The SICK GL10-R3811S07 is a compact photoelectric retro-reflective sensor from the G10 series. It performs reliable object detection by reflecting its emitted light off a reflector positioned opposite the sensor. Equipped with a PinPoint red LED, a potentiometer adjustment interface, and an SPDT (relay) switching output, this sensor is designed to operate over extended distances and adapt to different environmental conditions. Its robust IP67-rated housing ensures reliable performance in industrial automation and logistics applications.
