Sick WL14-2N430 Photoelectric Retro-Reflective Sensor NPN

SKU CH-Q67Y-NVV8N

Photoelectric retro-reflective sensor with NPN complementary output, 0.15–6 m range, visible red LED, M12 connector, IP67 ABS housing

  • Photoelectric retro-reflective sensing up to 6 m range
  • Visible red LED light at 645 nm wavelength
  • NPN complementary output with 100 mA switching current
  • IP67 enclosure rating for harsh environments
  • Compact 17.6 × 75.5 × 33.5 mm ABS housing

Industrial Photoelectric Sensor

The Sick WL14-2N430 is a retro-reflective photoelectric sensor with dual-lens optics and visible red LED emission. It operates on 10 V DC to 30 V DC supply voltage and provides an NPN complementary switching output. The rectangular ABS housing measures 17.6 mm by 75.5 mm by 33.5 mm and weighs 40 grams. It achieves an IP67 enclosure rating for dust and water protection.

M12 Connector Integration

A male M12 4-pin connector handles power and signal without hard wiring. The sensor draws 35 mA and switches at up to 200 Hz with a 2.5 ms response time. Output current reaches 100 mA maximum. Circuit protection covers reverse polarity, short circuit and overload. The polarisation filter helps reject false triggers from shiny surfaces.

Automation Engineers Seeking Fixed Range

This unit suits engineers who need a pre-set sensing window of 0.15 m to 4 m and a 645 nm light source. It is not for buyers who require adjustable sensitivity or teach-in alignment. It does not fit applications needing AC supply or PNP output logic. The fixed 2° dispersion angle limits use where narrow-beam precision is essential.

Highlights

  • Photoelectric retro-reflective sensing up to 6 m range
  • Visible red LED light at 645 nm wavelength
  • NPN complementary output with 100 mA switching current
  • IP67 enclosure rating for harsh environments
  • Compact 17.6 × 75.5 × 33.5 mm ABS housing
