10 m through-beam with IP69K — what it means on a washdown line
The SICK WSE9M4-3P2230 is a through-beam photoelectric sensor from the W9 series, delivering a 10 m sensing range with a visible red PinPoint LED. The PNP output switches at 500 µs, and the M8 4-pin connector keeps wiring direct. The IP66/IP67/IP69K rating means the sensor body and optics withstand high-pressure, high-temperature washdown — suitable for food-and-beverage or pharmaceutical lines where sanitation cycles are routine.
Fit and integration — panel and machine interface
The housing measures 12.2 mm wide by 49.8 mm tall by 23.6 mm deep, matching the W9 family footprint for direct swap into existing brackets or DIN-rail mounts. The M8 4-pin connector mates with standard M8 pigtails; no special tooling required for panel integration. The 10–30 VDC supply range and 100 mA load current are compatible with most PLC digital inputs and industrial power supplies.
