| VAC54 MINIATURE CADMIUM SULPHIDE PHOTOCONDUCTIVE CELL LIGHT DEPENDENT RESISTOR 34 2.4 FEATURES Miniature open frame package. Epoxy coated. Moisture resistant. Spectral response similar to the human eye. Applications include dusk - dawn lighting control. Dimensions in millimetres O 0.5 4.3 3.4 5.1 SPECIFICATION AND PERFORMANCE Model Vmax (VDC) Pmax (mW) Ambient Temp (C) Light Spectral Resistance Dark Peak at 10 lux Resistance (nm) (M) (k) Gamma Char. 100 T 10 Response Time (ms) Rise Time Decay Time VAC54 150 100 -30 ~ +80 590 50 ~ 140 20 0.7 20 30 Measuring Conditions 1. Light Resistance: measured at 10 lux with standard light A (2854k color temperature) and 2h pre-illumination at 400-600 lux prior to testing. Dark Resistance: measured 10 seconds after pulsed 10 lux. Gamma Characteristic: between 10 lux and 100 lux and given by log (R10/R100) T= - log (R10/R100) log (100/10) R10, R100 cell resistance at 10 lux and 100 lux. The error of T is +0.1. 4. 5. Pmax: Max. power dissipation at ambient temperature of 25C. Vmax: Max. voltage in darkness that may be applied to the cell continuously.
