Description
The CNY65Exi consists of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4-lead plastic package.
The single components are mounted in opposite one another, providing a distance between input and output for highest safety requirements of > 3 mm.
FEATUREs
● Suitable for intrinsic safety circuits according to test certificate No. Ex-81/2158 of PTB
● Isolation material according to UL94 – VO – flammability class
● Low temperature coefficient of CTR
● Creepage current resistance of isolation material according to VDE 0303/DIN 53480: KC ≥ 475
● Isolation test voltage 11.6 kV
● Test class 25/100/21 DIN 40045
● Very low coupling capacity of typical 0.3 pF therefore high noise voltage resistant
● Current Transfer Ratio (CTR) = 50 to 300%
● Coupling System J
