ANSI/IEEE Magnetic proximity switch form

IEEE-library form of magnetic proximity switch: a magnetic proximity switch detects a documented magnetic target or field condition.

In plain English

What does ANSI/IEEE Magnetic proximity switch form mean?

This reference locates magnetic proximity switch in Autodesk's IEEE-oriented magnetic switches family. A magnetic proximity switch detects a documented magnetic target or field condition. The drawing identifies supply and output where applicable, and the equipment detail identifies the magnet or operating mechanism. The public library uses HPX1M 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

Locate the magnetic target as well as the switch body. A magnetic proximity input is different from a relay coil operating its own contacts. 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.
Coil
A wound conductor that can produce a magnetic field when energised.
Signal
Electrical information passed between devices, rather than necessarily the main power supply.

What it represents

This reference locates magnetic proximity switch in Autodesk's IEEE-oriented magnetic switches family. A magnetic proximity switch detects a documented magnetic target or field condition. The drawing identifies supply and output where applicable, and the equipment detail identifies the magnet or actuator. The public library uses HPX1M 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.

Locate the magnetic target as well as the switch body. A magnetic proximity input is different from a relay coil operating its own contacts. 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

  • Locate the magnetic target as well as the switch body.
  • 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 target reference
  • State output/contact type
  • Identify sensing arrangement

A distinction that matters

A magnetic proximity input is different from a relay coil operating its own contacts.
