A sensor terminal organises supply, return and signal connections for a documented sensor wiring arrangement.

## What it represents

A sensor terminal organises supply, return and signal connections for a documented sensor wiring arrangement. Multilevel construction may separate the signal path from bridged supply potentials.

## How to read it

- Follow each level to the sensor's supply and output terminals.
- 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 signal level
- Show supply bridges
- Reference sensor conductor count

## Important distinction

A sensor terminal's physical levels do not imply that all conductors are electrically common.

## Facts

- Drawing role: Wiring interface
- Representation scope: Functional concept; not an official standard graphic or a product footprint
- 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.
