OP240C

Plastic Infrared Emitting Diode OP240 Series OP245 Series 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 OP240 OP245 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 Part Number OP240A OP240B OP240C OP240D OP245A OP245B OP245C OP245D Ordering Information LED Peak Wavelength Lens Type Dome 890 nm Recessed 40° 0.50" minimum Total Beam Angle Lead Length OP240 (A, B, C, D) 1 2 Pin # DIMENSIONS ARE IN: [MILLIMETERS] INCHES LED Cathode Anode 1 2 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. RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.

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. OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
