Linear position sensors convert the linear displacement of connected machinery into an electrical signal proportional to the object's displacement. Models are available in many sensing technologies, mechanical operation styles, mounting configurations, and stroke lengths.

Linear Position Sensors
Category Selection
Linear position sensors convert the linear displacement of an object into a proportional electrical signal. They are available in many mechanical styles and mounting configurations.
- Linear potentiometers use resistance between the wiper terminal and end terminals to provide a distance measurement; they typically require a signal conditioner or a 10VDC supply to provide an analog signal for a PLC
- Inductive linear transducers use inductive, non-contact technology to convert linear displacement to a 0 to 10 VDC or 4 to 20 mA analog signal
- Magnetostrictive sensors employ a magnet traveling along a rigid linear housing to provide linear position feedback via 0 to 10 VDC or 4 to 20 mA analog outputs
- Draw wire encoders measure displacement with an extendable cable. Models with quadrature pulse output, 0 to 10 VDC or 4 to 20 mA analog outputs are available.
- Encoder measuring wheels ride directly on a product or conveyer belt to measure distance/length or provide speed control feedback. Quadrature pulse output signals of 250PPR or 1250PPR are provided.
Linear Position Sensors Overview
Fixed Slide
Newest Additions!
- ProSense LSR-33P series fixed-slide linear potentiometers
Fixed-slide linear position sensors provide a fixed, threaded rod process connection and are available in a variety of housing styles, ranging from compact round designs to robust rectangular options suitable for applications with heavy vibration. Potentiometer and inductive technologies are available.
Rodless Slide
Newest Additions!
- ProSense LSRS-33P series rodless-slide linear potentiometers
Rodless-slide linear position sensors feature a cursor that moves along the entire sensor length, providing minimum installation length for applications where space is at a premium, such as plastic injection presses. Potentiometer and magnetostrictive technologies are available.
Spring Loaded Slide
Newest Additions!
- ProSense LSSR-33P series spring-loaded-slide linear potentiometers
Spring-loaded-slide linear position sensors feature a push-in style slide actuator with ball tip to measure distance when pressed, ideal for applications where the sensing element cannot be attached to the object whose position is being measured. Potentiometer and inductive technologies are available.
Pivoting Slide
Newest Additions!
- ProSense LCR-38P and LCR-18P series pivoting-slide linear potentiometers
Pivoting-slide linear position sensors use a rod eye mounting system with a cylindrical body that allows free movement of the transducer axle, adding versatility to their application use. Potentiometer and inductive technologies are available.
Draw Wire
New!
Draw wire linear measurement devices use a steel cable wrapped on a spring-loaded reel to measure distance. The reel is connected to a rotary encoder or potentiometer that can provide very accurate feedback of how far the steel cable has been extended.
Typical applications include linear measuring and vertical lift or cylinder stroke measurement.
Encoder Linear Measuring Systems
New!
Encoder linear measuring systems provide a spring-loaded, lever mount for a dual-shaft encoder with rubberized wheels attached to both shafts. The wheels ride directly on a product or conveyer belt to measure distance, length or provide speed control feedback. These are often used for cut-to-length and positioning applications.
