NTE3100
Photon Coupled Interrupter Module
Description:
The NTE3100 Interrupter Module is a gallium arsenide infrared emitting diode coupled to a silicon
phototransistor on a plastic housing. The package system is designed to optimize the mechanical
resolution, coupling efficiency, ambient light rejection, cost, and reliability. The gap in the housing provides a means of interrupting the signal with an opaque material, switching the output from an “ON”
into an “OFF” state.
