This linear transducer series is characterized by its robust housing and easy mounting via rod end bearings. The wiper block is mechanically decoupled backlash-free from the actuating rod, hereby ensuring high accuracy and long life. The sensor can be used in a wide range of closed-loop control applications, including linear position sensing in industrial automation, mobile electronics and also in very fast robotics, e.g. simulator actuation.

Special Features

• Rod and cylinder design with twin slide bearings and lip seal

• Backlash free mounting via spherical rod end bearings with large pivot angle of ±12.5 degrees

• Outstanding linearity

• Resolution better than 0.01 mm

• Long life up to 50 Mio. movements, depending on application

• Protection class IP65

• Cable or connector version available
