A magnetic proximity switch detects a documented magnetic target or field condition.

## What it represents

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.

## 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

## Important distinction

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

## Facts

- Drawing role: Actuated indication
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HPX1M, VPX1M (Autodesk identifiers; not IEC symbol numbers)
- Identifier status: The short label is a functional lookup label, not an assigned IEC or IEEE symbol number. Any separately listed Autodesk code is a verified vendor block name.
