Description
Linear encoder with small reader head, air intake and connector at both ends, with threaded head for different mounting options without the need for nuts.
Especially indicated for high standard environments in terms of speed and vibration. Their special design of the securing points of the linear encoder (TDMS™), drastically reduces the effects and ensures the accuracy and repeatability of the encoders.
