Discrete shells (exposed on the parallel faces inside the device throat) are either IR transmissive plastic for applications where aperture contamination may occur or opaque plastic with aperture openings for maximum protection against ambient light.

(2) RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering. (3) All parameters tested using pulse technique. (4) Lead spacing of 0.220" (5.59 mm) or 0.320" (8.13 mm) is available. Leads are 0.20" sq. (5.08 mm) and 0.425" (10.80 mm) long (min). (5) Methanol and isopropanol are recommended as cleaning agents. Plastic housings are soluble in chlorinated hydrocarbons and ketones. (6) Polarity is denoted by color of housing top: LED - Gray or Clear Sensor - Black Replaces/Upgrades OPB860, OPB870 Series Optek Technology, Inc. 1215 W.
