With IP65 environmental rating and UL/CE certifications, J series includes 100–750 W power ratings as well as windings for various DC and AC voltages. All models have integrated brake options. While laser-welded, segmented stator pole construction allows for maximum copper fill, encapsulation method maximizes heat transfer. Inertia ranges from 0.00059–0.01373 oz-in./sec², and included incremental commutating optical encoders offer 10,000 counts per revolution.
