Heidenhain Magnetic Encoder Ring

Heidenhain introduces the ECM 2400 encoder, an absolute modular magnetic angle encoder that is designed to resist contamination and offer functional safety (FS) for machine feedback. The ECM 2400 is suitable for applications with high rotational speeds and angular accelerations. It’s low overall height makes it suitable for operations that have limited space, according to the company.

The ECM 2400 is suitable for B-axis lathes with motorized milling spindles or on the A and C axes of milling machines where a large, hollow shaft encoder is necessary. In general, it is suitable on all rotary axes that require the following attributes:

  • Safety-oriented application (mechanical fault exclusion)
  • Sturdy angle encoder
  • Large inside diameter
  • Lower position accuracy than an optical measurement system
  • Dynamic positioning accuracy (simultaneous multi-axis machining)

The ECM 2400 encoders are available with EnDat 2.2 interface. In conjunction with a safe control, they can be used as single-encoder systems in applications with control category SIL 2 (per EN 61508) and with Performance Level “d” (per EN ISO 13849). Its fault exclusion has been tested and is ensured under the specified operating conditions, according to Heidenhain. Existing non-FS interfaces for ECM 2400 encoders include FANUC 05 and Mit03-4. All of these encoders have an IP67 rating.


  • Applying Turn-Milling

    Combining a rotating tool with rotating work produces a machining operation that is distinct from standard turning or milling.

  • Why Y-Axis For Turn/Mill Machines?

    Live tooling on turning centers greatly expands multiple processing capability. With the addition of Y-axis, turning and machining process integration takes a significant step further. Here's how the technology works.

  • More Efficient Turbine Blade Milling
