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