Sallas Industrial Co., Ltd. is a Taiwanese manufacturer of monitor arms, keyboard arms and mobile computer carts, founded in Taipei in 1987. We make our industrial mounting arms at our own plants in Pali and Changhua for factories, warehouses and equipment designers in North America, Europe and Asia. In this article we explain what to check when you choose an industrial monitor mount, so that the arm you specify fits the screen, the machine and the people who use it.
As of October 2026, choosing an industrial monitor mount involves five checks: the weight on the arm, the VESA (Video Electronics Standards Association) hole pattern, the mounting surface, the reach and adjustment the operator needs, and the finish the environment requires. The first two decide whether the mount will hold the screen, so you should confirm them first.
Which load capacity and VESA pattern does your monitor need?
An industrial monitor mount must be rated for the full weight it carries, and its interface plate must match the hole pattern on the back of the screen. Both figures are easy to find, but they are often taken from a catalog instead of from the equipment you will actually install.
Calculate the total weight on the arm
Industrial screens are often heavier than office monitors of the same size, because many have metal housings, touch panels or protective enclosures. You should also add the weight of anything else the arm will carry, such as a keyboard tray, a scanner holder or a small computer fixed behind the screen.
On Sallas arms the pivot head and the arm each carry their own rating. Our 21-01 VESA 75 pivot head is rated to 11 kg (24 lb), the heavy-duty 21-01H to 13 kg (29 lb), and our arms are rated from 1.5 kg to 13 kg (3 lb to 29 lb) depending on the model. The lower of the two ratings applies to the complete assembly, so we would suggest choosing components with a reasonable margin above the weight you have calculated.
Match the VESA hole pattern
VESA publishes the Flat Display Mounting Interface (FDMI), the standard behind the square hole patterns on the back of most flat screens. Smaller industrial displays commonly use 75 x 75 mm or 100 x 100 mm, while larger screens move to 200 x 200 mm.
Our pivot heads take VESA 75 directly. The 21-02 adapter plate converts them to VESA 100, and the 21-12 conversion plate covers 75, 100 and 200. It is worth checking the pattern on the screen you will install, since a protective enclosure or a panel PC housing may carry a different pattern from the display inside it.
Which mounting method suits your machine or workstation?
The surface you mount to determines which type of arm you can use, so it is worth deciding this early in the machine or workstation design. Sallas makes wall, pole, track, desk, ceiling and free-standing mounts, as well as mounts for two or more screens. The table below summarizes where each one is normally used.
| Mounting method | Typical use | What you should confirm |
|---|---|---|
| Wall or machine frame | A screen fixed beside a machine, on a guard panel or on a wall | Bracket type and the fixing points available on the frame |
| Pole | Several devices sharing one column at a workstation | Pole diameter and the clamp for each device |
| Track | Screens that move along a bench or an assembly line | Track profile and the sliding plate |
| Desk or bench clamp | Inspection benches, packing stations and control desks | Bench thickness and the clamping edge |
| Ceiling | Stations where the floor and bench must stay clear | Ceiling structure and overhead clearance |
| Free-standing | Locations with no suitable fixing point | Footprint and stability |
Wall and machine-frame mounts
A wall arm is the simplest way to put a screen beside a machine without taking bench space. Our 60212W adjustable arm, for example, fixes with a steel wall bracket, and you can choose either a two-ear bracket (25-12) or a die-cast bracket (25-15) to suit the surface. If the arm will be fixed to a machine frame, please confirm that the frame material and the fixing points can carry the full load at the arm’s maximum extension.
Pole and track mounts
Pole mounting suits a workstation where a monitor, a keyboard tray and other holders need to share one column. Our pole clamps and tube poles let you add or move devices along the pole without new holes in the bench. Track mounting serves a similar purpose along a bench or line, and our 21-21-1 track-mount sliding plate lets a VESA screen move to where the operator is working.
How much reach and adjustment does an industrial monitor arm need?
The arm must be able to bring the screen to a comfortable height and distance for each operator who uses the station. On a line that runs several shifts, the same screen may serve people of quite different heights, some seated and some standing, which is the main reason to specify an adjustable arm rather than a fixed bracket.
Screen height and viewing distance
The US Occupational Safety and Health Administration (OSHA) gives clear figures in its computer workstations guidance on monitors. It recommends a viewing distance of 50 to 100 cm (20 to 40 inches), with the center of the screen normally 15 to 20 degrees below horizontal eye level. These figures were written for office work, but they are a sensible starting point for a production workstation. You should check that the arm can reach those positions for both your tallest and your shortest operator.
