(10.16 mm) lead spacing ? 0.200? (5.08 mm) slot width. 0.250? (6.35 mm) slot depth product photo here rohs 1 3 2 4 description: the opb818 slotted switch consists of an infrared emitting di ode and an npn silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of a 0. 200? (5.080 mm) wide slot. switching of the phototransistor occurs whenever an opaque object passes through the slot. the opb818z is designed for direct soldering into pcbo ards or for mounting in standard dual-in-line sockets and has an 0.25? (6.35 mm) deep and 0.20? (5.08 mm) wide slot. the apertures are 0.06? (1.52 mm) in diameter on both the sensor side (?s?) as well as on the emitter side (?e?). custom electrical, wire and cabling and connectors are ava ilable. contact your local representative or optek for more information. ordering information opb818 slotted optical switch (mounts directly to pcboards or to dual-in-line socket) part number description applications: ? non-contact object sensing ? assembly line automation ? machine automation ? equipment security ? machine safety dimensions are in: inches [ millimeters] pin # description pin # description 1 anode 3 collector 2 cathode 4 emitter
