HEIDENHAIN Offers Safety-oriented Rotary Encoders In a Small Footprint

SCHAUMBURG, IL – (December 2009) – Opening up the market for innovations in the automation, medicine and electronics equipment industries, HEIDENHAIN Corporation presents a new generation of rotary encoders with IP 64 protection, absolute position-value formation and functional safety, all within a 35 mm diameter housing size.  These small rotary encoders are known as HEIDENHAIN’s 1000 Series and designed to be especially useful as single-encoder measurement feedback systems in safety-oriented applications.

HEIDENHAIN’s safety-oriented position encoders with functional safety provide two independently formed position values via a serial EnDat interface.  They are certified according to the EN ISO 13849, EN 61508 and EN 954-1 standard for performance level d, safety integrity level 2 and category 3, respectively.  The EnDat 2.2 version of these new absolute rotary encoders with 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.

Eight new rotary encoders round out HEIDENHAIN’s 1000 Series including ECN 1013, ECN 1025, EQN 1025, EQN 1035, ROC 1013, ROC 1025, ROQ 1025 and ROQ 1035.
