Industrial sensing device
The Sick WL23-2P2430 is a photoelectric retro-reflective sensor designed for automation and detection tasks. It operates on a 10 V DC to 30 V DC supply and provides a PNP complementary output with light/dark switching. The rectangular plastic housing measures 24.6 mm x 80.6 mm x 54 mm and weighs 100 g. It connects via a male M12 4-pin connector.
Range and response limits
The sensor uses visible red LED light at 660 nm with a 1.5° dispersion angle. Maximum sensing range reaches 10 m while the specified operating range is 0.3 m to 7 m. Light spot diameter is 45 mm at 2.7 m distance. Switching frequency is 200 Hz with a 2.5 ms response time. The IP67 enclosure rating protects against dust and temporary immersion. Operating temperature spans –25 °C to +60 °C.
PNP output specification
The single specification that decides fit is the PNP switching output with a maximum load current of 100 mA. Signal voltage high level approximates supply voltage minus 2.5 V while low level is near 0 V. This output type suits controllers expecting a positive-switched signal. Buyers whose systems require NPN sinking logic or higher current capacity must select a different sensor.

Questions about this item
Which sensing range version suits a 5 m application, the 0.1 m to 10 m maximum or the 0.3 m to 7 m rated range?
Use the 0.3 m to 7 m rated range; it guarantees reliable detection at 5 m, while the 0.1 m to 10 m figure is the absolute maximum under ideal conditions.
What does the 200 Hz switching frequency mean for a conveyor running at 1 m/s?
At 200 Hz the sensor can resolve objects spaced 5 mm apart at 1 m/s, so it will reliably detect each item on a fast line.
What does the M12 4-pin connector cap in terms of output current and voltage?
The connector carries a PNP output rated for 100 mA at 10 V DC to 30 V DC, limiting the load you can drive directly.
