Description:

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

PCBoard mounted slotted 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 Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.

Applications:

 Space-limited applications

 PCBoard mounted slotted switch

 PCBoard interrupter

Features:

 Wide irradiance pattern

 Side-looking package for space-limited applications

 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 plastics.
