Description:

The OPB733TR 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 grey plastic housing. The Phototransistor is molded in a grey 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. The OPB733TR sensors are packaged in 16mm tape on 7” [178mm] diameter reels, 500 pcs per reel. Tape and Reel package compatible with most automatic placement equipment.

Custom electrical, PCB assembly, wire and connectors are available. Contact your local OPTEK authorized representative or OPTEK for more information.
