An inductive proximity switch detects a documented target without a mechanical contact actuator.

## What it represents

An inductive proximity switch detects a documented target without a mechanical contact actuator. The schematic shows its supply and output arrangement, while target distance and material are specified elsewhere.

## How to read it

- Distinguish a two-wire output path from a three-wire supply and signal arrangement.
- 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

- State output type
- Identify supply and common
- Reference target and sensing distance

## Important distinction

An inductive proximity switch detects an electromagnetic target interaction, not capacitance or an optical beam.

## Facts

- Drawing role: Actuated indication
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HPX1I, VPX1I (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.
