A capacitive proximity switch detects a target through a change in its sensing capacitance.

## What it represents

A capacitive proximity switch detects a target through a change in its sensing capacitance. Its supply and switching output are shown separately from the target or process material.

## How to read it

- Read sensitivity and target conditions from the product selection.
- 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

- Identify supply terminals
- State output function
- Reference target material and sensitivity

## Important distinction

Capacitive sensing is different from inductive metal-target sensing.

## Facts

- Drawing role: Actuated indication
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- Public vendor block reference: HPX1C, VPX1C (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.
