Product Description:

The motor variant 8MSA3S.E3-I6 comes with an integrated encoder design. Its absolute multi-turn encoder records multi‑revolution positions, thus preventing reference loss after power cycles. A communication interface synchronous serial interface (SSI) enables synchronized data transfer to optimize feedback timing. Turns 4096 (12 bits) deliver an extensive counting range which supports high‑precision motion tracking.

This three-phase module offers 8192 steps/turn (13-bits) resolution per turn that provides fine angular granularity and enhances positional accuracy. A total resolution of 25-bits offers a broad numerical span, eliminating counting ambiguities over multiple revolutions. Supply voltage measures 4.75 – 30 VDC adapts to varied control architectures that simplifies power integration. Consumption of 110 mA current minimizes operational demand on power supplies; thereby reduces heat generation in tight enclosures. Operating at temperatures between -40°C to +85°C tolerates extreme ambient conditions only to sustain reliable operation in crucial environments. A shaft diameter of 6 mm matches common drive couplings which maintain secure mechanical linkage. Mechanical speed (max) of 10,000 RPM accommodates high‑speed shafts which preserve signal integrity during fast rotation.

IP65 safety standard seals internal electronics and a connection type M23 connector, 12-pin allows robust docking, preventing a signal interruption under vibration. The Binary or Gray selectable output code offers format flexibility which aligns with diverse control protocols. Aluminum housing provides corrosion resistance which extends service life in industrial settings. This B & R’s 8MSA3S.E3-I6 motor integrates design symmetry which eases panel layout. With its maximum shaft loading axial of 40 N, it withstands end‑force stresses and preserves bearing life Also, its radial 110 N resists side‑load pressure which protects encoder alignment under off‑axis forces.
