News from the Little Ones Absolute Rotary Encoders, Now with Functional Safety Even for the 35-mm Design

HEIDENHAIN has expanded its range of standard rotary encoders with 35-mm housing diameters, and will present a new generation of rotary encoders with IP 64 protection, absolute position-value formation and functional safety at SPS/IPC/DRIVES. This will open up a market for new applications in automation technology, medicine technology and the electronics industry.

The EnDat 22 version of the new absolute rotary encoders with purely serial data transfer offers a singleturn resolution of 23 bits, and a multiturn resolution of 12 bits. The supply voltage range is from 3.6 V to 14 V.

Safety-oriented position encoders with functional safety provide two independently formed position values via the serial bidirectional EnDat interface. They are certified according to the EN ISO 13849, EN 61508 and EN 954-1 standards for performance level d, safety integrity level 2 and category 3, respectively.
