Festo
1578603
Servomotor EMMS-AS-40-S-LS-TSB
The Festo 1578603 is an industrial component featuring a nominal DC operating voltage of 360 V, 4 pole pairs, a star inside winding switch type, a standstill torque of 0.16 Nm, a nominal torque of 0.14 Nm, and a peak torque of 0.5 Nm. It operates within an ambient temperature range of -10 to 40 °C, withstands storage temperatures from -20 to 60 °C, handles 0 to 90 % relative air humidity, and achieves an IP54 protection class with insulation class F and an S1 rating class according to EN 60034-1 while conforming to IEC 60034. Authorized by RCM Mark and c UL us - Recognized (OL), this unit complies with EU-EMV and low voltage guidelines, features a PTC resistor for temperature monitoring, a plug electrical connector system, and uses RoHS-conforming materials with a CRC 2 moderate corrosion resistance classification.
