Posital unveiled a fully functional prototype of miniature multi-turn kit encoder for integrated motor feedback. With a diameter of 22 millimetres and a height of 23 mm. It features a self-powered rotation counter.
¡°Our new mini kits build on the success of the kit (or modular) encoders that we introduced in 2016,¡± said Jim Stevens, Product Manager Kit Encoders, 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.
They cover a multi-turn measurement range and provide digital output. They are rugged and resistant to contamination by oil, dust or moisture; offering 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 is straightforward and can be done under normal factory conditions.
¡°In the coming months, we¡¯ll give our 22mm kit the finishing touch in a detailed beta testing program involving well-known motor manufacturers,¡± said Stevens. Full product roll-out will take place after evaluation of these test runs and is expected in mid-2020. 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,¡± said Stevens.
