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