The GB43 series background suppression photoelectric sensors are designed for precision detection in industrial settings. They feature a maximum detection distance of 30-1500mm and a stable detection range of 60-1000mm, making them ideal for detecting small step differences. These sensors operate on 12-24V DC power, have a response time of 2ms, and can handle a switching frequency up to 450Hz. With IP64 protection and reverse polarity protection, they are suitable for use in environments with temperatures ranging from -25°C to +50°C. The GB43 series is unaffected by target or background color, ensuring accurate detection even on production lines with varying workpiece colors.
