General Note

TT Electronics reserves the right to make changes in product specicaon without

noce or liability. All informaon is subject to TT Electronics’ own data and is

considered accurate at me of going to print.

Descripon:

Each device in this series is a high intensity gallium aluminum arsenide infrared eming diode that is suited for use as a

PCBoard mounted sloed switch or an easy mount PCBoard interrupter.

Each dome lens OP240 and OP245 device is an 890 nm diode that is molded in an IR-transmissive clear epoxy side-looking

package. OP240 is mechanically and spectrally matched to the OP550 and OP560 series of phototransistors. OP245 is

mechanically and spectrally matched to the OP555 and OP565 series devices.

Please refer to Applicaon Bullens 208 and 210 for addional design informaon and reliability (degradaon) data.

Applicaons:

 Space-limited applicaons

 PCBoard mounted sloed switch

 PCBoard interrupter

Features:

 Wide irradiance paern

 Side-looking package for space-limited applicaons

 Wavelength matched to silicon’s peak response

 Mechanically and spectrally matched to other OPTEK products

OP245 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 plascs.
