It switches a PNP output at 100 mA, with a 500 µs response time, making it suited for precise object detection on high-speed packaging or assembly lines. The laser spot gives a defined detection zone from 25 mm out to 300 mm, with background suppression meaning it ignores objects beyond that cutoff — useful for sensing on conveyors where the belt or a backstop must not trigger the sensor. Rated IP66, IP67, and IP69K, the housing withstands high-pressure washdown and temporary submersion, so it can be mounted directly on a filling line or in a washdown zone without a protective enclosure. The 300 mm sensing distance with background suppression is the headline spec: it detects a target at up to 300 mm while ignoring reflective surfaces behind that point. The 25 mm minimum sensing distance means the target must be at least 25 mm from the sensor face for reliable detection. The 500 µs response time (ON and OFF) means the sensor can detect objects passing at high line speeds — roughly 300 m/min for a 2.5 mm target — without missing a pulse. Operating voltage is 10–30 VDC, and the PNP output sinks up to 100 mA, enough to drive a PLC input directly or a small relay. The M12 4-pin connector is standard for industrial sensors; the pinout matches most M12 male cordsets. The 12.2 mm wide housing fits into tight mounting rails or alongside other sensors in a multi-sensor bank. Ambient temperature range is -10 °C to +50 °C. No official successor or replacement part number has been issued; this is the active design-in part for the W9 laser background-suppression family.","metaTitle":"SICK WTB9L-3P2461 Photoelectric Proximity Sensor, 300 mm Las","metaDescription":"SICK WTB9L-3P2461 photoelectric proximity sensor with background suppression. 300 mm laser sensing range, PNP output, 500 µs response, IP69K.

The WTB9L-3P2461 uses an M12 4-pin connector, while the WTB4SL-3P2261 uses an M8 4-pin connector. The mounting footprint also differs — the WTB9L is 52.2 mm tall versus 41.8 mm for the WTB4SL. The electrical output (PNP, 100 mA) and sensing range (300 mm) are the same, so the wiring pinout is compatible if you change the cordset, but the mechanical swap is not direct."},{"question":"What is the width and height of the WTB9L-3P2461?","answer":"Width is 12.2 mm, height is 52.2 mm, and length (depth) is 23.6 mm."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/sick/WTB9L-3P2461","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/WTB9L-3P2461 when reusing this data.
