SIL 3 certified: Multiturn absolute encoder with hollow shaft

The multiturn absolute encoder AM…H 41 is deployed in particularly safety-critical projects; SIL 3/PL e certification guarantees they fulfill the highest safety requirements.
The AM… 41 with a hollow shaft is certified in accordance with the international standard covering functional safety of electrical, electronic and programmable electronic safety-related systems EN 61508/EN 13849. The diameter of the hollow shaft including keyway for the versions PROFIsafe via PROFIBUS-DP or PROFIsafe via PROFINET IO is 20 millimeters. The resolution of singleturn is 13 bit (steps per revolution: 8192) and multiturn 15 Bit (number of rotations: 32768). A second shaft end is available on request.
