Sick

Sick VL18-3F3240 photoelectric retro-reflective sensor PNP

SKU CH-1TKB-BG6JS

A photoelectric retro-reflective sensor with 0.05 m to 3.7 m range, PNP output and IP67 metal housing for industrial detection

  • Detects objects up to 3.7 m away with visible red LED light
  • Adjust sensitivity precisely using 270° potentiometer for reliable operation
  • Fast 2 ms response time suits high-speed detection tasks at 250 Hz
  • Rugged IP67 nickel-plated brass housing withstands –25 °C to +70 °C environments
  • PNP light-switching output delivers 100 mA from 10–30 V DC supply

Sick VL18-3F3240 retro-reflective sensor

This cylindrical M18 photoelectric sensor uses a polarising filter and visible red LED to detect objects up to 3.7 m away. It operates on 10–30 V DC with a PNP light-switching output rated at 100 mA. The IP67-rated nickel-plated brass housing suits industrial automation and conveyor applications.

Sustained load behaviour

A 250 Hz switching frequency and 2 ms response time maintain consistent detection on fast-moving lines. The 30 mA current draw stays stable across the –25 °C to +70 °C temperature range. Circuit protection A, B, C and D guards against wiring faults during continuous operation.

Pre-installation checks

Verify your control system accepts a PNP output with a 4-pin M12 connector. Confirm the 10–30 V DC supply matches your available voltage rail. Ensure the 78 mm housing length and M18 thread fit the mounting bracket and clearance.

Questions about this item

How much heat does the 30 mA sensor generate when powered continuously at 24 V DC?

The sensor draws 30 mA from a 10–30 V DC supply, so at 24 V it consumes under 1 W and has no moving parts, keeping heat negligible in its IP67 metal housing.

What cable or connector do I need to wire the M12 4-pin plug on this sensor?

A standard 4-pin M12 female cordset matches the male connector; the sensor requires a 10–30 V DC supply and a PNP-compatible input capable of 100 mA.

Will the visible red LED and 250 Hz switching work with my older PLC input card?

The sensor outputs a PNP light-switching signal at up to 250 Hz with a 2 ms response time, compatible with PLC inputs rated for that speed and voltage range.
