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.

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. E
E(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. E
E(APT)
is not necessarily
uniform within the measured area.
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
