LT25
Linear Cable Position Transducer

Model LT25 linear cable position transducer provides digital position and
speed information in a rugged, easy-to-install package. Simply connect the
cable to your moving equipment and secure the base to a fixed ob
need to worr
made of nylon coated stainless steel for ultimate strength, with a
measurement range up to 125 inches. This unit is ideal for wet, dirty o
outdoor environments and applications where your measuring range travels
over harsh environments.

The LT25 is available with the following certifications:
