PHOTOSWITCH R Photoelectric Sensors

MiniSightt





Description
MiniSight photoelectric sensors offer high performance sensing in a compact package. Available in both DC and universal voltage two-wire AC/DC versions, MiniSight is available in a wide range of sensing modes to provide multiple application solutions in a single housing. These sensors are interchangeable with many otherstandard 18mm threaded barrel photoelectric sensors. Suitable for general purpose applications, these sensors can also be used where rugged performance is required. MiniSight sensors will withstand 1200 psi (8270kPa) high pressure, 60_C (140_F) high temperature washdowns, making them ideal for use in food and beverage packaging and material handling applications. Three indicators display power,output, and operating margin status. Note: The power indicator shuts off when the output indicator turns on. The margin indicator verifies a minimum 2.5X operating margin and flashes if an output is shorted. A clutch-protected five turn sensitivity control allows sensitivity adjustment. All are located under a clear, captive cover that does not require tools for access. MiniSight sensors areavailable in three versions: • 10.8–30V DC standard versions feature response times of 1ms (16ms for transmitted beam), dual NPN/PNP DC outputs and switch selectable light or dark operation. • For high speed applications, 300µs response time versions are also available for 10.8–30V DC operation. • Universal voltage two wire 21.6–250V AC/DC sensors have short-circuit protection across the entire voltagerange.
