1. OFF Omnipolar Sensor Omnipolar Sensor Omnipolar sensors are sensitive to either field polarity.

2. OFF N S ON Omnipolar Sensor Omnipolar Sensor A north or south field turns the sensor ON.

3. N S OFF Omnipolar Sensor Omnipolar Sensor A north or south field turns the sensor ON.

4. OFF Omnipolar Sensor Omnipolar Sensor The sensor turns OFF when the field is removed.

5. S N Omnipolar Sensor Omnipolar Sensor An opposite field also turns the sensor ON. OFF ON

6. OFF Omnipolar Sensor

7. OFF Bipolar Sensor Bipolar Sensor Bipolar sensors have opposite operate and release points.

8. N S Bipolar Sensor Bipolar Sensor A south field above a threshold latches the sensor ON. OFF ON

9. Bipolar Sensor Bipolar Sensor The sensor remains ON when the field is removed. ON

10. S N Bipolar Sensor Bipolar Sensor A north field turns the bipolar sensor OFF. ON

11. OFF S N Bipolar Sensor Bipolar Sensor A north field turns the bipolar sensor OFF.

12. OFF Bipolar Sensor Bipolar Sensor A north field turns the bipolar sensor OFF.

13. OFF Unipolar Sensor Unipolar Sensor Unipolar sensors are sensitive to only one polarity..

14. N S Unipolar Sensor Unipolar Sensor A south field above a threshold turns the sensor ON.. OFF ON

15. OFF Unipolar Sensor Unipolar Sensor A south field above a threshold turns the sensor ON.

16. S N OFF Unipolar Sensor Unipolar Sensor Unipolar sensors are insensitive to north fields.
