ANSI/IEEE Three-wire inductive proximity switch form
IEEE-library form of three-wire inductive proximity switch: a three-wire inductive proximity switch uses separate supply, common and output conductors.
In plain English
What does ANSI/IEEE Three-wire inductive proximity switch form mean?
This reference locates three-wire inductive proximity switch in Autodesk's IEEE-oriented inductive switches family. A three-wire inductive proximity switch uses separate supply, common and output conductors. Its output polarity and load connection must match the receiving input module. The public library uses HPX11IN3 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
A simple example
Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence.
What the drawings help you do
Follow the output common and receiving input polarity together. Three-wire construction describes wiring; normally open or normally closed describes the output's documented switching behaviour. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

- 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.

What it represents
This reference locates three-wire inductive proximity switch in Autodesk's IEEE-oriented inductive switches family. A three-wire inductive proximity switch uses separate supply, common and output conductors. Its output polarity and load connection must match the receiving input module. The public library uses HPX11IN3 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.
Read the operating mechanism and the contact reference state together. Cross-reference every associated contact to the same device and show which movement, signal or reset changes its condition; the symbol alone does not establish the complete switching sequence.
Follow the output common and receiving input polarity together. Three-wire construction describes wiring; NO or NC describes the output's documented switching behaviour. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.
How to read it
- Follow the output common and receiving input polarity together.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Name three terminals
- State PNP or NPN as specified
- Reference PLC input compatibility
A distinction that matters
Three-wire construction describes wiring; NO or NC describes the output's documented switching behaviour.
