Key Parameters: Parameter Category Specification Notes
Article Number WT2F-N140 T denotes Transmitter Unit
Sensor Type Through-beam Photoelectric Sensor, Transmitter Requires a compatible Receiver (e.g., WR2F-*)
Operating Range Long Range (e.g., 0.1 - 40 m or more) The "-N140" suffix is key; it often specifies a 40m range. Must be confirmed with datasheet.
Light Source Infrared LED (Modulated) Invisible light, optimized for long range and immunity to interference.
Supply Voltage 10 ... 30 V DC Standard DC operating voltage.
Current Consumption Typically < 50 mA
Connection Type Fixed Cable or Connector The suffix defines this. "N" often indicates a connector type (e.g., M12).
Housing Material Metal Provides high mechanical robustness.
Protection Rating IP67 Dust-tight and protected against temporary immersion.
Operating Temperature -25 °C ... +55 °C Standard industrial range.
Alignment Built-in alignment aid (e.g., sighting eye) For precise aiming at the receiver over long distances.
Key Takeaways:

Role: Long-range Through-beam Transmitter. Must be paired with a compatible receiver.

Primary Feature: Very long operating distance (likely up to 40 meters or more).

Robustness: Metal housing with IP67 rating for the most demanding industrial environments.

Performance: Uses modulated infrared light for high immunity to ambient light and electrical noise, ensuring reliable operation.
