Featuring default clear object detection mode setting, Model Q4X eliminates 2-point, dynamic, foreground, and background suppression mode. Without requiring retro-reflector, sensor combines window thresholds on both target distance and target reflected intensity. Bright readout on angled 4-digit display enables viewing from multiple vantage points, while FDA-grade stainless steel housing rated to IP67, IP68, or IP69K allows use in wet and high-pressure washdown environments.
