SICK WS/WE45-P260S01 High-Temperature Photoelectric Sensor

The Applications for High-Temperature Long-Range Detection

1. Reliable Hot Billet Detection in Steel Rolling Mills

In steel rolling mills, red-hot billets leave reheating furnaces and travel at high speed toward rolling or cutting stations. Radiant heat, scale particles, and long mounting distances often cause unstable detection with standard sensors. The SICK WS/WE45-P260S01 overcomes these challenges by using a through-beam principle that maintains a strong, uninterrupted signal across wide gaps. Its ability to detect objects above 800 °C ensures consistent performance despite intense heat. Adjustable sensitivity and delay functions help ignore sparks and brief obstructions, allowing accurate billet tracking, precise process timing, and safer operation of downstream equipment.

2. Glass Sheet Presence Monitoring After Furnace Exit

In glass production lines, sheets emerge from furnaces while still extremely hot and move along long conveyor paths toward inspection or cutting areas. Heat radiation, reflections, and airborne particles can interfere with conventional detection methods. The WS/WE45-P260S01 provides stable presence detection by separating the emitter and receiver, reducing sensitivity to surface reflectivity. Its long sensing range supports wide conveyor layouts, while the rugged housing withstands harsh thermal conditions. Reliable detection of hot glass sheets improves synchronization between production stages, reduces handling errors, and supports consistent quality in continuous glass manufacturing processes.

3. Slab Transfer Detection in Continuous Casting Lines

Continuous casting operations rely on precise monitoring of hot slabs as they move between casting, cooling, and cutting zones. Steam, vibration, and high ambient temperatures frequently lead to false signals or missed detections. The SICK WS/WE45-P260S01 delivers dependable performance through its high signal stability and long-range capability. Adjustable time-delay settings allow the sensor to ignore temporary visual disturbances such as steam clouds. This ensures accurate slab position feedback for automation systems, helping prevent collisions, reduce downtime, and maintain safe, uninterrupted steel production.

4. Red-Hot Forged Part Detection on Automated Conveyors

Forging and heat-treatment facilities transport glowing components between presses, furnaces, and cooling stations using automated conveyors. These environments combine intense heat, debris, and mechanical vibration, which challenge standard sensors. The WS/WE45-P260S01 is designed to operate reliably under such conditions, offering consistent detection of red-hot parts without being affected by radiant surfaces. Its durable metal housing and adjustable sensitivity allow adaptation to varying part sizes and layouts. Accurate part detection helps prevent conveyor jams, supports robotic handling accuracy, and improves overall production efficiency in forging operations.
