Description
The SICK W27 Series Photoelectric Sensor has three base system configurations, including proximity sensor, though-beam sensor, and retro-reflective sensor. These models utilize PinPoint LED or LED light sources, with visible red or infrared light types. Sensing range minimums are as low as 0m, and can reach a maximum of 45m, depending on sensor type. Light, dark, or light/dark switching modes are available, with NPN, PNP, or relay outputs. Durable housing ensures a long service life, with ATEX-rated variants that meet Category 3G/3D requirements for use in Zone 2 and 22 explosive areas (dependent on configuration).
