Sick WTB4FP-1G311120ZZZ Photoelectric Sensor

The WTB4FP-1G311120ZZZ Photoelectric Sensor from SICK combines advanced optical detection with robust engineering to meet the exacting needs of industrial automation. At its core, this photoelectric sensor operates using background suppression technology, offering reliable sensing even in challenging environments with reflective or shiny objects. With a sensing range from 4 mm to 220 mm, it accurately detects targets as small as 0.2 mm at a distance of 130 mm, using a focused PinPoint LED and visible red light at 635 nm. The point-shaped light spot (Ø 4.2 mm at 130 mm) ensures pinpoint accuracy during alignment and detection.

The sensor is configured using intuitive Teach-Turn adjustment, which simplifies calibration during commissioning or part changes. With a fast response time of ≤ 500 µs and a switching frequency of 1,000 Hz, this sensor excels in dynamic production lines where milliseconds matter. Its push-pull (PNP/NPN) output allows seamless integration into both sourcing and sinking input systems, while the output current capacity of 100 mA and low power consumption of ≤ 25 mA enhance system efficiency. Operating on 10 V DC to 30 V DC with ripple tolerance under 5 Vpp, it's ideal for continuous, reliable use across automation environments.

Built for harsh operating conditions, the SICK WTB4FP-1G311120ZZZ features a flat rectangular housing (16 mm x 40.1 mm x 12.1 mm) made from tough VISTAL® plastic, with a PMMA front screen offering excellent optical clarity and resistance. With IP66 and IP67 enclosure ratings, it withstands dust, vibration, and washdowns, making it ideal for both indoor and outdoor use. The sensor is pre-fitted with a 2-meter PVC cable for quick, secure wiring. Capable of handling ambient temperatures from –40 °C to +60 °C, this sensor is widely trusted by automation engineers, OEMs, and system integrators for its performance stability, installation ease, and long-term durability.

The SICK WTB4FP-1G311120ZZZ Photoelectric Sensor is built for precise object detection in fast-paced environments like automated packaging lines, sorting systems, material handling units, and pick-and-place robots. Its compact form factor and background suppression allow it to perform consistently, even in tight spaces and when dealing with glossy, transparent, or curved surfaces.

In a typical conveyor-based packaging plant, this photoelectric sensor can detect box edges, trigger actuators for sealing, or sort items based on presence or absence—without getting affected by labels or reflective wraps. Electronics manufacturers use it to detect tiny PCB boards or components as small as 0.2 mm, while FMCG lines benefit from its stable detection on fast-moving, multicolored packets. Its fast response time of ≤ 500 µs makes it ideal for systems that demand microsecond-level precision.

Indian plant technicians and junior engineers appreciate the WTB4FP-1G311120ZZZ for its easy Teach-Turn adjustment, rugged IP67 build, and wide voltage range compatibility. Whether you're upgrading an old sensor or building a new smart automation setup, this model delivers the balance of speed, stability, and confidence that modern production teams expect from a SICK photoelectric sensor.
