SIASUN SA20A-20/1.00 (SA20A-20/1.00)

In a SCARA cell, the fastest point is not the conveyor or the gripper but the tip of the arm, sweeping across the work surface on every cycle. Extend that arm to a full metre and a harder question follows: can it stay quick and accurate at the far edge of its envelope? The SIASUN SA20A-20/1.00 (SA20A-20/1.00) answers with a 1000 mm reach, a combined J1+J2 speed of 10800 mm/s and a takt time of 0.43 s, while holding J1+J2 repeatability of ±0.025mm. It is a long-reach SCARA for layouts where the spacing between stations cannot shrink and the cycle cannot slow down.

Robots Middle East supplies the SIASUN SA20A-20/1.00 to manufacturers, system integrators and research institutions across the Middle East. Our team prepares each quotation around the intended application, arranges delivery to your facility and remains your point of contact for technical support once the robot is installed and running.

Background

SIASUN and its SCARA family

SIASUN is a Chinese robotics manufacturer whose industrial portfolio includes a structured family of SCARA robots. The range climbs in steps, from compact models such as the SIASUN SA4A-4/0.40 (SA4A-4/0.40), through the SA7A and SA10A series, to the SA20A series at the heavier end. Because each model code states its series and version, buyers can move along the line as their loads and layouts change, keeping a single manufacturer and a familiar approach to programming and maintenance across several cells. The complete range is gathered in our SCARA category.

Where the SA20A-20/1.00 sits in the line

The SA20A series comprises two versions, the SA20A-20/0.80 and the SA20A-20/1.00. This page covers the latter, the version with the 1000 mm reach. Like every SCARA, it works through four joints: J1 and J2 rotate in the horizontal plane to position the tool, J3 moves it vertically, and J4 rotates it about its own axis. That architecture makes the SCARA a natural choice for work that is planar in character, such as picking, placing, inserting and fastening, where a six-axis arm would bring more freedom than the task needs. The SA20A-20/1.00 brings that principle to larger parts and wider work areas, with a maximum payload of 20 kg and a J1 motion range of ±142°.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

SIASUN has not published the power supply requirements, the controller model, the communication interfaces, the package contents, the operating temperature range or the mounting orientation for this version; Robots Middle East confirms each of them at quotation.

Should you plan around the rated or the maximum payload?

The SA20A-20/1.00 carries two load figures, and each answers a different question. The rated payload of 10 kg is the figure to design routine production around: the mass the arm handles cycle after cycle. The maximum payload of 20 kg is the ceiling, the heaviest load the arm accepts. A sound cell design keeps the everyday load, including the gripper, any tool changer and the part itself, comfortably within the rated value, and treats the maximum as headroom for occasional heavier items rather than a target.

This matters most at the end of a long arm. The mass at the tool affects how quickly the arm can accelerate and settle, so the takt time of 0.43 s and the J1+J2 speed of 10800 mm/s are best treated as reference points when the cell is designed. When you share your part mass, tooling and target cycle with us, Robots Middle East reviews the application before the quotation is issued.

What does IP20 mean for where the SA20A-20/1.00 can be installed?

Under the IEC ingress protection scheme, IP20 indicates protection against solid objects larger than a finger and no specified protection against water. In practical terms, the SA20A-20/1.00 belongs in clean, dry, indoor production areas: assembly halls, electronics lines, packaging rooms and laboratories. Washdown areas, cells exposed to coolant spray and environments with heavy airborne dust call for additional protective measures or a different robot class.

Two further details help with the physical layout. The base uses a 200×200 mounting-hole pattern, which gives the mechanical designer a defined footprint for the pedestal or base plate. The standard cable length of 3 m, with optional lengths of 5 m and 10 m, allows the control cabinet to be placed outside the guarded area or at a convenient service point, which simplifies maintenance access and cell guarding.

Who is the SIASUN SA20A-20/1.00 for?

System integrators are the first audience: the combination of a 1000 mm reach and a 20 kg maximum payload lets them cover wide stations with a single arm instead of two shorter ones, which can simplify the layout and the programming effort. Production and manufacturing engineers in plants form the second group, particularly those replacing manual handling of heavier components, where the rated payload of 10 kg covers a broad range of routine parts and the repeatability supports consistent placement.

Research institutions and technical training centres are a third segment, using a long-reach SCARA to study cell design, cycle optimisation and vision-guided handling on an industrial-scale arm.

Not every cell needs a metre of reach. Where the workstation is more compact, it is worth comparing the SIASUN SA20A-20/0.80 (SA20A-20/0.80), the other version of the series; its figures are set out on its own page. Where the parts are lighter, the SIASUN SA10A-10/0.80 (SA10A-10/0.80) may be the more proportionate choice. For applications that go beyond planar work, our Industrial Robots category shows the wider SIASUN range.

What is the SIASUN SA20A-20/1.00 used for?

1. Long-reach pick-and-place: moving parts between widely spaced conveyors, trays and fixtures with a single arm.
2. Machine tending: loading and unloading presses, test stations and processing equipment where the arm must reach across a machine bed.
3. Assembly of heavier components: placing housings, sub-assemblies and modules that exceed the capacity of compact SCARA models.
4. Insertion and fastening: using the fine J3 and J4 repeatability for press-fitting, screwdriving and connector insertion.
5. Tray and carrier loading: filling and emptying trays, carriers and kitting boxes across a broad work surface.
6. Inspection handling: presenting parts to cameras, gauges and test fixtures in a repeatable position and orientation.

What load can the SA20A-20/1.00 carry?

The rated payload is 10 kg and the maximum payload is 20 kg. Routine production should be planned around the rated figure, including the mass of the gripper and tooling.

How repeatable is the SA20A-20/1.00?

Can the SA20A-20/1.00 be used in wet or dusty environments?

The robot is rated IP20, which corresponds to clean, dry indoor environments. Areas with water exposure or heavy dust require additional protection or a different robot class.

Summary

A long arm usually asks the buyer to accept a trade-off between reach and pace. The SIASUN SA20A-20/1.00 is built to narrow that trade-off: 1000 mm of reach, a combined J1+J2 speed of 10800 mm/s and a 0.43 s takt time, with repeatability that stays fine on every axis. Its IP20 rating places it in clean indoor production, its defined mounting pattern and cable options simplify cell design, and its rated and maximum payloads give a clear frame for tooling choices. For a manufacturer or integrator in the Middle East planning a wide, fast SCARA cell with Robots Middle East, this page is the starting point.
