Product Description
SICK WTB4SL-3P1161 Background Suppression Photoelectric Sensor is a high-performance block sensor designed for precise object detection in industrial automation applications. Operating over a detection range from 25 mm to 300 mm, this sensor employs a red laser light source with advanced background suppression technology to minimize false signals caused by reflective or ambient light interference.
The sensor features a robust plastic housing rated IP66 and IP67, ensuring reliable operation in harsh environments with dust and water exposure. It operates within a temperature range of -10°C to 50°C and supports a maximum DC voltage of 30V with a current rating up to 100mA. A fast response time of 500 microseconds enables timely feedback for demanding process controls.
This model includes a PNP output with a 4-wire terminal configuration and offers flexibility via a teach-in pushbutton that optimizes detection for both transparent and opaque objects. With CE and UL certifications, the WTB4SL-3P1161 meets international safety and quality standards.
Typical industrial applications include overhang control to detect panel positions, precise object positioning for quality control, edge detection in glass manufacturing, monitoring boreholes, and robotic gripper presence checks. It is suitable for sectors such as manufacturing, automation, robotics, and quality assurance laboratories.
Precise laser light spot for accurate switching behavior and minimized incorrect switching. High optical ambient light immunity reduces machine downtime. Background suppression technology eliminates undesired reflective interference.
Compact block sensor form factor with IP66/IP67 protection. Flexible detection of transparent and non-transparent materials. Reliable operation in industrial environments with wide operating temperatures. Useful for diverse industrial applications including robotics and manufacturing inspection.
Simple adjustment with teach-in button or optional IO-Link interface for diagnostics. Explore the full range of sensors and automation equipment to enhance your industrial solutions on EnvMart.
