Position sensors are available in both contacting

Linear position sensors are available in both contacting & non contacting technologies including; potentiometric displacement sensor, Magneto-Restrictive, Hall Effect, Encoder and LVDT/RVDT in various sensor packages. Different types of technology ensure the most accurate measurements in different applications.
You may be surprised to know that position sensors are very common in everyday life; you have probably come into contact with position sensors as they are used in;
· Elevators have position feedback which typically use encoders
· For use in Cars for things such as throttle control & seat memory
· Rudder reference & Steering on boats & ships
· The control of imaging & treatment machines in hospitals
· Wind turbines for monitoring the wind direction
