Switch

The following variations of switch type Hall effect ICs are available:

- Single pole detection switch - Two pole detection switch
  • Continuous excitation type
  • Pulse excitation type
  • Single output type
  • Dual output type

Unipolar Hall effect IC

Explanation of operation
On/off is switched depending on the intensity of the magnetic field of the S-pole of the magnet. This type is used for position detection.

Operation diagram
å<.ä½o?
  • When the S-pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds Bop, Vout changes from H to L.
  • When the S-pole of the magnet leaves the marked side of the Hall effect IC and the magnetic flux density decreases below Brp, Vout changes from L to H.

    Omnipolar Hall effect IC
    One output for S or N pole

    Explanation of operation
    On/off is switched depending on the intensity of the magnetic field of the S-pole or N-pole of the magnet.
    Operation diagram
    å<.ä½o?
  • When the S-pole or N pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds BopS or BopN, Vout changes from H to L.
  • When the S-pole or N-pole of the magnet leaves the marked side of the Hall effect IC and the magnetic flux density decreases below BrpS or BrpN, Vout changes from L to H.

    Two output for S and N pole

    Explanation of operation
    On/off is switched depending on the intensity of the magnetic field of the magnet (S-pole or N-pole).
    There are two output terminal systems, and each detects only the S-pole or N-pole.

    Operation diagram
  • When the S-pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds BopS, Vout1 changes from H to L.
  • When the S-pole of the magnet leaves the marked side of the Hall effect IC and the magnetic flux density decreases below BrpS, Vout1 changes from L to H.
  • When the N-pole of the magnet approaches the marked side of the Hall effect IC and the magnetic flux density exceeds BopN, Vout2 changes from H to L.
  • When the N-pole of the magnet leaves the marked side of the Hall effect IC and the magnetic flux density decreases below BrpN, Vout2 changes from L to H.
