ANSI/IEEE Ultrasonic proximity switch form
IEEE-library form of ultrasonic proximity switch: an ultrasonic-switch representation identifies presence or distance switching using an ultrasonic sensing principle.
In plain English
What does ANSI/IEEE Ultrasonic proximity switch form mean?
This reference locates ultrasonic proximity switch in Autodesk's IEEE-oriented ultrasonic switches family. An ultrasonic-switch representation identifies presence or distance switching using an ultrasonic sensing principle. The public library uses HPX1U 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
State the sensing role, output type and selected device connection separately. Ultrasonic sensing is distinct from inductive, capacitive and optical sensing. State the sensing role, output type and selected device connection separately. Ultrasonic sensing is distinct from inductive, capacitive and optical sensing. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.
