fea tures focused for maximum sensitivity 0.5? (12.7mm) sensing distance panel mount choice of output configurations 18? minimum wire length de scrip tion the opb715 series reflective assembly consists of a gaaias led and a photologic a sensor enclosed in an ir transmissive housing. the sensor is characterized to detect paper at 0.5? (12.7 mm). however, the opb715 has a wide operating distance range and is capable of detecting reflective objects at longer distances. even low reflectance materials can be detected at shorter distances. the sensor?s panel-mount plastic housing shields stray light and is terminated with 18? wire leads. the output can be specified as either ttl totem-pole or tll open-collector in buffer or inverter polarity. the led is current limited internally for design convenience. ab so lute maxi mum rat ings (t a = 25 o c un less oth er wise noted) sup ply volt age, v cc (not to ex ceed 2 sec .) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10 v stor age tem pera ture range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 o c to +85 o c op er at ing tem pera ture range . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 o c to +85 o c power dis si pa tion . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 300 mw (1) out put volt age (open-col lec tor only) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35 v notes: (1) der ate line arly at 5.00 mw/ o c above 25 o c.
