The Differences Between A Shielded and Unshielded Inductive Proximity Sensor

There are 3 differences between a   shielded proximity sensor (also know as flush sensor) and   unshielded proximity sensor (also called non flush proximity sensor), so what are they? Let’s have a look them in following parts in this article.

PBT material have many advantages, such as strong stength, and non-flammable, and so on. The PBT head in our  proximity sensors  is in blue colour, some proximity sensor manufacturers might use  orange (Autonics) colour or green colour(Pepperl+Fuchs). When putting a same model shielded and unshielded proximity sensors together, we can clear see, the unshielded proxi
