Linear position sensors convert the linear displacement of connected machinery into an electrical signal proportional to the object's displacement. Models from Gefran and Alliance Sensors 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 with a variety of stroke lengths.
- 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
Linear Position Sensors Overview
Fixed Slide
Fixed slide potentiometer linear position sensors provide a fixed threaded rod process connection and are available in housings from miniature 1/2-inch diameter round up to rugged 32mm x 33mm rectangular bodies, suitable for applications with heavy vibration.
Rodless Slide
Rodless 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
Spring-loaded 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
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.
