Slotted Optical Switch OPB818 Features: Choice of aperture Choice of opaque or IR transmissive shell material Non-contact switching Mounts directly to PCBoard or dual-in-line socket 0.400” (10.16 mm) lead spacing 0.200” (5.08 mm) slot width. 0.250” (6.35 mm) slot depth Product Photo Here Description: The OPB818 slotted switch consists of an infrared emitting diode 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 OPB818 is designed for direct soldering into PCBoards 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 0.033” (0.84 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 available.

Duration can be extended to 10 seconds maximum when flow soldering. Derate linearly 1.67 mW/°C above 25° C. All parameters were tested using pulse techniques. Leads are 0.20” square (5.080 mm) and 0.425” long (10.80 mm), minimum. Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and ketones. Spray and wipe; do not submerge. Polarity is denoted by color of housing top: LED (gray or clear), sensor (black). Do not apply reverse voltage to LED. LED will be a 0V in reverse voltage and draw current as if a short. OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
