Like new Sony Magnescale SJ700A-080 scale with 3m / 9' cable and connector. 
Overall length 36.25" Max travel 32". Resolution .0002"
Completely tested and works great.
Will plug directly into a LH70 or LH71 display.
If requested I can change cables & reading head to plug directly into the LH51 / 52 displays.
I am a retired Sony tech. Please email me with any related questions.