Tilt, swivel and portrait rotation
Tilt lets the operator angle the screen away from overhead lights, which matters in factories with bright ceiling lighting. Our 60212W arm tilts 87 degrees up and 25 degrees down, swivels 180 degrees, and rotates 90 degrees between landscape and portrait. It uses a counter-force lift, so the operator can reposition the screen by hand without loosening knobs.
Cleanrooms and SEMI S8
Semiconductor equipment is usually assessed against SEMI S8, the Safety Guideline for Ergonomics Engineering of Semiconductor Manufacturing Equipment published by SEMI (Semiconductor Equipment and Materials International). The current edition is S8-0218, and it takes into account the body size, strength and range of motion of the people who operate the equipment. If your equipment will be assessed against S8, we would suggest asking your assessor which display dimensions apply, and then choosing an arm whose adjustment range covers them. We explain the display requirements in more detail in our article on monitor mounts for SEMI S8 cleanrooms.
Which materials, parts and options suit a production environment?
Our adjustable arms are made from aluminum alloy, our wall brackets are steel, and we finish our products by electroplating or powder coating. All Sallas products comply with RoHS (the European Union restriction on hazardous substances) and REACH (the European Union chemicals regulation).
Materials, finishes and cable routing
An aluminum arm keeps the moving parts light, which reduces the load on the bracket and on the machine frame behind it, while the steel bracket takes the fixing load. Both of our finishes are durable and resist flaking in normal factory use. If the station will be cleaned with strong agents, or used in a washdown or cleanroom area, please tell us at the inquiry stage so that we can confirm the most suitable finish. The 60212W also routes the monitor cables inside the arm, which keeps them away from moving parts and makes cleaning easier.
Building from modular parts
Sallas mounts are built from modular parts, so many configurations can be assembled from standard components before a custom bracket is needed. Our modular range includes pivot heads, adjustable and extension arms, foldable arms, mounting brackets, pole clamps, tube poles, trays and holders, and wheel bases for mobile carts. You can combine them with our keyboard trays and arms to build a complete operator station on a single pole or wall bracket.
3D files for your machine design
We provide full 3D models of our products and components as STEP (Standard for the Exchange of Product Model Data, ISO 10303) files with the .stp extension, which most CAD (computer-aided design) software can open. Equipment designers can place the arm in the machine model and check clearances before ordering. Please contact us and we will send the models you need.
Ordering and shipping
All Sallas products and components are made in Taiwan and shipped directly from our factory. We ship them unassembled in separate cases to reduce freight cost, and we can discuss shipping assembled units if you need them. Minimum order quantities vary by product but are usually a multiple of ten. Where a standard part does not fit your application, we also design custom components and OEM (original equipment manufacturer) brackets.
If you are specifying a monitor mount for a machine or a production line, please get in touch with our team. It helps us to know the screen model and weight, the surface you will mount to, the number of stations and any environmental requirements, and we will suggest a suitable configuration.
Frequently asked questions
What VESA pattern do industrial monitors use?
Most smaller industrial monitors use a VESA 75 x 75 mm or 100 x 100 mm hole pattern, and larger screens often use 200 x 200 mm. Sallas pivot heads take VESA 75 directly, and Sallas adapter and conversion plates cover 100 and 200. Please check the pattern on the screen or enclosure you will install, since an enclosure may differ from the bare display.
How do I calculate the load capacity I need for an industrial monitor arm?
To find the load capacity an industrial monitor arm needs, add the weight of the screen to the weight of everything else the arm will carry, such as an enclosure, keyboard tray or scanner holder. On a Sallas arm, the pivot head and the arm each have a rating, and the lower of the two applies to the assembly. We would suggest leaving a reasonable margin above your calculated weight.
Can Sallas supply 3D CAD files of its monitor arms?
Sallas provides full 3D models of its products and components as STEP files with the .stp extension, which work with most CAD software. Equipment designers can request the files by contacting Sallas directly.
Are Sallas industrial monitor mounts shipped assembled?
Sallas ships its mounts unassembled in separate cases to reduce freight cost, since the products are modular. Sallas can also ship assembled units on request.
Can I buy Sallas monitor mounts in the USA and Canada?
Customers in the USA and Canada can order directly from Sallas, which ships all products from its factory in Taiwan. Sallas is also looking for qualified distributors in a number of countries, and interested companies are welcome to get in touch.
