Absolute (absolute value) non-contact magnetic linear encoder
Linear encoder scale system
[Sample loan available!] Standard set of absolute type with a compact head of 65mm width, resolution 0.01mm.
The "SA-200 System" is an absolute linear encoder system that employs a compact dedicated head. It comes as a set with a dedicated scale measuring 65mm in width, 20mm in height, and 25mm in depth. The detection distance of the head can achieve 0.3 to 1.6mm when the material of the mounting base is magnetic. Because it uses absolute detection, it can be re-measured without returning to the origin after power is restored. 【Features】 ■ It is a non-contact absolute scale system that allows for a large distance between the scale and the head. ■ Measurements are unaffected by dust and debris due to magnetic detection. ■ The system is available with varying detection distances and resolutions. *Sample loans available *For more details, please contact us or download the PDF materials.

Magnetic Scale "SAS-200" The "SAS-200" features a rubber magnet with an absolute code that is magnetized and adhered to a stainless steel base. The scale length can be manufactured from a minimum of 200mm to a maximum of 2,000mm. The total length specification will be 200+(8n)mm, where n is an integer.
-
Magnetic Detection Head 'SAE-200' The 'SAE-200-B□' can read the absolute code of the scale and measure absolute values up to a maximum length of 1,935mm. The output interface supports RS-422 serial communication, and the transmission speed can be specified at the time of order by the last character "□" of the model number*. The resolution achieves 0.01mm, and it is possible to set the origin at any position on the scale.
