Product details

Overview

The 6-pole motor includes a holding brake and index pulse feedback, all in an IP41-rated flange-mount package.

The ILS1B852PB1F0 is in active production. It is CE marked and complies with IEC 61800-3 for EMC in the second environment. For current lead times and pricing, submit an RFQ — availability is generally stable for this generation of Lexium integrated drives.

Alternatives & selection

Compared to the BRS368H131ACA, the ILS1B852PB1F0 delivers higher holding torque (4 N.m) and finer resolution. The BRS368H131ACA runs at higher speeds and has a higher switching current.
