The RiKO PK5 Series consists of micro‑sized flat photoelectric sensors designed for narrow‑space object detection in industrial automation and control systems. These sensors feature an ultra‑slim body that makes them easy to mount in tight spaces while still offering reliable detection capabilities. All PK5 models operate on a DC 12 – 24 V supply and include protection circuits that guard against reverse polarity and output short circuits. The sensors are well‑suited for detecting small parts on conveyors, positioning verification, and proximity sensing in compact applications.
Within this lineup, PK5‑DU03N is a diffuse‑reflection sensor for very short range detection. The PK5‑1N and PK5‑1N2 are through‑beam type sensors capable of detecting objects over longer distances up to around 1 m, using paired emitter and receiver units. Models may have NPN or PNP output options depending on the suffix used.
