These Proximity Sensors use high-frequency oscillation. They resist heat, chemicals, and water better than Rectangular Sensors. They are available in both shielded and unshielded models.
Proximity Sensors are available in models using high-frequency oscillation to detect ferrous and non-ferrous metal objects and in capacitive models to detect non-metal objects. Models are available with environment resistance, heat resistance, resistance to chemicals, and resistance to water.
Features
- Only 5.5 ´ 5 mm with a built-in Amplifier.
- Maximum sensing distance: 5 mm. Stable detection even with workpiece fluctuations.
- Response frequency: 1
- Low current
