Festo
The Festo part number 8101539 is an electric cylinder with a toothed belt, integrated actuator, and a plain bearing-guide providing torsion protection for a size 45 unit with a 10 mm stroke and 0 mm stroke reserve. This component features an effective drive pinion diameter of 10.18 mm, a 2 mm toothed belt pitch, a 0.31 % toothed belt elongation, an M6 piston rod thread, and can be mounted in any position. Operational performance includes a maximum speed of 0.44 m/s, a maximum acceleration of 9 m/s², a repetition accuracy of ±0.05 mm, position sensing via motor encoder, and an absolute single-turn magnetic rotor position sensor. Integrated functions comprise a user interface, LED display, integrated end-position sensing, and temperature monitoring with an integrated precise CMOS temperature sensor with analog output that initiates a shutdown in the event of overtemperature, alongside configurable, non-galvanically isolated digital logic outputs.
