Introducing the World’s Smallest Multi-Turn Absolute Kit Encoders

Miniaturized device features accuracy, robustness and a zero-maintenance rotation counter – all in a 22 mm diameter package

Size matters, and in the world of industrial automation, providing exceptional performance in a highly compact package can be an enormous advantage. With this in mind, encoder manufacturer POSITAL has unveiled a fully functional prototype of their new miniature multi-turn kit encoder for integrated motor feedback. With a diameter of only 22 mm and a height of 23 mm (0.87”/0.9”), the new device is the world’s smallest multi-turn kit. It features a self-powered rotation counter that does away with the need for backup batteries or complex gear systems. POSITAL’s extremely trim 22 mm magnetic Kit Encoders are designed for builders of servomotors, feedback-controlled stepper motors, microdrives, miniature robots and other machines where high-precision position feedback is required and space is at a premium.

Posital Miniature Absolute Kit Encoder

Like their ‘big brothers’, the new 22 mm kits are reliable, accurate and simple to install. Unlike resolvers, they cover a multi-turn measurement range and provide digital output. Compared to optical kits, they are more rugged and more resistant to contamination by oil, dust or moisture. They offer 17-bit electronic resolution and a multi-turn measurement range of up to 32 bits. Vendor-neutral SSI and BiSS C interfaces are supported. Installation of the 22 mm kits is very straightforward and can be done under normal factory conditions. Integrated self-calibration simplifies commissioning. The combination of robust magnetics, high operational reliability (with an integrated temperature sensor for diagnostics), multi-turn functionality and maintenance-free operation all help to reduce the cost of ownership.

POSITAL Sensors – Precision Feedback for Collaborative Robots

Encoders measure rotation and return a digital signal that reports the angle of rotation (absolute encoders) or rate of motion (incremental encoders) to the control system. The ‘right’ encoders for cobots need to be accurate, reliable, and compact, with excellent dynamic response characteristics. They also need to be reasonably priced. POSITAL-FRABA has responded to this challenge by developing new sensing technologies – such as magnetic and capacitive rotary encoders – that provide cobot manufacturers vital feedback for closed-loop control systems. In order to ensure that these devices meet the needs of cobot builders, POSITAL-FRABA offers products with a wide range of performance characteristics, communications interfaces and physical configurations.

 

A very exciting development in the area of robotics is the development and growing popularity of so-called collaborative robots, or “cobots”. Cobots, in contrast to traditional industrial robots, are designed to interact with human workers in a shared workspace. They are typically smaller and less powerful than traditional factory robots and are equipped with a variety of proximity sensors, load sensors and other features designed to avoid dangerous collisions between the robots and the people working around them. This focus on safety means that cobots are easier to deploy in a normal factory setting, since they don’t required special fenced off operating areas. Cobots have been used to perform repetitive tasks in light assembly, packaging, materials handling and medical laboratories. Cobots have also been used to help workers avoid direct contact with environments not conducive to direct human interaction, such as high temperature environments, chemically aggressive reagents and toxic pathogens.

Enabling Technologies for the Cobot Revolution
Many cobots are designed to mimic a human arm, with flexible “shoulder”, “elbow” and “wrist” joints. Accurate measurement of the rotary position of these joints is central to enabling the cobots’ control system to keep track of the spatial orientation of all of its moving parts. This is typically provided through rotary encoders mounted in each of the device’s joints.

New Stainless Steel Rotary Sensors by POSITAL – FRABA

POSITAL Stainless Steel Rotary Sensors – The Right Flavor for the Food and Beverage Industries

POSITAL Stainless Steel Rotary Sensors – The Right Flavor for the Food and Beverage Industries

POSITAL’s IXARC rotary sensors are available with V4A-rated stainless steel housings and IP69K-level environmental seals.  These rugged and versatile encoders are ideal for applications in the food and beverage industries since they can stand up to highly aggressive cleaning procedures and still deliver the reliability and measurement performance demanded by motion control systems.

The stainless steel housings are also available in explosion-proof (ATEX-rated) designs that can operate safely in environments with potentially dangerous levels of explosive dust or gases.  These models are ideal for grain or flour-handling facilities.

POSITAL encoders are available with a wide variety of output interfaces, ranging from analog to industrial Ethernet. The analog-output devices (also known as programmable potentiometers) are designed to function as a ‘drop-in’ replacement for conventional multi-turn potentiometers in simple control systems.  Because they are based on a magnetic sensor technology that requires no physical contact between measuring components, POSITAL encoders are immune from the wear and corrosion that can degrade the accuracy of conventional resistance-type pots.  Programmability means that they can be readily configured to meet each application’s exact requirements.

Industrial Ethernet connectivity, such as EtherNet/IP, provides a solid base for complex multi-sensor, multi-controller systems. POSITAL EtherNet/IP connected rotary sensors are ODVA-approved and are available in single or multi-turn versions with 16-bit resolution (65,536 steps/turn).
