This document provides information on the general data, environmental conditions, features, mechanical data, and operating voltage of the BHG BHF optical incremental hollow shaft encoders.
The BHF/BHG series are optical incremental hollow‑shaft encoders with a 12 mm hollow or through‑hole shaft. They feature an optical sampling principle, up to 10 000 impulses per revolution, low mounting depth and various mounting accessories.
The document provides electrical parameters, mechanical data, torque ratings, environmental limits, wiring diagrams, connector pin assignments and ordering details for both the BHF (IP 42) and BHG (IP 65) variants. This manual is written in German.

The BHF encoder can run up to 12 000 rpm (IP 42).
Three supply options are provided: 5 VDC (05A), 4.5‑30 VDC (25W) and 10‑30 VDC (24K).
The encoders can deliver up to 40 000 steps per revolution when configured for 10 000 impulses.
