SICK WL24-2V240 Retro-Reflective Photoelectric Sensor with Long Sensing Range
The SICK WL24-2V240 retro-reflective photoelectric sensor is engineered for stable object detection across long distances in industrial environments where reliability is critical. Its dual-lens optical design supports consistent sensing up to 15 meters, helping prevent false triggers caused by misalignment or signal loss. A visible red LED simplifies installation and alignment, while selectable PNP/NPN and light or dark switching ensure compatibility with most control architectures. Housed in a robust metal enclosure with high ingress protection, the WL24-2V240 addresses detection challenges in harsh, dusty, or vibration-prone applications.
Designed for demanding automation tasks, the SICK WL24-2V240 provides dependable performance in logistics, conveyor systems, and manufacturing lines. The built-in polarization filter improves detection reliability when working with reflective or glossy targets, while front screen heating helps maintain accuracy in cold or humid conditions. Adjustable time delay functions reduce false signals from fast-moving or uneven objects, improving process stability. With fast response behavior and durable construction, this sensor supports continuous operation, reduces downtime, and delivers consistent detection in high-throughput industrial workflows.
Why SICK WL24-2V240?
The SICK WL24-2V240 is chosen when long-distance, high-stability detection is non-negotiable. Its retro-reflective design with a dual-lens optical system delivers consistent performance even when alignment conditions are less than ideal. The sensor adapts easily to different control systems through selectable PNP/NPN and light/dark switching, reducing commissioning time. Built with a rugged metal housing and designed for continuous operation, it is a dependable solution for engineers who need accuracy, durability, and predictable behavior in demanding industrial automation environments.
What problem does it solve?
The SICK WL24-2V240 solves unreliable object detection caused by dust, vibration, reflective surfaces, and long sensing distances. In many industrial lines, standard sensors struggle with false switching, signal dropouts, or environmental interference. This model addresses those issues through stable optics, polarization filtering, and adjustable time delays that smooth detection of fast or irregular objects. It ensures consistent presence detection, minimizes unplanned downtime, and helps maintain process flow in logistics, conveyor systems, and automated production lines.
