Heavy Duty Rotary Encoders

Heavy-duty rotary encoders are hollow-shaft incremental encoders built for monitoring speed and position in drive technology and motion control applications. Backed by rich industrial experience, these encoders are supplied to a wide clientele base and are sturdily constructed using best-quality materials under professional guidance and supervision. Heavy-duty incremental encoders from Baumer Hübner have become an industry standard over the years, thanks to their rugged construction adapted to demanding applications. They stand out for quality, durability, effectiveness, efficiency, reliability, and long functional life, offered at highly economical prices.

It is used for monitoring speed and position in drive technology and motion control applications, particularly in industrial environments that demand rugged, reliable performance.

They feature a solid aluminium housing with high vibration and shock resistance, extended IP66 protection with labyrinth or marine-grade sealing, and an operating temperature range of -40°C to +100°C (optionally down to -50°C).

Output signals are available in HTL (with power transistors) or TTL (RS-422), with supply voltage options of +5V or +9 to +26V using the internal regulator version.

Some models can operate in potentially hazardous environments, refer to the operating instructions for detailed information, as not all versions are UL approved for such use.

They include built-in protection against induced shaft currents, with an optional earthing brush available to divert currents generated by IGBT converters.

Yes. The twin encoder option (HOG 10 G) provides two separate encoder systems in one unit.
