Technical & Operating Data
| Feature | Specification |
| Sensing Range ($s_n$) | 20 mm |

Load Ratings (Power Consumption)
The sensor supports different power loads depending on the operating voltage:
-
At 220 V: 500 / 100 VA
-
At 110 V: 250 / 50 VA
-
At 42 V: 100 / 20 VA
Wiring & Connection
The sensor uses a 2-wire AC connection. According to the diagram on the label:
-
Wire 1 (braun/brown): Connects to Line ($L1$).
-
Wire 2 (blau/blue): Connects to the Load (Consumer).
-
Output Function: Normally Open (NO). The circuit closes when a metal object is within 20 mm of the orange sensing face.
Key Features
-
Large Sensing Range: The 20 mm range is significantly higher than standard M12 or M18 sensors, making it ideal for large machinery parts.
-
Direct AC Switching: Can switch AC loads (like contactors or relays) directly without needing a separate DC power supply.
-
Robust Design: The orange plastic housing is designed for heavy industrial environments.
Safety Note: Since this device operates on high-voltage AC ($20\text{–}250\text{ V}$), ensure the power is disconnected before wiring. The “non-flush” ($nb$) designation means the orange head should not be recessed into a metal mounting bracket, or it will stay permanently triggered.
