Festo
549409
Stepper motor EMMS-ST-57-S-SE
The Festo 549409 is an industrial component operating on a 48 V nominal DC voltage with a nominal motor current of 5 A, featuring a 1.8 deg stepper angle at a full step with a ±5% tolerance. This unit incorporates an optical encoder rotor position sensor, a Class B insulation protection class, an IP54 protection class, and a CE symbol according to the EU-EMV guideline alongside C-Tick authorization. It delivers a motor holding torque of 0.8 Nm, a brake holding torque of 0.4 Nm, a rotor mass moment of inertia of 0.29 kgcm2, and an overall mass moment of inertia at power take-off of 0.29 kgcm2, supporting a permissible axial shaft load of 10 N and a permissible radial shaft load of 52 N across an ambient temperature range of -10 to 50 °C, a storage temperature range of -20 to 70 °C, and a relative air humidity of 45 to 80%, all within a 970 g product weight equipped with a plug electrical 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.
