The smallest SIL2 / PLd and SIL3 / PLe absolute safety encoders

See TR Electronic at MachineBuilding.Live, 4 October 2023, on stand 61

Safety encoders from TR Electronic are a completely redundant CAT4 design with two fully independent multi-turn encoders in the size of a single standard size 58mm, 75mm or 115mm body. The choice of either SIL2/PLd or SIL3/PLe means you can select the exact safety performance level for your needs.

Available in solid shaft, hollow shaft and blind hollow shaft, the encoders are said to be ideal for both new applications or for upgrading existing applications to functional safety. There is even an optional secondary output available in the form of either an incremental 5v/TTL, HTL, Sin/Cos or SSI output.

Interfaces include PROFIBUS / PROFINET with PROFIsafe, FSoE Safety over EtherCAT, EtherNet/IP - CIP Safety, Safety over POWERLINK, and CANopen Safety.

There is additional physical protection in the form of sea water resistant housings and even a 316L Stainless Steel housing for harsher environments and wash down areas.

For linear measurement, there are wire rope pull units with lengths up to 60 metres.

For explosive atmospheres, TR Electronic can offer SIL3/PLe safety in both Zone 1/21 and Zone 2/22 ATEX rated encoder housings and can even offer ATEX wire rope pull units.

The free fitting, operating and commissioning manuals, together with EPLAN marcos, SISTEMA Library files and 3D STEP files, allow for easy CAD design and fast setup.

Step by step commissioning guides are available for Siemens SIMATIC S7, ABB AC500-S, Beckhoff TwinCAT System Manager, Schneider M580 (BME P58), Rockwell (GuardLogix 5370) and B&R X20 CPU.

All TR-Electronic safety encoders are TÜV Functional Safety Type Approved and UKCA, CE and UL Compliant. CIP Safety interface encoders are additionally ODVA conformant.
