ANSI/IEEE Ultrasonic NC switching output form
IEEE-library form of ultrasonic nc switching output: this form identifies a normally-closed switching output in the ultrasonic sensor family.
In plain English
What does ANSI/IEEE Ultrasonic NC switching output form mean?
This reference locates ultrasonic nc switching output in Autodesk's IEEE-oriented ultrasonic switches family. This form identifies a normally-closed switching output in the ultrasonic sensor family. The public library uses HPX12U 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
Identify the reference sensing condition and connected control input. Normally closed does not imply a safety-rated diagnostic output. Identify the reference sensing condition and connected control input. Normally closed does not imply a safety-rated diagnostic output. 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.
- Signal
- Electrical information passed between devices, rather than necessarily the main power supply.
- Rating
- A value stating the conditions for which equipment is specified.
