invert the motion limits in the controller (one parameter change) and verify that cable routing does not create tension at full Axis 6 rotation. Our integration guide covers both steps.

4. What vision systems are compatible?

The robot's controller includes a dedicated vision interface that outputs trigger signals and accepts X/Y/Z/Rx/Ry/Rz offset corrections from any camera that can output TCP/IP ASCII strings. Tested integrations include Cognex In-Sight, Keyence CV-X, and Basler Ace with custom wrapper. We also offer a bundled SZGH vision kit for customers who prefer a single-source solution.

5. What is the minimum recommended teaching time for an operator new to SZGH robots?

Most customers report production-ready programs within 3–5 days for simple pick-and-place with fixed teach points, and 1–2 weeks for vision-guided applications. SZGH provides remote commissioning support via video call and can upload reference programs for common applications (PCB handling, tray sorting) to shorten startup.

6. Is the T950-A-6 suitable for cleanroom environments?

The standard model is rated for industrial environments (IP54 wrist). For Class 1000 or better cleanroom use, contact us — a cleanroom variant with sealed joints and anti-static coatings is available on request.

7. How does the T950-A-6 differ from the T750-B-6?

The T750-B-6 has a shorter 750 mm reach and ~75 kg body weight — better for very compact cells or tabletop integration. The T950-A-6's extra 200 mm reach gives it more flexibility for standard conveyor-width applications. Both carry 3 kg and share ±0.05 mm repeatability.

8. What lead time should I expect for a T950-A-6 order?

Standard orders ship within 15–20 business days from Shenzhen. For orders of 3 or more units, we recommend confirming with our sales team for current stock status. Air freight to Malaysia, India, or Southeast Asia typically delivers within 5–7 business days after dispatch.
