Time for Something Sweet?

Ever have that inescapable need for a little something sweet? Good things in small packages applies not just to fine confectioneries, but also to the world of industrial machine vision: Sugarcube is a term that has grown in importance in the industry in recent years. It represents a trend in vision technology towards miniaturization.

The Sugarcube in Industrial Machine Vision

The term refers to small cameras sized at 29 mm x 29 mm, which has become an unofficial but de-facto standard. The so-called "Sugarcube" design encompasses industrial cameras in the entry level and lower mainstream segments, covering a variety of classic operations in many different markets such as Medicine, Traffic and Transportation and Retail, as well as for Quality Assurance and Automated Optical Inspection in the field of Factory Automation.

Small Format, Grand Innovation

The trend toward small form factors was observed as far back as 20 years ago in analog cameras, with echoes during the rise of FireWire and later Gigabit Ethernet. It's unlikely to end with current modern interface technologies such as USB 3.0. All notable technical innovations, such as high-resolution sensors and comprehensive firmware features, are packed onto or into these minute dimensions. Analog cameras at this point can now also process their image data within a small housing instead of sending it on to an external processing unit.

Important Considerations

  • When planning a new or redesigning an existing machine vision system, care should be taken from the start to build around small sizes so as to avoid space issues later.
  • For redesigns in particular, small footprints should be maintained. Switching over to large formats can bring major mechanical challenges.

Small Sensors = Small Cameras

A camera's size is reflective at least in part by the size of its sensor. Larger sensors, typically using CCD technology, do not work in these small standard sizes. Such cases are becoming increasingly rare as the machine vision world shifts further and further toward CMOS for its sensor technology. Small, extremely powerful sensors with small pixel sizes are selling better than ever on the market, and are expected to replace the standard 29 mm x 44 mm size commonly seen today.

Productive, Affordable, Flexible

The small 29 mm x 29 mm format is the best way to achieve top throughput rates at the lowest costs possible. This size has established itself not just for its external appearance (camera front), but also for its drilling pattern. Most camera makers have harmonized their offerings to work with it, which gives customers significantly more flexibility.

Traditional CCD sensors were typically built around larger dimensions, such as 40-45 mm x 40-45 mm. The trend toward smaller CMOS sensors means those larger dimensions are likely to shrink into niche areas of the machine vision market.

Their replacements will be the ultra-compact 29 mm x 29 mm cameras as well as the approx. 35 mm x 35 mm format, supported by the latest generation of smaller, high-resolution CMOS sensors.

Customers Benefit From The Compact Housing Sizes:

  • A small camera footprint within systems cuts weight and thus increases the speed of applications. The lighter the robot arm, for example, the faster and more flexibly it can move.
  • Small camera formats also free up more space. This can be used to shrink the system or for easier physical access to the cameras as needed.
  • Small-format cameras rely on the cost benefits inherent to smaller sensors. Because they require more silicon, sensors with large sensor surfaces are significantly more expensive than small sensors.
  • Remarkable technological progress in industrial machine vision is really being driving in the small, compact sensor formats, and in particular in modern CMOS sensors.
  • Larger camera applications, typically CCD based, continue to perform their tasks in specific highly complex areas, but small-format sensors and cameras are primed to assume the majority of machine vision responsibilities going forward.

Do You Already Know about Our Basler Original Equipment?

The accessories market for machine vision cameras is broad and deep. Basler offers products specially developed for our cameras, meaning camera and lens harmonize perfectly with one another. The products are produced exclusively for us and are available only from Basler. All products with the Basler Original Equipment seal allow top performance when combined with Basler cameras.

Basler Lenses - Basler Original Equipment features high-resolution lenses conceived for sensors of up to 1/2" and very small pixels; this makes them the perfect match for Basler's ace, dart and pulse cameras. For our customers, this custom design means perfect interplay between camera and lens.

Power-I/O PLC+ Cable - Alongside the Basler Lenses, we offer our Power I/O PLC+ cable as Basler Original Equipmentfor use with a PLC. The cables reduce the signal level for the logical 0 from PLC level (<8.4V) to TTL level (<1.4V), optimizing it for use with programmable logic controller (PLC).

This cable provides clear transmission of the I/O signal and better camera performance by eliminating a variety of disruptions. This in turn ensures that our cameras deliver top performance for you even in critical industrial environments.

GP-I/O and Opto-I/O Cable - Basler ace cameras with USB 3.0 interface come equipped with two different types of digital I/Os: The opto-coupled I/Os are robust and largely impervious to disruptions. The direct-coupled GP-I/O (General purpose input/output) pin is very fast and is used with a 5 Volt (TTL) current. To allow for safe, trouble-free use of the I/Os, Basler offers two cables for isolated I/O usage on the ace USB 3.0 model: One for use with opto-coupled I/Os and one for the GP-I/Os.

(Power) I/O Cable - Our twisted (Power) I/O cables are available in various lengths and plug types. Depending on the camera, the cables come with a Hirose 6, Hirose 12 or M5 4-pin plug. The cables can deliver power and/or control impulses. The Basler Original Equipment also includes power supply units, an I/O board for simple control of the I/Os on the Basler dart, accessories for the Basler Lenses and tripod mounts for various cameras.

Condition monitoring & Hot Spot Detection

What is condition monitoring & hot spot detection?

Condition monitoring is a process of continuous observation and inspection of industrial installations. Inside these installations, you typically want to monitor the operational parameters, like temperature or vibration, of different components, equipment and machinery.

Thermography is a very important part of this process. This allows you to detect and analyse hot spots inside the process. A quick detection of these potential thermal anomalies prevent any premature failure of your installation.
What is condition monitoring & hot spot detection used for?

Condition monitoring is a major part of the general predictive maintenance program. By monitoring the critical elements in the process, you:
  • avoid any unplanned production stop
  • can effectively plan maintenance activities
  • increase life time of the different components in the production chain
  • comply with insurance company requirements
What features are needed?
  • Easy connectivity - We offer several different interfaces for an easy integration and maintenance into your system
  • Trigger interface with low jitter - A trigger interface with low jitter is a necessity for high speed applications to synchronize the camera
  • Rugged and small cameras - The ruggedness and size of our infrared cameras are important features for an imaging system. The smaller the camera, the easier it is to integrate. Rugged cameras withstand harsh environmental conditions
  • High radiometric accuracy - We typically guarantee +/- 2 °C or 2% (whichever is the highest) for uncooled cameras, and +/-1 °C or 1% (whichever is the highest) for cooled cameras depending on the ambient conditions
  • Windowing - Windowing the camera leads to higher framerates and therefore increased throughput
What do we offer?

For condition monitoring and hot spot detection Xenics offers various solutions depending on the operating environment of the system. The Gobi camera family is perfectly suited for primarily clean industrial environments as it comes in an IP45 enclosure. For more harsh and dusty environments our Serval camera family offers best radiometric performance in a ruggedized, IP67 certified, housing. In both camera families we offer high and low imaging resolution such that an optimized choice can be made for cost versus performance.
For very hot industrial processes, above 300°C, such as the inspection of furnaces, glass production, the steel industry or for molding processes, we also offer SWIR thermography on our Cheetah-640CL SWIR camera.
