Industrial Through-beam Sensor for 25 m Range
The Sick WSE27-3P2450 is a through-beam photoelectric sensor designed for industrial detection tasks requiring a 25 m sensing range. It emits visible red LED light at 645 nm with a 1.5° dispersion angle, creating a 600 mm spot at maximum distance. The sensor operates on 10 V DC to 30 V DC supply voltage and provides a PNP complementary output with light or dark switching modes.
Stable Switching at 1000 Hz Under Continuous Use
The receiver draws 35 mA while the sender consumes 50 mA, and the unit delivers a 500 µs response time with a 1000 Hz switching frequency for reliable high-speed detection. Output current is limited to 100 mA with signal voltage at approximately supply minus 2.5 V for HIGH and 0 V for LOW. An angle of reception of 3° and built-in circuit protection (A, B, C) maintain consistent performance across the operating temperature span of –40 °C to +60 °C.
ABS Housing with IP69K Rating and M12 Connector
The rectangular housing measures 24.6 mm x 80.6 mm x 54 mm and uses ABS plastic with PMMA optics, weighing 200 g. An IP69K enclosure rating withstands high-pressure washdown, while the 4-pin M12 male connector simplifies installation in control cabinets or on machinery frames. A test input allows the sender to be switched off by pulling TE to 0 V, and UL file numbers NRKH.E181493 and NRKH7.E181493 confirm compliance.

Questions about this item
How much power does the WSE27-3P2450 draw when running continuously on a 24 V supply?
The sender consumes 50 mA and the receiver 35 mA, both within the 10 V DC to 30 V DC supply range, so total current stays below 100 mA during all-day operation.
What cable or connector must I already have to wire the M12 4-pin plug on this sensor?
You need a matching 4-pin M12 female connector or pre-wired cordset; the sensor housing only provides the male M12, 4-pin connection.
Will the visible red 645 nm beam and 1.5° dispersion work reliably alongside older infrared sensors on the same line?
The 645 nm visible red LED with approx. 1.5° dispersion and 3° reception angle minimises cross-talk, so it can run beside legacy infrared units without interference.
