RKLC20-S Incremental encoder system A-6663-0020

RKLC20-S is a narrow, low profile stainless steel tape scale featuring 20 µm pitch incremental graduations and IN-TRAC customer selectable reference marks

RKLC is a robust, 6 mm wide stainless steel encoder tape scale with a thickness of 0.15 mm. This allows the scale, when rigidly fixed to a machine axis, to become ‘mastered’ to the machine substrate, matching its thermal expansion coefficient and behaviour. Differential movement between the scale and the machine is thus minimised, improving the metrological performance that can be achieved with simple thermal system compensation.

What is RKLC20-S scale?

RKLC20-S is a narrow, low profile stainless steel tape scale featuring 20 µm pitch incremental graduations and IN-TRAC customer selectable reference marks. It is accurate to ±5 µm/m and available in lengths up to 20 metres (> 20 m on request). The RKLC20-S is mastered to the machine substrate giving improved metrological performance when the scale ends are rigidly fixed to the substrate.

The flexible RKLC20-S scale is also suitable for partial arc measurement where the small cross-sectional area allows it to be wrapped around a drum, shaft or arc with a minimum radius of 30 mm.
