Lucas Ledex Optical Encoder Model SSO-0360-12HS-F6S-1

I bought from an auction 3 pcs. Lucas Ledex Optical Encoder Model
SSO-0360-12HS-F6S-1, they are brand new. Could I ask the assistance of
anyone from the group who is familiar with these encoders concerning the
technical datas or specs or probably the website which I could gather some
datas. Have tried searching but could not find any info. Thanks a lot.
