Product Description
The SICK WTB4SL-3P3261 is a background suppression Photoelectric Sensor designed for precise detection tasks in industrial automation. This block sensor employs a laser light spot with laser class 1, enabling accurate detection of objects within a range of 25 mm to 300 mm. Featuring PNP output and protected by IP66 and IP67 ratings, the sensor is well suited for demanding environments.
Equipped with the latest SICK proprietary ASIC and laser technologies, including a second emitter LED, it offers outstanding suppression of background interference and immunity to ambient light, including from modern energy-saving lamps. The sensor's teach-in pushbutton allows switching between transparent and non-transparent object detection, enhancing flexibility.
Applications include overhang control to prevent panel overhang, precise position monitoring for quality checks, edge detection of glass panels, borehole feature inspection, and part verification in robotic grippers.
The sensor's compact and robust plastic housing ensures durability. It operates within a temperature range of -10°C to 50°C and handles a maximum DC voltage of 30V with a max current of 100mA. Certified by CE and UL, it meets safety standards requisite in industrial installations.
Precise laser light spot ensures reliable switching. Strong ambient light immunity reduces incorrect switching. Background suppression eliminates false signals from reflections. Multiple adjustment options including IO-Link for system diagnostics.
Robust plastic housing suitable for harsh conditions. Wide operating temperature range of -10°C to 50°C. Applications span automation tasks in manufacturing and robotics.
Manufactured in Germany, the WTB4SL-3P3261 sensor is an ideal choice for industrial and laboratory automation requiring precise and reliable object detection. Explore related sensors and automation components in the EnvMart Sensors category for comprehensive solutions.
