The SICK W12 Series Photoelectric Sensor is a versatile product family with highly precise object detection for various industrial applications. Variants include proximity, retro-reflective, and through-beam principles, with each unit offering reliable performance in shock- and vibration-heavy environments thanks to the durable zinc die-cast, or teflon coated housing. The BluePilot LED alignment aid offers quick and efficient commissioning. An optional IO-Link interface not only permits versatile adjustment, but also offers advanced diagnostics including fault detection. Background and foreground suppression ensure high accuracy and detection of transparent or very dark objects, across a spectrum of sensing ranges up to 80m. WTM12L laser-based models offer MultiMode functionality. The MultiMode feature includes configuration options such as two-point teach-in, two independent switching points or window teach-in. The two switching points further expand the versatility of the W12 Series, permitting detection and differentiation between standing and lying objects.
