Its 12.5 mm fixed sensing distance means it catches high-contrast marks at a consistent standoff — no adjustment needed, which simplifies setup on a conveyor rail. The RGB LED light source lets it detect color marks independent of hue, so a single sensor handles black-on-white, red-on-silver, or yellow-on-clear without swapping heads. The 32 µs response time is the key spec for high-speed lines: it resolves marks passing at up to roughly 15 m/s (assuming a 0.5 mm mark), so it keeps up with fast-moving webs or bottles without missing a trigger. The PNP output (50 mA load current) switches directly into a sinking PLC input — no pull-up resistor needed. Operating voltage is 12–24 VDC, so it runs off standard machine supplies. The M8 4-pin male connector keeps wiring clean; no pigtail to dress. Switching is selectable Light / Dark ON via the teach-in, so you can set it to fire on the mark or the background. ## Integration notes At 12 mm wide, 32 mm tall, and 21 mm deep, the KTM-WP11181P fits tight spots on a bracket or DIN-rail mount. The M8 connector points downward in a typical vertical mount, so leave clearance for the cable bend radius.","metaTitle":"KTM-WP11181P Contrast Sensor, 12.5 mm, RGB LED, PNP","metaDescription":"KTM-WP11181P optical contrast sensor, PNP output, 12.5 mm range, 32 µs response, RGB LED, IP67, M8 connector.

The WL9L-3P2232 is a retro-reflective laser sensor with a 12 m range, far longer than the KTM's 12.5 mm. Neither is a direct drop-in for contrast mark detection; the KTM-WP11181P is purpose-built for short-range contrast sensing with RGB flexibility."},{"question":"What are the key dimensions of the KTM-WP11181P?","answer":"Width is 12 mm, height is 32 mm, and length is 21 mm. The M8 male connector adds about 10 mm to the overall depth."},{"question":"Will the KTM-WP11181P drop into a panel specified around the WL9L-3P2232?","answer":"No — the WL9L-3P2232 is 12.2 mm wide but 49.8 mm tall, and it uses a retro-reflective laser with a 12 m range. The KTM-WP11181P is shorter (32 mm) and has a fixed 12.5 mm sensing distance. Wiring is similar (M8 4-pin, PNP), but the mounting bracket and sensing approach differ."},{"question":"What compliance documentation is available for the KTM-WP11181P?","answer":"The evidence does not list specific compliance documents (RoHS, REACH, UL, IEC). Standard SICK documentation for the KTM series typically includes a declaration of conformity and operating instructions; request these with your RFQ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/sick/KTM-WP11181P","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/sick/KTM-WP11181P when reusing this data.
