Sick WSE27-3P2450 Through-beam Photoelectric Sensor PNP

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.
