Heidenhain ECM 2400 encoder
Heidenhain’s ECM 2400 encoder is a magnetic ring encoder with functional safety (FS) for machine tools needing contamination-resistant encoders for machine feedback.
This absolute modular magnetic angle encoder is designed for machine tool applications that require a sturdy encoder with medium accuracy. The ECM 2400 is suitable for applications with high rotational speeds, angular accelerations and limited space due to the complete system’s low overall height.
The company says the encoder works particularly well on 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 safety-oriented application (mechanical fault exclusion), a sturdy angle encoder, large inside diameter, lower position accuracy than an optical measurement system, and 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 (as per EN 61508) and with Performance Level “d” (as per EN ISO 13849). The fault exclusion that is implemented in its design has been tested and is ensured under the specified operating conditions. Existing non-FS interfaces for ECM 2400 encoders includes Fanuc05 and Mit03-4. All of these encoders have an IP67 rating.
