PHOTOTRANSISTOR

OPTICAL INTERRUPTER SWITCH

DESCRIPTION

PACKAGE DIMENSIONS

The H21A1, H21A2 and H21A3 consist of a

gallium arsenide infrared emitting diode

coupled with a silicon phototransistor in a

plastic housing. The packaging system is

NOTES:

1. Derate power dissipation linearly 1.33 mW/°C above 25°C.

2. RMA flux is recommended.

3. Methanol or isopropyl alcohols are recommended as cleaning

agents.

1. Dimensions for all drawings are in inches (mm).

2. Tolerance of ± .010 (.25) on all non-nominal dimensions

unless otherwise specified.

4. Soldering iron tip 1/16” (1.6mm) minimum from housing.

(T = 25°C unless otherwise specified)
