Plastic Infrared Emitting Diode

OP240 Series

OP245 Series

Notes:

1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum of 20 grams force

may be applied to the leads when soldering.

2. Derate linearly 1.33 mW/° C above 25° C.

3. EE(APT) is a measurement of the average apertured radiant energy incident upon a sensing area 0.180” (4.57 mm) in diameter

perpendicular to and centered on the mechanical axis of the lens and 0.653” (6.60 mm) from the lens tip. EE(APT) is not necessarily

uniform within the measured area.

CONTAINS POLYSULFONE

To avoid stress cracking, we suggest using

ND Industries’ Vibra-Tite for thread-locking.

Vibra-Tite

evaporates fast without causing structural

failure in OPTEK'S molded plastics.
