Small rectangular plastic sensor with potentiometer and cable

Sick

Sick WT100-N1412 Photoelectric Proximity Sensor NPN 10-30 V DC 100 mA 1000 Hz IP65

SKU CH-TF79-THP61

Photoelectric proximity sensor with background blanking detects objects from 10 mm to 100 mm using visible red LED light at 680 nm

  • Background blanking ignores objects beyond 140 mm
  • Visible red LED spot 8 mm at 90 mm distance
  • NPN output switches up to 100 mA load
  • 1000 Hz switching frequency for fast detection
  • IP65 rated ABS housing withstands dust and water jets

Industrial Proximity Sensor

The Sick WT100-N1412 is a rectangular photoelectric proximity sensor that uses background blanking to detect objects between 10 mm and 100 mm. It operates on a 10 V DC to 30 V DC supply and provides an NPN switching output rated at 100 mA. The 2 m PVC cable and IP65 enclosure suit industrial automation and material-handling tasks.

Thermal Noise Power

The sensor draws 30 mA from the supply with a ±10 % ripple tolerance and operates silently with no moving parts. Its plastic ABS/PC/POM housing and PMMA optics withstand ambient temperatures from –25 °C to +55 °C. The IP65 rating protects internal electronics from dust and low-pressure water jets in normal use.

Sustained Load Behaviour

A 0.5 ms response time and 1,000 Hz switching frequency allow continuous high-speed detection without performance drop-off. The potentiometer offers 270° of adjustment for stable light/dark switching over long shifts. The visible red LED at 680 nm maintains a consistent 8 mm spot at 90 mm distance during extended operation.

Questions about this item

How do I set the sensing range on the potentiometer and what is the adjustment range?

Turn the 270° potentiometer while watching the output LED; the sensor detects from 10 mm to 100 mm with background blanking.

Which parts need replacement after long-term use in an IP65 environment?

The 2 m PVC cable and PMMA optics face abrasion and UV exposure; inspect them regularly and replace if the jacket cracks or the lens clouds.

At what ambient temperature does the sensor reach its operating limit first during continuous duty?

The upper limit is +55 °C; above this the 30 mA supply current and 100 mA output rating are no longer guaranteed.
