Festo
1704790
Servomotor EMMS-AS-70-S-HV-RRB-S1
Engineered with 4 pole pairs and a star inside winding switch configuration, this Festo industrial component operates at a nominal DC voltage of 565 V with a standstill torque of 1.62 Nm, a nominal torque of 1.28 Nm, and a peak torque of 5.17 Nm. The unit features IP65 protection, insulation class F, continuous S1 rating according to EN 60034-1, and PTC resistor temperature monitoring while conforming to IEC 60034 standards, RoHS materials notes, and CRC 2 moderate corrosion stress resistance. It holds RCM Mark and c UL us Recognized authorizations, carries the CE symbol per EU-EMV and low voltage guidelines, and operates within ambient temperatures of -40 to 40 °C, storage temperatures of -20 to 60 °C, and 0 to 90% relative air humidity through an electrical plug connector system.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
