The Wenglor OLDK503A0002 is a universal retro-reflective sensor operating with red light and requiring a reflector. It reliably detects objects with glossy or reflective surfaces at high speeds. Thanks to its long detection range, it is ideal for applications including feed and presence control as well as detecting items on wide conveyor belts. With IO‑Link 1.1 support, users can configure PNP/NPN outputs, NC/NO settings, detection distance, status, and signal values. Its compact design and integrated mounting technology allow installation even in tight spaces.
