S51-PA-5-C10-PK

The S51 series Photoelectric Sensor with a wide range of functions and operating distances. S51 sensors are available with either axial or radial 90° optics. In both cases, the optic head and lenses do not project beyond the external 18mm diameter of the sensor housing. The diffuse-proximity model has a 10cm fixed operating range with a wide emission spectrum. Also available is a version with a 1 to 40cm adjustable operating range. Standard retro-reflective models have an operating range up to 4m. The polarized retro-reflective models, used for reliable detection of reflective objects, are fitted with a sensitivity adjustment and have a 3.5m operating range. The through-beam models, used for longer operating distances, reach 18 meters. The S51 sensors provide a 3-wire connection configuration in compliance with the EN60947-5-2 standard. The normally open output is activated in light mode in proximity models and in dark mode in retro-reflective models.
