Description
The THI40 continues the new economical target
line of Pepperl+Fuchs. With a small outside
diameter of 40 mm, the unit is ideal for use in
industrial areas where very little space is available.
The technology of the rotary encoder is adapted to
the new requirements of the rotary encoder market.
Innovative fast technology with Opto-ASIC forms
the central basis of the device. The rotary encoder
is available with a pulse count of up to 1024 pulses
per revolution.
