Proximity / Limit / Position Sensor
Confirms presence, position, and motion — the foundation of safe industrial automation.
What Does a Proximity / Limit / Position Sensor Measure?
Proximity, limit, and position sensors detect the presence, absence, or position of objects and machine components without requiring continuous human intervention. They provide definitive confirmation of motion completion, end positions, and safe states in automated and semi-automated systems.
Signal Output
- Digital ON/OFF output (NPN / PNP)
- Relay contact (limit switches)
- Digital communication (IO-Link, RS485)
- Status signals: Position reached / Not reached
What Does the Signal Mean?
| Sensor State | Industrial Meaning |
|---|---|
| Sensor ON (target detected) | Correct position or presence confirmed |
| Sensor OFF | Object absent or position not reached |
| Intermittent switching | Misalignment, vibration, or loose mounting |
| No response | Sensor failure or wiring issue |
