The visible red PinPoint LED makes alignment straightforward on a conveyor or pick-and-place station. PNP light-ON output switches at 400 µs, fast enough for counting small parts at moderate line speeds. The 7.7 mm wide housing fits tight spots on a DIN rail or machine frame where every millimeter of panel space is accounted for. The 18 mm sensing distance is the maximum range to a white 90% reflective target; real-world range drops with dark or matte surfaces, so the 1 mm minimum gives you a usable window for glossy black parts or shiny metal. Background suppression means the sensor ignores objects beyond the set distance — no false triggers from a machine frame or a passing hand behind the target zone. The 400 µs response time translates to detecting a 10 mm part moving past at roughly 25 m/s before the output misses it. ## Panel and wiring fit The 7.7 mm wide body is the narrowest in the W2S-2 family. On a DIN rail, it occupies a single slot pitch, leaving room for additional sensors or a terminal block in a crowded enclosure. The 200 mm pigtail with an M8 3-pin connector reaches a nearby junction box or a pre-wired M8 splitter; if the cable is too short, an M8 extension cord adds length without re-terminating.","metaTitle":"SICK WTB2S-2P3110 Photoelectric Proximity Sensor, 18 mm, PNP","metaDescription":"SICK WTB2S-2P3110 photoelectric proximity sensor with background suppression. 18 mm sensing range, PNP output, 400 µs response, IP67.

It shares the same 7.7 mm width, PNP output, and IP67 rating, but its sensing range extends to 66 mm (versus 18 mm) and its response time is 500 µs instead of 400 µs. The WTB2S-2P3110 uses a 200 mm cable with M8 connector, while the WTB2S-2P3160 has a bare M8 3-pin connector. For a panel already wired with an M8 receptacle, the WTB2S-2P3160 drops in without rewiring; the WTB2S-2P3110 requires the cable pigtail to be routed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/sick/WTB2S-2P3110","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/WTB2S-2P3110 when reusing this data.
