S2 Penta High-Sensitivity Sensors
ULP S2 PCI/V HS
The Universal LightProbe S2 Penta High Sensitivity Sensor features the same popular built-in color binning as the regular S2 Penta Sensor, and is designed test extremely dim LEDs, providing an analog output for intensity, ranging from 0 to 4 volts, corresponding to the LED’s luminous intensity in millicandelas. Implemented in a unique and customizable 2-Part solution, the S2 Penta High Sensitivity 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.)Sensor Size: 0.560 in. dia x 1.38 in. longTypical response times: <1.2s color & intensity outputs simultaneously (the brighter the LED, the shorter theresponse time)Fiber-Optic Probes: Wide Aperture Fiber-Optic Probe recommended

Isolation Amplifier Digital Output
This coupler is an optically coupled isolation amplifier that uses an IC with a high-accuracy sigma-delta A/D converter and a GaAIAs light-emitting diode with high-speed response and high luminance efficiency on the input side, and an IC with a digital signal (MDAT, MCLK) output function on the output side. This coupler is designed specifically for high common mode transient immunity (CMTI) and high linearity (nonlinearity) applications, making it ideal for current sensing in motor drives.

Goniophotometer
GMS2000
In this goniophotometer, the tested luminaire rotates in the prescribed burning position and around the vertical axle and a reflecting mirror rotates around the horizontal axle, meanwhile, a synchronous axle will rotate toward the opposite direction synchronously. The combined motion of the luminaire and mirror permit luminous measurement at the direction of any horizontal or vertical angle without tilting the luminaire, therefore, the luminous intensity will be not variation. The photometer head located at a fixed position of the limiting photomet- ric distance in front of the reflecting mirror to gather the light in each direction.
