IEC inductive proximity sensor: ferrous proximity switch, normally closed
Inductive proximity sensor form: Ferrous Proximity Switch, Normally Closed.
In plain English
What does IEC inductive proximity sensor: ferrous proximity switch, normally closed mean?
An inductive proximity sensor detects a metallic target through the effect it has on an electromagnetic sensing field. This entry identifies the ferrous proximity switch, normally closed form in the publisher's IEC-context family.
A simple example
A metal flag on a carriage can produce a controller input without touching a mechanical switch. The normally-closed designation starts with a conducting output or closed contact in the documented reference condition; operation changes that state.
What the drawings help you do
Target material, sensing distance and output circuit are product properties; an inductive mark does not identify PNP, NPN or a universal terminal assignment.
This particular reference
Inductive proximity sensor form: Ferrous Proximity Switch, Normally Closed. This entry adds the ferrous proximity switch, normally closed detail to the broader inductive proximity sensor family. Target material, sensing distance and output circuit are product properties; an inductive mark does not identify PNP, NPN or a universal terminal assignment.
- Normally open / normally closed
- The contact state in the normal condition defined for the drawing.
- Terminal
- An identified point where a conductor connects.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.

How to read it
- The normally-closed designation starts with a conducting output or closed contact in the documented reference condition; operation changes that state.
- Target material, sensing distance and output circuit are product properties; an inductive mark does not identify PNP, NPN or a universal terminal assignment.
Information to show or reference
- Identify the target, sensing mode and expected normal condition.
- Label supply, output and connector pins from the actual device diagram.
- Reference output circuit type, operating range and controller input.
A distinction that matters
This entry adds the ferrous proximity switch, normally closed detail to the broader inductive proximity sensor family. Target material, sensing distance and output circuit are product properties; an inductive mark does not identify PNP, NPN or a universal terminal assignment.
