SIASUN SA4A-4/0.40 (SA4A-4/0.40)

On many electronics lines the scarce resource is not floor space but headroom: a fixture below, a camera bracket or a feeder above, and only a narrow band of air in between for a robot to work in. The SIASUN SA4A-4/0.40 (SA4A-4/0.40) was designed with that band in mind. It is a SCARA robot from SIASUN's new SA4A generation, built with a lower overall height and a compact body, so that a fast, precise four-axis arm fits into cells where a taller machine would collide with the equipment around it. It does not try to be the biggest arm in the range. It tries to be the one that fits.

Robots Europa, based in Dublin, sells the SIASUN SA4A-4/0.40 and supplies it to manufacturers and system integrators throughout the European Union and the DACH region. Robots Europa prepares each quotation, coordinates delivery to your site and remains your point of contact for support once the robot is installed, so that a single partner handles the project from enquiry to commissioning.

Background

SIASUN and two decades of engineering validation

SIASUN is a robotics manufacturer with over two decades of engineering validation and thousands of project experiences behind its product lines. The company combines its robot products with application know-how to deliver value-added services, an approach that has earned it customer trust internationally. Its portfolio spans several families of industrial robots, and the SCARA range is the part of that portfolio aimed at fast, repetitive work in a horizontal plane: assembly, handling and placing tasks where speed and repeatability matter more than a long reach or a heavy payload.

A new SCARA generation built on independent core components

The SA4A series is a new generation of SCARA robots launched by SIASUN. Its foundation is a set of brand-new independent core components, which the manufacturer developed to deliver stronger load capacity, higher precision, faster speed, better rigidity and less vibration than before. Around that core sits a lightweight, compact structure: the main body is lighter, deployment is convenient and simple, and the lower overall height reduces the spatial constraints that often dictate how a cell is laid out. On the usability side, the main unit carries abundant user cables, works with a new generation of S series control cabinet and supports multiple programming and teaching methods. SIASUN positions this combination as a way to meet more automation scenarios while keeping the overall cost of the machine under control.

Technical Specifications

The manufacturer has not published the weight, power supply, maximum speed, cycle time, mounting method, controller model designation, communication interfaces, operating temperature or the contents of the delivery; Robots Europa confirms these details at quotation.

Why does a lower overall height matter in a SCARA cell?

A SCARA robot moves its arm in a horizontal plane and raises or lowers its tool along a vertical axis. The height of the column and the arm assembly therefore decides how much vertical clearance a cell needs, and that clearance is frequently the hardest thing to find on an existing line. Enclosures, overhead vision systems, light curtains and feeding equipment all compete for the same space above the work surface.

By lowering the overall height, the SA4A-4/0.40 reduces those spatial constraints. In practice this gives a planner more freedom: the robot can sit inside a compact enclosure, work beneath equipment mounted above the line, or be placed in a benchtop cell that would not accommodate a taller machine. Combined with the compact body and high-speed cycle times SIASUN designed into the series, the result is an arm that adapts to a wider range of application scenarios rather than one that forces the cell to be built around it.

The lighter main body supports the same goal. A lighter robot is easier to handle during installation and relocation, which matters to manufacturers who retool lines frequently as product generations change, as is common in consumer electronics.

What does IP20 protection mean for where the SA4A-4/0.40 can work?

The SA4A-4/0.40 carries an IP20 protection rating. Under the IP classification, this level protects against contact with fingers and larger solid objects but offers no specific protection against water or fine dust. The robot is therefore suited to clean, dry indoor environments, which is exactly the kind of setting found in electronics assembly and automotive electronics production. Where a process involves coolant, washdown, splashing liquids or heavy particulate, the application should be discussed with Robots Europa before quotation so that the environment can be assessed properly.

Who is the SIASUN SA4A-4/0.40 for?

SIASUN states that the SA4A series is mainly used in industries such as 3C — computers, communications and consumer electronics — and automotive electronics. These sectors share a profile that suits a compact SCARA: small, light components, tight positional tolerances, high volumes and frequent product changeovers.

Electronics manufacturers assembling devices, modules and sub-assemblies are the most natural buyers. The 4 kg (8.8 lbs) payload and 400mm reach cover grippers, suction tools and small screwdriving or dispensing heads working over a compact area, and the repeatability of ±0.01mm on J1+J2 and J3 supports precise placement.

Suppliers of automotive electronics — control units, sensors, connectors and wiring components — form the second core group, where consistent, repeatable assembly steps are central to quality.

System integrators are a third audience. The abundant user cables on the main unit, the S series control cabinet and the support for multiple programming and teaching methods make the robot straightforward to build into turnkey cells for end customers.

Buyers whose parts or tooling are heavier, or whose work area is larger, may be better served by a bigger model in SIASUN's SCARA family, such as the SIASUN SA7A-7/0.50 (SA7A-7/0.50), the SIASUN SA10A-10/0.60 (SA10A-10/0.60) or the SIASUN SA20A-20/0.80 (SA20A-20/0.80); Robots Europa can compare their datasheets with your requirements. The full range is listed in the SCARA category and among SIASUN's Industrial Robots.

What is the SIASUN SA4A-4/0.40 used for?

1. Small-part pick-and-place: moving components between trays, feeders and fixtures at high cycle rates.
2. Electronic assembly: placing parts on circuit boards or into housings in consumer electronics production.
3. Screw driving: carrying a compact screwdriving head to fasten covers and modules in a repeatable sequence.
4. Connector and module insertion: fitting connectors and sub-assemblies in automotive electronics lines.
5. Dispensing and gluing: guiding an adhesive or sealant applicator along a defined path over a small work area.
6. Test and inspection loading: feeding parts into test stations or presenting them to vision systems.
