AMO Encoders Now Available for Functional Safety-rated Machines

Heidenhain Corp.

 Functional-Safety-rated (FS) contamination-resistant encoders for machine feedbackSCHAUMBURG, IL – For those needing Functional-Safety-rated (FS) contamination-resistant encoders for machine feedback, AMO - a HEIDENHAIN brand - introduces FS absolute angle and linear encoders. While Functional Safety-rated machines are a standard requirement in the European Union, machine manufacturers outside the EU are now seeing the benefit of including FS in their machines. With these encoders in use on FS-certified machines, a user can confidently operate in the area of this machinery knowing extra safety measures are in place for their benefit.

Possible FS-machine applications include robotic shuttles, pick-and-place machines, AGVs and both CNC & manual mills, lathes and grinders, among others. These FS AMO absolute encoders are available in the WMKA 2010 angle encoder and both the LMKA 2010 (non-guided) and LMKA 3010 (guided) linear encoders.

These AMO FS encoders are available with either EnDat 2.2 or DRIVE-CLiQ interfaces. In conjunction with a safe control, they can be used as single-encoder systems in applications with control category SIL 2 (as per EN 61508) and with performance level “d” (as per EN ISO 13849). (DRIVE-CLiQ is a registered trademark of SIEMENS AG.)

Existing non-FS interfaces for AMO encoders include Fanuc, SSI with 1Vpp, BiSS/C, Mitsubishi, and EnDat (without FS). All these AMO encoders have an IP67 rating and can be ordered now.
