When motor encoder accuracy isn’t enough — but space is limited.
Our integrated measuring system delivers the precision you need, built directly into the guideway. One system. Zero compromises.
A pick-and-place unit in semiconductor assembly requires high-speed positioning within extremely space‑constrained machine designs — maximum performance with minimal footprint.

Compact analytical devices demand repeatable sub-micron positioning in the
smallest possible installation space — reliably, cycle after cycle.

Precision metrology equipment often operates in tightly packed setups.
Combining guiding and measuring in one compact unit ensures highest accuracy without
increasing the system footprint.

MINISAM is an All-in-One solution and the smallest integrable measuring system for miniature guides. It is a Plug and Play system that is ready for use without the need for additional settings or adjustments.
The SAM measuring system offers five interface options: BiSS/SSI, ABZ, UVW, SPI, and analog Sin/Cos interfaces.
The SAM measuring system operates optically. A central illumination LED sensor and two lensless optical encoder windows detect the absolute position using a Pseudo-Random Code (PRC). Additionally, an incremental encoder is used for the interpolation of high-resolution position data.
The SAM measuring system can be integrated into all MINIRAIL sizes and carriage types, ranging from size 5 to 42.
The SAM system can either be connected via a flexprint to a connection board or directly to a controller. The flexprint can be customized by the customer. Depending on the application, the customer can decide whether a connection board is needed or not.
