Item # DR28R2.5B03-P2AKL, 28 mm Rod Type Compact Electric Cylinder

28 mm frame size with a 30 mm stroke indicates a compact rod-type configuration for short linear movement, while the 2.5 mm lead and Precision Ball Screw point to motion focused on fine positioning rather than high travel per revolution. The guide, mount, electromagnetic brake, adjusting knob and ball screw cover are all listed as Not Equipped, so external mechanics, load support, holding strategy and protection need to be checked at the machine-design level rather than assumed from the actuator itself.

Max. vertical transportable mass is 2 kg, and max. horizontal transportable mass is 4 kg, so orientation directly affects allowable load. Max. speed is 100 mm/s, with max. thrust force 20 N and max. holding force 20 N; these values should be matched to the required push force and static holding requirement without relying on an integrated electromagnetic brake, because Electromagnetic Brake is specified as Not Equipped.

Repetitive positioning accuracy is ±0.003 mm, lost motion is 0.02 mm max., and minimum travel amount is 0.0125 mm, so the specification separates repeatability, reversal play and commanded increment; all three are relevant when motion changes direction or when small step moves are required. Electrical data are 1.5 A/phase, 1.77 VDC, 1.18 Ω/phase and 0.76±20% mH/phase, with an ambient range of 32ºF ~ 104ºF (0ºC ~ 40ºC) and humidity 85% or less, noncondensing.
