Functionally Safe Encoders from TR – A Safe Solution for Your Positioning Tasks

Many automation applications are subject to the highest safety requirements. By using SIL/PL-certified products, you can achieve maximum safety in shared workstations or environments where people and machines operate together. Our absolute multiturn encoders with SIL or PL certification (safety encoders) are available in 36 mm, 58 mm, and 75 mm sizes.  Common interfaces such as Dual SSI, PROFIsafe via PROFIBUS or PROFIsafe via PROFINET, Open-Safety via Powerlink, or FSoE via EtherCAT ensure optimal safety and precision. (Availability/configuration varies by size)

No separate modules are required for safe position output, and there is no need to program a separate safety module—it doesn’t get any simpler or more cost-effective than this.

36 mm size: CD_362+FS

Absolute safety has never been this compact.

Redundant sampling in single- and multiturn detection, combined with internal signal verification, ensures the same level of safety up to SIL3 / PLe as with “the big ones.”

CANopen Safety and IO-Link Safety, SSI+SSI, and SSI+INK (in development) are available directly from the encoder. Via an external converter box, PROFIsafe over PROFINET or PROFIBUS, CIPsafety over Ethernet/IP, Functional Safety over EtherCAT (FSoE), and OpenSafety over Ethernet Powerlink are feasible (in development).

Mechanically, the encoders are mounted via a solid shaft or a blind shaft (slotted hollow shaft).

58 mm size: CD_582+FS

The versatile workhorse among TR Electronic’s absolute encoders for safety-related applications.

The well-known safety-certified interfaces for automation applications are generated and output directly within the device—no converters, no separate evaluation modules. Solid shafts, blind-hole shafts, and through-hole shafts (up to 15 mm) connect the encoder to the customer’s mechanical system. Secondary interfaces such as incremental signals, SSI, and—newly—CANopen are available for the direct evaluation of a highly dynamic (non-safe) position signal for downstream controllers, secondary displays, and emergency control systems.

75 mm size: CD_752+FS

Our entry-level model in the field of safe absolute encoders, with which we revolutionized the market over 20 years ago.

Completely redesigned from a technological standpoint, the larger housing features through-shafts up to 20 mm. All interfaces of the CD_582 series are also available in the second generation of our “large” SIL encoder. And for our existing customers, fully compatible solutions are available for the seamless replacement of encoders that our application pioneers used in their systems, stage machinery, and production lines as far back as 20 years ago.

SIL3 / Ple-Certified Incremental Encoders

TR Electronic’s safety-oriented incremental encoders are designed for the reliable detection of speed, direction of rotation, or standstill. Certified up to SIL3, they enable the operating modes SLS, SOS, SSR, SDI, and SSM when used in conjunction with a suitable safety module.
