Using push-button programming, Carlo Gavazzi’s PD30 Series photoelectric sensors allow remote teaching options in most models, so setup and programming of the sensor can be done away from the application. These same models also provide an option for locking the sensor settings. A muting version exhibits mutual interference protection, sensor alignment aid, and the ability to verify the sensor’s proper operation remotely via a PLC. A dust alarm output signals an alarm when the sensor lens needs to be cleaned. The 10.8-mm × 20-mm × 30-mm series presents models with 15-m through beam, 6-m polarized retroreflective, diffuse reflective, background suppression, retroreflective, and transparent object detection. Each cUL/RoHS/CE-approved sensor is powered by 10 VDC to 30 VDC, and have a 100-mA transistor output, which can be programmed as normally open or normally closed. From $70.
