Notes 12

  1. Specifications are not constant across entire magnetic range.
  2. Customer must exercise care in handling and mounting to prevent damage to internal components and subsequent changes to sensor performance.
  3. For information about performance, custom configuration (i.e. wire length or color; connectors; operational variation), or packaging contact our Sales department.
  4. Information contained hereon is for informational purposes only and should not be deemed as accurate for a specific application. Consult factory for specific application information and/or latest revision.
  5. External magnetic field of proper polarity latches common reed to one of the outputs. Common reed transfers and latches to the other output under external magnetic field of opposite polarity.
