SICK WTB4S-3P2132 Photoelectric Sensor Background Suppression

SICK WTB4S-3P2132 is a compact, block‑style photoelectric proximity sensor with background suppression designed for reliable detection in cluttered environments, housed in a 12.2 × 41.8 × 17.3 mm rectangular package. It delivers a 4–120 mm sensing range (optimized for targets with 90% reflectance per DIN 5033) using a 650 nm PinPoint LED with a small Ø2.5 mm light spot at 50 mm to aid quick alignment, and it relies on PinPoint LED technology for clear signaling. Power is 10–30 V DC with ripple < 5 Vpp, drawing ≤20 mA, and it provides a PNP output rated up to 100 mA with light‑switching operation; teaching and adjustment are flexible via a single pushbutton, a 5‑turn potentiometer cable, or IO‑Link, making it suitable for conveyor and packaging applications where background interference or ambient light could cause misdetections. The device is defined as part number 1042053 and emphasizes best‑in‑class background suppression to improve uptime and accuracy in automated systems, including robotics, packaging lines, and other industrial sensing tasks.
