Some points to keep in mind while mounting Ferrous Proximity sensors are:
- It is recommended that non-ferrous brackets and hardware are used to mount the sensors.
- The FP family of proximity sensors have an internal magnet; the sensor should not be mounted directly on ferrous material. The FP2000, FP3000 and FP4000 have plastic spacers provided the sensor is not affected if mounted on ferrous material.
- Additionally, the sensor should be mounted so that any ferrous material, apart from the target in the area does not affect the magnetic field of the sensor. As a rule, keep all ferrous material at a minimum of the air gap “break” distance from the package.
- Due to the large hysteresis associated with proximity sensors, vibration is not as large a problem as it is with position and speed sensors and should still be taken into consideration.
- When the target (ferrous object or magnet) approaches the sensor surface, it should approach at a 90-degree angle and be as large as feasible in the design. The target should not slide by parallel to the sensing zone of the sensor since it can create a “Double Switch”.
