Its 4–220 mm sensing range means it reliably detects objects from a few millimeters out to just under a quarter meter, ignoring the background beyond that point — useful on a conveyor or pick-and-place station where you need to see the part, not the belt or fixture behind it. Light-ON only — the output turns on when the object is present; if your application needs dark-ON (output on when the beam is clear), this part won't do it without an external inversion circuit. Rated IP66/IP67 and the M8 3-pin connector suit it for washdown areas or dusty environments — think food processing, packaging lines, or automotive assembly where hoses are used. The visible red PinPoint LED makes alignment visible to the naked eye; no laser safety precautions needed. ## Integration note — panel and mounting At 16 mm wide, 40 mm tall, and 12 mm deep, this sensor fits tight DIN-rail enclosures or machine frames where every millimeter counts. The M8 3-pin connector means a quick disconnect — no cable gland or stripping needed. Verify the mating connector is wired for push-pull (pinout: brown +V, blue GND, black output); the sensor does not include a mating plug.","metaTitle":"SICK WTB4FP-21311120ZZZ Photoelectric Sensor, Background Sup","metaDescription":"SICK WTB4FP-21311120ZZZ miniature photoelectric proximity sensor with background suppression, 220 mm range, PinPoint LED, IP66/IP67, M8 connector.
