Optical Switch

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, especially for assembly line automation and machine safety/security applications. When no object is present in the slot, the output phototransistor conducts current to maintain the circuit. When an object enters the slot and blocks the beam of IR light from the LED, the output switches to the “off” state to interrupt the circuit.
