BEI Encoders BEI encoders are among the highest quality absolute and incremental rotary encoders and motion control components available today. We manufacture rugged, reliable, rotary position sensors and signal conditioning electronics used for demanding industrial applications such as: factory automation, motor feedback, robotics, web process control and instrumentation.

New Large Bore, Rugged, Hollow Shaft Encoder

BEI’s newest and largest-bore hollow shaft encoder is ideal for large motor feedback applications. The HS45 accepts motor shafts up to 1 5/8 inches in diameter (1 - 7/8 inches optional) and provides data for position and velocity control. This model incorporates the precise feedback capabilities of an optical encoder with an easily mounted configuration to larger motors. There is no need to step down or alter most large motor shafts.

The HS45 encoder provides an option for dual electrically isolated outputs. Should one set of outputs sustain electrical damage, a quick change of the connection enables you to get back up and running quickly. Alternatively, the dual output can also be utilized to feed two different controllers from a single encoder. This ensures speed and/or position synchronization without the cost of an additional encoder.
