Festo
1704784
Servomotor EMMS-AS-70-SK-HV-RRB
The Festo 1704784 industrial component operates with a nominal DC voltage of 565 V, four pole pairs, a standstill torque of 1.62 Nm, and a nominal torque of 1.28 Nm via a star-inside winding switch. This part conforms to IEC 60034, features an insulation protection class of F, an IP54 protection class, and a DIN 6885 A 4 x 4 x 16 featherkey shaft design. It functions within an ambient temperature range of -40 to 40 °C, a storage temperature range of -20 to 60 °C, and 0 to 90 percent relative air humidity while utilizing a PTC resistor for temperature monitoring and a plug electrical connector system. The RoHS-compliant unit achieves a CRC corrosion resistance classification of 2, carries RCM and c UL us authorizations, and complies with CE EU-EMV and low voltage guidelines under EN 60034-1 S1 rating conditions.
