Operating a Reed Sensor
A Reed Sensor is an omnipolar, magnetically activated switch, which means a magnet can approach it from any angle, with either pole. Several possible operating methods are shown below.

  •  Perpendicular Magnet Travel
  •  Parallel Magnet Travel
  •  Nose-To-Nose Activation
  •  Rotational Magnet Travel

Reed Sensors

 
  Perpendicular Magnet Travel

This method maximizes air gap.
Perpendicular Operation

 
  Parallel Magnet Travel

Up to three operations possible with one magnet.
Parallel Operation

 
  Nose-To-Nose Activation

Both ends of the magnet work equally well.
Nose-to-nose Operation

 
  Rotational Magnet Travel

Multi-pole ring magnets can be used to achieve a larger number of operations per rotation.

Rotational Operation
