Rectangular metal sensor with red LED and 2 m PVC cable

Sick

Sick WT12-2N130 Photoelectric Proximity Sensor NPN

SKU CH-FFVW-FM484

Photoelectric proximity sensor with background suppression, 20–250 mm range, NPN output, IP69K metal housing, 2 m cable

  • Background suppression detects objects reliably up to 250 mm
  • Visible red LED simplifies alignment during setup
  • Potentiometer adjustment allows precise range tuning on site
  • IP69K metal housing withstands high-pressure washdown and harsh environments
  • NPN output with light/dark switching suits diverse PLC logic

Industrial Photoelectric Sensor with 250 mm Range

The Sick WT12-2N130 is a rectangular proximity sensor that uses visible red light with background suppression to detect objects between 20 mm and 250 mm. It operates on a 10 V DC to 30 V DC supply and provides an NPN switching output with light/dark switching modes. The unit suits automation engineers who need reliable presence detection in compact machine frames.

Sustained Operation in Harsh Environments

A zinc diecast metal housing rated IP69K protects the internal electronics during high-pressure washdowns and continuous exposure to moisture or dust. The sensor maintains a consistent response time of 330 µs while drawing 40 mA across an ambient operating range of –40 °C to +60 °C. PVC-jacketed cable ensures durable connectivity in moving or vibrating installations.

Installation Checks Before Ordering

Verify that your control system accepts an NPN switching signal and that the available supply voltage falls within the 10 V DC to 30 V DC window. Confirm the 2 m cable length and Ø 5 mm diameter suit your routing path and connector requirements. Ensure the 15 mm x 49 mm x 41.5 mm housing fits the intended mounting location without mechanical interference.

Questions about this item

Does the 40 mA draw at 10 V DC to 30 V DC create noticeable heat in a cabinet running continuously?

Power consumption is 40 mA, so heat contribution is minimal in a 10 V DC to 30 V DC system.

What supply voltage and cable preparation are required to connect the NPN output?

Provide 10 V DC to 30 V DC and terminate the 2 m PVC cable with 0.25 mm² conductors.

Will the 15 mm x 49 mm x 41.5 mm zinc housing fit the same cut-out as legacy 18 mm threaded sensors?

The rectangular metal housing differs from M18 threads, so a new mounting arrangement is needed.
