Description
The DADISICK DK-GF18-400J-ZCB is a retroreflective (mirror reflective) photoelectric sensor engineered for reliable, non-contact object detection in demanding industrial environments. With universal AC/DC power supply (12-240V DC / 24-240V AC) and an adjustable sensing distance of 30-4000 mm, it delivers stable performance for conveyor, packaging, and logistics automation where a separate reflector is impractical or space is limited. The retroreflective (mirror reflective) design uses a single device plus a reflector: the emitter and receiver share the housing, and the beam returns from the reflector. An object is detected when it interrupts the returned light. This makes the DK-GF18 ideal for detecting opaque objects at long range without running cables to both sides of the line. Typical applications include conveyor part counting, packaging machine positioning, pallet and carton presence detection, and logistics sorting systems. The drawing below shows the DK-GF18 mechanical dimensions and the retroreflective (mirror reflective) wiring diagram, including the 3-wire connection (brown = V+, blue = 0V, black = output), relay output, and the 2 m PVC cable. Always verify the wiring against your controller before energizing the circuit. Get the full DK-GF18 datasheet with complete electrical characteristics, outline drawings, and wiring details.
