Notes:
The sensor contains an IR viewing target with absorption bands from 400 to 640nm
and 800 to 1700nm that can be removed by carefully levering in the side hole with a
small screw driver.
The sensors can be equipped with fiber adapters from the S120 series.
(Order Codes: S120-FC, S120-SMA, S120-SC)
For use with metric posts insert the 8-32 to M4 adapter.
