It uses a red 660 nm LED and a retro-reflective sensing principle, designed to detect targets when used with a reflector, with a maximum range up to 4.8 m when paired with the PL80A reflector (0.1 m to 3 m typical without the reflector). \u003c\/p\u003e\n\u003cul\u003e \u003cli\u003eHousing: M18, dimensions 23.8 mm × 46.7 mm × 33.6 mm\u003c\/li\u003e \u003cli\u003eSensing method: Retro-reflective photoelectric, compatible with reflector PL80A\u003c\/li\u003e \u003cli\u003eSensing range: 0.1 m to 3 m typical; up to 4.8 m with PL80A reflector\u003c\/li\u003e \u003cli\u003eLight source: Red LED, 660 nm\u003c\/li\u003e \u003cli\u003eSupply voltage: 10–30 V DC; ripple \u0026lt; 5 Vpp\u003c\/li\u003e \u003cli\u003eCurrent consumption: ~20 mA\u003c\/li\u003e \u003cli\u003eOutput: PNP switching output, max 50 mA; light\/dark operation selectable\u003c\/li\u003e \u003cli\u003eSwitching frequency: 400 Hz\u003c\/li\u003e \u003cli\u003eConnection: M8, 4-pin\u003c\/li\u003e \u003cli\u003ePart number: 1047826; Manufacturer: SICK\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIt includes protective features noted in the datasheet, such as reverse-polarity protection on supply connections and protection against overcurrent\/short-circuit on outputs.
