OPB733TR

OPB733TR is a reflective object sensor consists of an 890nm, infrared light emitting diode (LED) and an NPN silicon phototransistor which are mounted side-by-side on parallel axes in a miniature surface mount black plastic housing. The phototransistor is moulded in a dark epoxy package, which minimizes visible ambient light sensitivity. The phototransistor responds to radiation from the LED when a reflective object passes within its field of view. This unfocused reflective object sensor is ideal for non-contact detection of materials such as paper, labels, white plastic and many other reflective materials. Typical applications are assembly line automation, ATM (card reader, receipt dispenser), auto-dispense equipment, amusement equipment, end-of-travel sensor, door sensor, edge detection, paper jam detection, mark detection, counters and sorters, proximity sensing, medical equipment, machine safety.
