Optical Switch
Jan 1, 2011 — To provide machine and automation design engineers with a reliable means of noncontact interruptive object sensing, TT electronics Optek Technology has developed a low-profile switch designed with a wider slot to accommodate more applications. The OPB200, an optically triggered switch, contains an 890-nm IR LED and a phototransistor paired in an opaque plastic housing. With its wider sensing gap and lower board-mounted profile, it is suitable for most types of machine automation circuits,...
