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.
