Specification No. 02115-001 Rev.08-11
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 object. No
need to worry about shaft misalignment. The sturdy measuring cable is
made of nylon coated stainless steel for ultimate strength, with a
measurement range up to 125 inches. This unit is ideal for wet, dirty or
outdoor environments and applications where your measuring range travels
over harsh environments.
