The Sick 1058188 (Model WTB9M4L-3P1161) is a high-performance diffuse reflection photoelectric sensor engineered for dependable object detection in industrial automation applications. Part of the WTB series, this sensor combines advanced sensing technology, durable construction, and versatile mounting options, making it ideal for conveyor monitoring, packaging lines, material handling, and automated production processes.

One of the key features of the WTB9M4L-3P1161 is its detection range of up to 9‚ÄØm, allowing accurate detection of objects over medium distances. Its diffuse reflection design eliminates the need for a separate reflector, simplifying installation and minimizing setup time. The sensor provides consistent performance in environments with dust, vibrations, or varying lighting conditions, ensuring reliable operation across diverse industrial applications.

The sensor incorporates PinPoint visible red LED technology, which emits a bright, focused light spot for precise alignment during installation. This concentrated beam allows for accurate detection of small, dark, or reflective objects, crucial for high-speed and high-precision automation processes. The precise LED alignment reduces setup errors and guarantees stable operation even in fast-moving production lines.

Durability is a standout feature of the WTB9M4L-3P1161. Its IP67-rated housing offers excellent protection against dust, water, and other environmental challenges, enabling reliable operation even in harsh industrial conditions. The M12 connector ensures a secure and standardized electrical connection, facilitating seamless integration into automation systems while maintaining long-term operational stability. The combination of rugged housing and reliable connectivity reduces maintenance needs and ensures consistent sensor performance over time.

Electrically, the sensor features a PNP output and supports both Light On and Dark On switching modes, providing flexible integration into various automation control systems. Its fast response time enables precise detection of high-speed moving objects, making it suitable for conveyor monitoring, sorting, and packaging applications. Operating within a 10 V to 30 V DC supply range, the WTB9M4L-3P1161 performs reliably across temperatures from –25 °C to +55 °C.

Compact, efficient, and versatile, the WTB9M4L-3P1161 can be installed in space-constrained areas without compromising detection performance. Its combination of medium-range diffuse reflection sensing, precise PinPoint LED alignment, rugged IP67 housing, and flexible PNP output makes it a dependable solution for engineers and automation professionals seeking accurate and reliable object detection.
