Magnetic Target Disks
 Overview

In addition to detecting ferrous targets such as gear tooth wheels, bolt heads, etc., the Phares Electronics Zero Speed Switch Sensors also detect magnetic targets as do our Digital Output Hall Effect Sensors. To simplify installation, magnets are mounted in an aluminum disk that we refer to as a Magnetic Disk. Individual magnets are available and can be easily installed instead of a Magnetic Disk, if preferred.

Selecting a Magnetic Disk

Selecting a Magnetic Disk is very simple. We just need to know three things:
1) The sensor orientation in relation to the Magnetic Disk (Axial or Radial).

2) The preferred method to secure the Magnetic Disk to the shaft.
  • Bolt to shaft end.
  • Slide over shaft end, secure with two set screws.
  • Clamp around shaft via Split Coupling, secure with two set screws.
    (Set screws are knurled. Magnetic Disks keyed upon request.)
3) The bore size (I.D.) required.
That's it!

See the Ordering Information Table for part numbers and disk specifications.
