The LD660 Series rugged LVDT’s
are designed for use in wet or
challenging environments in
industrial control applications.
They are available with either
a ± 5 Vdc output with zero volts out
at center position or a 0 to 10 Vdc
with zero volts out at the extended
position. All models carry an IP68
environmental rating and utilize a
screw mount configuration for easier
installation. They are spring loaded
and include a ball tip and screw
mounting fixture.
