The Sick WTB4SC-3P2232A00 Photoelectric Sensor operates on a photoelectric proximity detection principle with refined background suppression, allowing it to differentiate between target objects and reflective backgrounds within a sensing range of 10 mm to 120 mm. Its PinPoint LED generates a sharp, visible red light beam with a 650 nm wavelength, forming a 2.5 mm light spot at 50 mm distance. This ensures highly accurate detection of small or low-contrast parts even in dynamic production environments. Setup is simplified using a single teach-in button or IO-Link, making it easier for technicians to calibrate and deploy across multiple lines.
With a wide input range of 10 V DC to 30 V DC and a low power consumption of 30 mA, this PNP-output sensor supports both light and dark switching modes, providing flexible logic integration. Its ultra-fast 150 Β΅s response time and 1,000 Hz switching frequency make it suitable for high-speed conveyor systems or pick-and-place machines. Built into a slim rectangular ABS housing with dimensions of 12.2 mm Γ 41.8 mm Γ 17.3 mm, the device features a rugged M8 4-pin male connector for reliable communication. The IP66 and IP67 enclosure rating ensures protection against dust, water jets, and temporary submersion, allowing operation in harsh industrial environments from β40 Β°C to +60 Β°C.
Trusted by system integrators and plant engineers alike, the WTB4SC-3P2232A00 offers a strong balance between detection precision, durability, and ease of use. Whether itβs mounted in packaging lines, electronic component assembly, or material handling units, this Sick Photoelectric Sensor delivers consistent performance with minimal maintenance.
