The difference between shielded and non-shielded proximity switches

The main differences between shielded and non-shielded proximity switches are as follows:

1. Shielded Proximity Sensors

· Installation: Can be mounted flush on metal surfaces

· Detection distance: Shorter (usually about 70% of the non-shielded type)

· Electromagnetic field direction: Mainly focused on the front

· Interference immunity: Stronger, suitable for metal environments

· Housing design: The front of the probe usually has a metal shield

2. Non-Shielded Proximity Switches

· Installation: Need to be installed on a protruding metal surface

· Detection distance: Longer

· Electromagnetic field direction: Expanding forward and sideways

· Interference immunity: Slightly weak, need to keep a certain space to prevent interference

· Housing design: Probe exposed part is longer
