H21A1 Slotted Optical Sensor

H21A1 Slotted Optical Sensor

H21A1 Slotted Optical Sensor

The H21A1 consist of a gallium arsenide infrared emitting diode coupled with a silicon phototransistor in a plastic housing. The packaging 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” to an “OFF” state


• Wide gap between light emitter and detector (3.1mm).

• High sensing accuracy.

• PWB mounting type package.

• Opaque housing.

• 0.035” apertures.

• High Ic(on)
