Sick VL18-2T2162 retro-reflective sensor
The Sick VL18-2T2162 is a cylindrical photoelectric retro-reflective sensor designed for industrial detection tasks. Its M18 x 1 threaded housing allows direct mounting into standard sensor ports on machinery or conveyor systems. The sensor emits an infrared LED beam axially along its 88 mm length. It suits automation engineers and maintenance technicians who need reliable presence detection without separate receiver wiring.
Sensing range up to 3.5 metres
The maximum sensing range spans 0.005 m to 3.5 m, while the defined sensing range covers 0.01 m to 3 m using a reflector. A 6° angle of dispersion creates a 30 mm light spot at the 3 m mark. Dark-switching TRIAC output delivers up to 300 mA at 25 Hz switching frequency with a 20 ms response time. The wide 20 V AC to 253 V AC supply voltage suits direct mains connection.
Simple three-wire cable installation
A fixed 2 m PVC cable with three 0.34 mm² conductors exits the IP67-rated PBT/PC housing for straightforward wiring. The Ø 4.7 mm cable diameter fits standard gland sizes and the sensor weighs 95 g. No potentiometer or teach-in adjustment is provided, so alignment must be set mechanically during mounting. The sensor operates from –25 °C to +60 °C. Buyers who need adjustable sensitivity or background suppression should select a different sensor type.

Questions about this item
How far can the sensor reliably detect a reflector in a real installation?
The rated sensing range is 0.01 m to 3 m with a standard reflector; the absolute maximum reaches 3.5 m under ideal conditions.
What mains voltage range and frequency does the AC TRIAC output support?
It operates on 20 V AC to 253 V AC at either 50 Hz or 60 Hz mains frequency.
What mounting thread and cable length does the cylindrical housing need?
The sensor uses an M18 x 1 thread and comes with a 2 m, 3-wire PVC cable of 4.7 mm diameter.
