Position and speed data for automation and drive technology

Position and speed data for automation and drive technology

The demands on sensors for position detection in automation and drive technology are increasing with the complexity and performance of the associated machines and systems. The high-resolution, non-contact absolute encoder MSA213K from Siko offers a solution for this. This provides the absolute position at any time (without referencing or buffer battery). With its high signal quality, the encoder is ideal for use in handling and assembly automation, machining systems, pick-and-place applications, PCB machining and always provides precise values for position and speed measurement in linear direct drives.

High resolution and absolute

The magnetic absolute linear encoder impresses with a high absolute resolution of 1 µm, ensuring precise position detection at all times. Absolute measurement is essential, especially in safety-relevant applications, when a change in position must be reliably detected even in a de-energised state. 

The realised repeat accuracy of ±1 µm enables reliable use in multi-axis applications or positioning systems in which precise control or detection of positions is required. This performance is achieved over a length of up to 16 metres. 

Numerous interfaces

To ensure that the MSA213K can be integrated as easily as possible, it is available with numerous absolute interfaces. Starting with the basic versions with SSI and BiSS C, the sensor is also available with IO-Link. In addition, a parallel incremental interface is available as a digital line driver or analogue 1 Vpp signal output. With this combination, absolute travel information is available at all times and precise commutation is possible even in dynamic operation. 

Mounting flexibility

The compact mounting dimensions and a large reading distance of up to 0.8 mm, together with the 270° swivelling connector, enable flexible integration into a wide range of applications. For easy installation and operation, the absolute encoder has a clearly visible function and status indicator LED that provides feedback on function and operating status.
