For those needing contamination-resistant encoders with functional safety (FS) for machine feedback, HEIDENHAIN introduces an absolute modular magnetic angle encoder. This new ECM 2400 encoder supplements HEIDENHAIN’s portfolio of absolute angle encoders and 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 it low overall height of the complete system.
The ECM 2400 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 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 (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 and can be ordered now.

- electrochemical machining ( ECM)
electrochemical machining ( ECM)
Operation in which electrical current flows between a workpiece and conductive tool through an electrolyte. Initiates a chemical reaction that dissolves metal from the workpiece at a controlled rate. Unlike with traditional cutting methods, workpiece hardness is not a factor, making ECM suitable for difficult-to-machine materials. Takes such forms as electrochemical grinding, electrochemical honing and electrochemical turning.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
