SICK Glass and Plastic Fibre Optic Sensor with NPN Output IP50 24V dc WLL180T-N432

The SICK WLL180T-N432 is a glass and plastic fibre optic sensor featuring an NPN output and an IP50 rated plastic housing. Operating at 24V dc, this sensor delivers one of the fastest response times available in the industry, down to 16 microseconds. It provides superior sensing distances up to 20 meters through a beam system or 1,400 mm in proximity sensing applications.

Its bright LED light source and high switching frequency of 31.2 kHz ensure rapid and reliable detection even in challenging ambient conditions such as dust, mist, spray, or water jets. The sensor includes a two 4-digit digital display that facilitates visualization of programming steps, status indication, and target versus actual values.

Designed for flexible installation and operation, the WLL180T sensor supports bus configurations to network multiple sensors, allowing copying of settings across devices and eliminating cross-talk via integrated anti-interference logic. Adjustable hysteresis and programmable time delays enable precise tuning to application requirements, making it ideal for detecting tiny or transparent objects.

Common industrial applications include printed circuit board detection, fill level monitoring in bottles, log detection and classification, gripper presence verification, injection molding tool monitoring, and solar cell protrusion monitoring. The sturdy plastic housing operates effectively between -25°C and 55°C, suitable for demanding industrial environments.

Compliance with CE and UL standards assures users of product safety and regulatory adherence. This product is manufactured in China and comes as part of the WLL180T series known for its high performance and reliability.
