REFLECTIVE OPTICAL SWITCHES
DESCRIPTION The ISTS149, ISTS703A, ISTS708 each consist 5.
1 of an infrared emitting diode and a
NPN silicon photo
transistor mounted side by side on point of converging axes in a polycarbonate housing.
The optimum response package is designed to optimise the mechanical resolution, coupling efficiency, ambient light rejection, cost and reliability.
The photo
transistor responds to radiation from the emitter only when 3.
