FLUX GmbH Launches IP67-Rated IND-ROT-G Rotary Encoder

FLUX GmbH has expanded its high-precision motion control portfolio with the launch of the IND-ROT-G, a guarded, IP67-rated addition to its IND-ROT inductive rotary encoder series. Designed to deliver true absolute position feedback in a highly compact, frameless format, the new series provides robust environmental protection for systems operating in dusty, wet, and heavily contaminated conditions without requiring an increase in the encoder's physical footprint.

Available in four sizes ranging from 55 mm to 96 mm in outer diameter, the IND-ROT-G achieves up to 21-bit resolution. The unit is engineered to perform reliably despite high shock, heavy vibration, and extreme temperature fluctuations. With stators weighing as little as 22 grams, the design adds critical ingress protection without adding meaningful weight to the host system. The encoder requires no calibration due to its plug-and-play installation and supports standard industrial communication interfaces, including BiSS-C, SSI, and incremental A/B/Z. This makes it an ideal feedback solution for demanding, size-restricted applications such as unmanned aerial vehicles (UAVs), stabilized camera gimbals, medical robotics, and industrial automation equipment.

Additional Context
This section provides technological and market background not explicitly detailed in the original release.

Inductive encoders operate using electromagnetic induction, making them inherently resilient to environmental contaminants like oil, dust, and moisture that can easily disrupt optical or magnetic encoders. While traditional frameless inductive encoders excel in compact spaces, exposing their internal printed circuit board (PCB) coils to extreme moisture or particulate buildup can still cause long-term reliability issues or signal drift.

By achieving an IP67 rating in a guarded design, the IND-ROT-G allows engineers to deploy the sensor directly in washdown environments or outdoor robotics without needing to design bulky, custom-sealed housings around the robotic joint. Furthermore, the 21-bit resolution translates to over two million unique positions per revolution (2^21 = 2,097,152). This ultra-precise positional data is critical for advanced automation, such as minimizing jitter in long-range optical gimbals or ensuring sub-millimeter accuracy in surgical robotic arms.
