fea tures 0.125" (3.18 mm) wide gap choice of aperture choice of opaque or ir transmissive shell material choice of mounting configuration choice of lead spacing de scrip tion the opb360/370 series of slotted switches provides the design engineer with the flexibility of a custom device from a standard product line. building from a standard housing with a .125" (3.18 mm) wide slot, the user can specify (1) electrical output parameters, (2) mounting tab configuration, (3) choice of lead spacing, (4) discrete shell material, and (5) aperture width. all housings are an opaque grade of injection-molded plastic to minimize the assembly's sensitivity to ambient radiation, both visible and near-infrared. 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. re places/up grades opb860, opb870 series ab so lute maxi mum rat ings (t a = 25 o c un less oth er wise noted) stor age and op er at ing tem pera ture range . . . . . . . . . . . . . . . . . . . . . . . . -40 o c to +85 o c lead sol der ing tem pera ture range [1/16 inch (1.6 mm) from case for 5 sec. with sol der ing iron] . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 240 o c (2) in put di ode for ward dc cur rent . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 50 ma peak for ward cur rent (1 m s pulse width, 300 pps) . . . . . . . . . . . . . . . . . . . . . . . 3.0 a re verse dc volt age . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2.0 v power dis si pa tion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 mw (1) out put pho to tran sis tor collector- emitter volt age . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30 v emitter- collector volt age . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5.0 v col lec tor dc cur rent . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30 ma power dis si pa tion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100 mw (1) notes: (1) derate linearly 1.67 mw/ o c above 25 o c.
