When customers have an application requiring a sensor with reliable long distance sensing in unforgiving environments, look no further than the new heavy duty SA1U photoelectric sensors from IDEC! These high-quality photoelectric sensors are offered in four sensing modes: throughbeam, background suppression, diffuse and polarized retro reflective. Long distance sensing ranges as far as 50 meters with through-beam models and as close as 1 meter with diffuse models. They also support 12-240V DC and 24-240V AC, a much wider range of power at a great low price compared to most competitor sensors.SA1U sensors utilize a spring up screw terminal making wiring easy. Customers can use almost any conductors and no special cables (M8 or M12) are required. These switches are assembled in a fully automated robotic process and are UL/c-UL listed, CE marked and IP67 rated, making them ideal for use in wet environments such as bottling and food processing industries. SA1U is also perfect for direct sunlight applications.
