SICK SES/SEM70 motor feedback systems

Click2Contact

The SES/SEM70 motor feedback systems feature a hollow shaft diameter of 25 mm and are installed directly on the motor shaft — so there is no need for any strap connections or mechanical couplings. After installation, it is also possible to read out the position of the rotor using the PGT11-S programming device, providing a reliable way of identifying installation errors. The small design saves space and weight and is rugged and wear-free due to bearing-free technology. Sick is also working on another size featuring a hollow shaft diameter of 50 mm, plus a safety variant that is SIL2-certified.

The multiturn variant with a mechanical gear mechanism — eliminating the need for additional components such as external buffer batteries — can capture up to 4096 revolutions.

The SES/SEM70 motor feedback systems are suitable for use in torque motors and rotary tables, as well as in the diverse area of direct drives within robot applications, injection moulding machines, woodworking centres, semiconductor technology and handling systems.
