3 in One Absolute encoder.
The requirement was to control the positioning of 3 collimator beams in a medical instrument. A major obstacle for the use of off-the-shelf solutions is the lack of space.
The customer requested a customized solution aiming at use of the lowest volume possible. Another requirement was not to use cabling to the moving arms.
The chosen implementation was developed: A 3-in-1 encoder, making use of passive read heads, and where 3 such read heads “share” a single transceiver scale system.
The 3 encoder solution required a small foot-print of 42 x 33 mm and a height of 16 mm. The proposed solution performance was tailored to the system requirements in order to provide the best cost/performance ratio.
The product is in full production since 2005.
