DESCRIPTION

The CNY651 Series are high isolation voltage TH and SMD

version optocouplers consist of a phototransistor optically

coupled to a gallium arsenide infrared-emitting diode in a

4 pin plastic package.

The single components are mounted opposite one another,

providing a distance between input and output for highest

safety requirements of > 3 mm.

VDE STANDARDS

These couplers perform safety functions according to the

following equipment standards:

• DIN EN 60747-5-5 (VDE 0884-5)
