Product type | IC(ON) (mA) min | Test Conditions | Output | Aperture Width (mm) |
H22A1 | 1.0 | If=20mA, VCE = 5V | Phototransistor | 0.94 |
H22A2 | 2.0 | If=20mA, VCE = 5V | Phototransistor | 0.94 |
H22A3 | 4.0 | If=20mA, VCE = 5V | Phototransistor | 0.94 |
The H22AX products consist of a infrared light emitting diode coupled to an NPN silicon phototransistor packaged in a injection molded housing. The package is designed to optimize the mechanical resolution, coupling efficiency, ambient light rejection, and reliability. Inserting/removing an opaque material into the gap when the LED is operating, switches the transistor on/off.
