SICK Glass Fibre Optic Sensor with PNP Output, IP50 Protection, 24V DC, 16μs Response Time

SICK WLL180T-P474 Glass Fibre Optic Sensor is a high-speed sensor designed for industrial automation and control applications. It operates with a PNP output and features an IP50 protection rating, working reliably at a supply voltage of 24V DC with an ultra-fast response time of 16 microseconds. Utilizing glass fibre optic technology combined with a LED light source, it provides accurate detection even under challenging ambient conditions such as dust, spray, and mist.

The sensor is equipped with an M8 male connector terminal and offers a high switching frequency of 31.2 kHz, suited for rapid process detection tasks. Its durable plastic housing is able to operate within a temperature range from -25°C to 55°C, and measures 34.6mm in length, 10.5mm in width, and 71.9mm in depth, making it compact and versatile for integration. The WLL180T-P474 comes with CE and UL certifications, ensuring compliance with safety and performance standards.

Setup and programming are simplified by features including dual 4-digit displays showing programming steps and status, adjustable hysteresis, rotatable display screen, and programmable time delays. The sensor family supports both stand-alone and bus configurations, allowing networked operation with cross-talk prevention through integrated anti-interference logic.

Typical industrial use cases for this sensor include detecting printed circuit boards, measuring liquid levels in bottles, classifying logs, monitoring parts in injection molding tools, and ensuring presence and position accuracy in robotic grippers or loading mechanisms. Its reliable optical detection extends to vacuum environments and protrusion monitoring in solar cell assembly.

The sensor incorporates a selectable response time up to 16 µs. Sensing range can extend up to 20 meters in through-beam systems and 1,400 mm in proximity setups. Highly resistant to interference, ideal for harsh factory floor conditions.

Flexible parameter adjustments suited for detecting small or transparent objects. High resolution signal processing ensures precise detection results. Explore our wide range of sensors at EnvMart for all your automation needs.
