Employs a Hall Effect digital vane sensor and a permanent magnet in two small towers, separated by a 3.4 mm (0.135”) air gap. The output switches when a ferrous target passes between the towers. Typical targets are linear or rotary vanes using a square saw tooth or an open slot in a solid disk or band

  • Mechanically interchangeable with typical slotted optical switches
  • Robust, high speed sensing in dirty/dusty environments
  • No mechanical contacts to wear out
  • Open collector (sinking or NPN) output can be used with bipolar or CMOS logic circuits with suitable pull-up resistor
  • RoHS compliant
Typical Applications
  • Door/gate position control
  • Exercise equipment
  • Printers
