Request InfoOptek Technology, Industrial Sensing & ControlTo 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, especially for assembly line automation and machine safety/security applications.
