Rectangular metal photoelectric sensor with red laser emitter and M12 connector

Sick

Sick WS/WE12L-2P430 photoelectric sensor PNP

SKU CH-4581-72VXW

A through-beam photoelectric sensor with laser light source detecting objects up to 80 m using visible red light at 650 nm

  • Visible red laser spots objects up to 80 m away
  • 5 kHz switching catches fast-moving targets reliably
  • IP67 and IP69K metal housing survives harsh wash-downs
  • 10–30 V DC supply fits standard industrial power rails
  • Compact 15 × 49 × 41.5 mm body fits tight machine spaces

Through-beam sensor with 80 m range

The Sick WS/WE12L-2P430 is a rectangular through-beam photoelectric sensor designed for industrial detection tasks. It uses a visible red laser operating at 650 nm with a spot diameter of 150 mm at 60 m. The sensor suits applications requiring detection of small objects or items moving at high speeds. Its metal housing and IP67/IP69K ratings allow use in harsh environments.

Sustained switching at 2 500 Hz

Under continuous operation the sensor maintains a switching frequency of 2 500 Hz with a response time of 200 µs. The sender draws 45 mA and the receiver 15 mA from a 10 V DC to 30 V DC supply with 5 Vpp ripple tolerance. PNP output delivers up to 100 mA with signal voltages of Uv minus less than 2.9 V for HIGH and 1.5 V or less for LOW. Circuit protection covers reverse polarity, short-circuit and overload conditions.

M12 connector limits cable integration

Connection is made through a male M12 4-pin connector, fixing the pin count and cable type for installation. The enclosure meets IP67 and IP69K, so the interface survives high-pressure washdown but does not exceed those ingress ratings. Operating temperature spans minus 10 °C to plus 50 °C, setting the environmental boundary for reliable signal transmission. The housing measures 15 mm by 49 mm by 41.5 mm and weighs 260 g.

Questions about this item

How much power does the WS/WE12L-2P430 draw when it runs continuously?

The sender uses 45 mA and the receiver 15 mA at 10–30 V DC, so total consumption stays below 60 mA.

What voltage supply and connector does the sensor need to operate?

It requires 10–30 V DC and connects via a 4-pin M12 male plug.

Will the 650 nm laser spot stay small enough to detect fast-moving parts on an older conveyor line?

At 60 m the spot is Ø 150 mm and the sensor switches at 2,500 Hz, suitable for high-speed detection.
