S2 Spectra Sensors
ULP-S2 WBI/V
LED Sensor
The ULP S2 Spectra Sensor tests for LED intensity, and for any color in the visual spectrum, plus white. The S2 Spectra Sensor is well-suited for the test of “boundary” color LEDs, as it can unambiguously and repeatedly distinguish between not only adjacent visual colors such as green and yellow, but it can determine different hues of the same color such as yellow and amber, regardless of LED intensity. Implemented in a unique and customizable 2-Part solution, the S2 Spectra Sensor is assembled with your choice of Fiber-Optic Probe, including for the test of densely-spaced LEDs, bright LEDs, dim or misaligned LEDs, right-angle LEDs, and more, including the popular “Trident” Fiber-Optic Probes to sequentially test 3 LEDs with a single Sensor.Operating temperature range: 0oC to 70oCPower consumption: Operates between +5 and 28 volts D.C., at 6mA max. Less than 4.75 volts is not recommendedVoltage protection: Withstands up to +40 volts, & reverse polarity to -18 voltsOutput Pins: 4 gold-plated standard wire-wrap pins (0.025 in. sq.)Output Loads: ‘Int.’& ‘Color’- 2Kohms min., 100pF max.Sensor Size: 0.560 in. dia x 1.38 in. long.Typical response time: Typical response time: <10mS capture time; <100mS overall response timefor color and intensity simultaneouslyFiber-Optic Probes: Can be paired with any Universal LightProbe Fiber-Optic Probe
