DESCRIPTION
The SFH 435 is a two-beam GaAs infrared emitting diode with one chip. The beams emerge diametrically from the diode in a half angle of 8 degrees.
The radiation is emitted in the near infrared range. It is excited by a current flowing in forward direction, dc as well as pulse operation with simultaneous modulation are possible.
The SFH 435 is especially suitable for application in dual photo interrupters, i.e., light reflection switches, tape and control.

Safety Advices
Depending on the mode of operation, these devices emit highly concentrated non visible infrared light which can be hazardous to the human eye. Products which incorporate these devices have to follow the safety precautions given in IEC 60825-1 and IEC 62471.
