Non-contacting rotary position sensors are extremely low wearing with two part sensors offering virtually infinite life. They have measurement ranges from 30° up to a full 360° rotation with absolute multi-turn also available on some models.
The majority of our non-contacting sensors use the Hall Effect principle which utilises magnetic fields to measure the rotary position of a moving object. They are well suited to a wide range of applications.
The main advantages of using this type of sensors are;
- The high reliability they offer
- They can be programmed to suit specific applications
- They offer high speed operation
- They operate in a relatively wide temperature range making them suitable for different environments.
- Low maintenance and long life
- Many have a higher IP rating of IP68 or IP69K
As Hall Effect sensors can be affected by external magnetic fields it is important to take the environment into consideration when selecting which sensor to use.
