SICK AL20E-PM334S04 Array Sensor

The SICK AL20E-PM334S04 Array Sensor delivers precise edge-detection of reflector targets in a compact AX20 housing (24.3 mm wide x 59.8 mm high x 54.1 mm deep) with a sensing distance up to 100 mm and a working range of 90–110 mm. As part of the AX20 family, it uses white LED illumination (400–700 nm) and provides both a PNP switching output and a 4–20 mA analog output with 12‑bit resolution, powered from 24 V DC and consuming ≤ 3.1 W. Optical specifications include a light spot of 50 × 10 mm, a minimum detectable object of 1.6 mm, repeatability of 0.05 mm, and linearity within ±2% over the specified sensing range, with reliable operation across the 90–110 mm band. Designed for edge-detection on reflector targets, this sensor is suitable for alignment, positioning, and quality-control tasks on packaging lines, conveyors, and other automated systems that require precise edge sensing. Its compact form and integrated sensing capabilities make it a practical solution for upgrading product flows where reflector-edge detection drives automation.
