Engineering selection guide

Reed sensor and float switch selection details

Define sensing products by housing style, actuation distance, magnet/float geometry, contact behavior, cable/connector, material compatibility and installation direction.

Selection checklist

  • Sensing mode: proximity, door, level or flow
  • Housing material and mounting style
  • Normally-open / normally-closed behavior
  • Magnet, gap, float and target geometry
  • Cable length, connector and sealing requirement
  • Media compatibility and operating temperature
