The WLL180T-P432 with SENSOR, FIBRE OPTIC, PNP, CABLE is an industrial sensor manufactured by Sick, a leading manufacturer of electronic sensors. It is an optical, background-suppressed thru-beam sensor that uses a PNP polarity. The sensor is designed to detect objects and measure distances up to 12 m, and output an electrical signal when illuminated. Additionally, it is equipped with two fibres which can be guided through conduits or small openings to provide a flexible installation in difficult to access areas. It is rated to operate in temperatures ranging from -25 to +65 °C, and is also resistant to reverse polarity and electrostatic discharge, making it suitable for harsh industrial environments.
