The Model LT25 linear cable transducer provides digital position and speed information in a durable, easy-to-install package. The LT25 cable transducer utilizes a flexible cable, a spring-loaded spool, and an incremental optical encoder to precisely measure linear position. Cable transducers are also known in the industry as cable-extension transducers, string potentiometers, draw wire sensors, draw wire transducers, yo yo pots, linear position string pots, string encoders.
The sturdy measuring cable (also referred to as the string or wire) is made of nylon coated stainless steel for ultimate strength with a measurement range up to 125 inches. The LT25's compact profile and IP66 rating makes this a perfect solution to a variety of industrial linear measurement challenges, whether involved in concrete cutting, controlling hydraulic cylinders, metal grinding, or having an awkward access area for measurement.
One of the greatest advantages the linear cable transducer offers is its simple and adaptable installation. Simply connect the wire to your moving equipment and secure the base to a fixed object. Hard to reach areas and worries about shaft misalignment are now not a problem, as the LT25's flexible designallows for versatile measurement setups with the same interface design as used for rotary axes.
This linear cable transducer unit is ideal for wet, dirty, or outdoor environments and applications where your measuring range travels over harsh environments.
Linear cable transducers are also referred to by such names as:
string pot or string potentiometer
cable-extension transducer
string encoder or cable encoder
draw wire sensor or draw wire transducer
yo yo sensor
Installing the LT25 Linear Cable Transducer
The LT25 Linear Cable Transducer installs in just a few simple steps:
Step One:
Mount the LT25 securely to a stable,
flat surface using the attached L-shaped mounting bracket with 1/4" (6mm) maximum diameter fastener.
Step Two: Attach the cable using the eyelet provided
(M4, #8 screw or /16" pin).
Tips to prevent damage to the measuring cable :
Make certain the cable path is clear of objects or sharp edges to prevent cable damage
Damage may occur if cable is released and allowed to retract with no tension
Cable should exit as straight as possible. A pulley may be used to redirect cable path
Flexible Installation Options
The LT25 allows for easy reorientation of the mounting bracket or encoder connector position. This gives users added flexibility in their installation.
How to Change the Mounting Bracket Position
Remove the four screws as shown with a PH-2 (Phillips) driver, reposition in 90° increments, and tighten screws to approximately 13in-lb.
How to Change the Encoder Connector Position
Remove the four cap screws on encoder flange (use a 5/32" hex driver), rotate encoder in 90° increments and tighten the screws to approximately 13in-lb.
