World’s Smallest Multiturn Absolute Kit Encoders

New 22 mm Mini Multiturn Kit Encoder for Integrated Motor Feedback

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.

Reliable, Accurate and Simple to Install

  • No Battery, No Gear – No Maintenance
  • Electrical Resolution Up To 17 bits, Multiturn Range Up To 32 bits
  • Robust Performance, High Accuracy And Easy installation with Optional Self Callibration
  • Available in BiSS C and SSI interfaces with a Preset Function
  • Integrated Temperature Sensor for Diagnostics

“Our new mini kits build on the success of the kit (or modular) encoders that we introduced in 2016”, says Jim Stevens, Product Manager Kit Encoders at POSITAL North America. “By careful redesign and the introduction of smaller electronic component, we have been able to reduce the diameter of these devices from 36 mm to 22 mm.” A key achievement has been the miniaturization of the Wiegand energy harvesting system that powers the rotation counter. This system is a very important part of POSITAL’s competitive positioning since it ensures reliable absolute multi-turn position measurement without any need for high-maintenance batteries or gear systems.

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.

“Special shaft versions of the 22 mm kits with integrated bearings, which can provide additional applications, are also being planned. “With miniaturization marking a major trend in global automation, we see great potential for our new mini kits,” concludes Stevens.

Access Management for Your Plant and Machinery

With PILZ’s “Identification and Access Management” portfolio, they offer you a comprehensive range of products, solutions and software for the implementation of safety as well as security tasks. Below you’ll discover more about potential applications, from simple authentication to complex access permissions, and access management through to safe operating mode selection, maintenance safeguarding and safeguarding of data and networks. Experience safety and security in one system!

This solution ensures that a machine cannot resume operation while people are still in the danger zone. The maintenance safeguarding system “key-in-pocket” is designed for machines with danger zones, which are protected by a safety fence and which staff need to access – robot cells for example. In comparison with conventional lockout-tagout (LOTO) systems, maintenance safeguarding with the key-in-pocket solution is implemented via RFID keys with corresponding permissions and a safe list in the PILZ controllers. As a result, it provides a purely electronic restart protection and makes both mechanical interlocking devices and warning tags redundant.
