Sick VL18-2T2460 Photoelectric retro-reflective sensor

SKU CH-4B5K-23DSP

A photoelectric retro-reflective sensor detecting objects from 0.01 m to 3.5 m with an M18 cylindrical housing and M12 connector

  • Retro-reflective sensing up to 3.5 m range
  • Wide 20 – 253 V AC supply voltage
  • IP67 enclosure resists dust and water ingress
  • M12 4-pin connector for quick installation
  • TRIAC dark-switching output handles 300 mA load

Cylindrical M18 retro-reflective sensor

The Sick VL18-2T2460 is a photoelectric retro-reflective sensor built for industrial detection tasks. Its cylindrical M18 × 1 housing measures 92 mm in length and carries an axial optical axis. The unit operates on 20 V AC to 253 V AC at 50 Hz or 60 Hz and connects via a 4-pin M12 male connector.

Sensing range and switching limits

The sensor detects objects from 0.005 m to 3.5 m, with a specified sensing range of 0.01 m to 3 m using infrared LED emission. A 6° dispersion angle produces a 30 mm light spot at 3 m distance. Dark-switching TRIAC output delivers up to 300 mA at a 25 Hz switching frequency and a 20 ms response time, so it suits moderate-speed presence checks rather than high-speed counting.

IP67 enclosure for harsh environments

The plastic PBT/PC housing and PMMA optics meet IP67, allowing use in wet or dusty conditions from –25 °C to +60 °C. Protection class III and built-in circuit protection C safeguard the electronics. Buyers who need background suppression, teach-in adjustment or a DC-only supply voltage should select a different sensor type.

Questions about this item

Which sensing range version should I choose between the maximum 0.005 m ... 3.5 m and the standard 0.01 m ... 3 m?

The sensor offers a maximum sensing range of 0.005 m to 3.5 m and a standard sensing range of 0.01 m to 3 m. Select the maximum range for detecting objects at greater distances up to 3.5 m.

What does the 300 mA output current mean for my load?

The TRIAC switching output supports a maximum load current of 300 mA at 20 V AC to 253 V AC. Ensure your connected load does not exceed this current rating.

How does the M12 4-pin connector and TRIAC output cap the switching frequency?

The sensor switches at 25 Hz with a 20 ms response time via the M12 4-pin connector. The TRIAC output is rated for 300 mA maximum at 253 V AC.
