 Unfocused for sensing diffuse surfaces  Uses lensed devices for collimation of light beam  Low-cost plastic housing  Compact surface mount package 0.300” x 0.160” x 0.114” [7.6mmx4.1mmx2.9mm]  Typical peak emission wavelength 890nm  Reduced visible ambient light sensitivity  Optimal operating distance range 0.4” [10.2mm] to 1.0” [25.4mm] 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 black plastic housing. The Phototransistor is molded 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. 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.

Soldering should not exceed this curve in temperature and time.  Avoid soldering more than once.  Avoid exerting any type of pressure on the optical lenses and contact leads before, during, and after soldering. Storage:  Storage temperature and relative humidity (R.H.) conditions are: 5°C to 30°C and 70% R.H. or less.  Moisture proof bag should be open only if devices are ready to be used. Devices should be utilized within 72 hours after package has been opened.  After opening the package, devices should be kept at a temperature of 5°C to 30°C and 60% R.H. or less.  If the devices have exceed the storage time or the humidity card indicates 60% relative humidity level, all devices should go through a baking treatment outside the original package prior to usage. Baking treatment: 60°C +/- 5°C for 24 hours. Tape and Reel package dimensions: Notes: 1. * 10 sprocket hole pitch cumulative tolerance +/- 0.2mm. 2. ** Pocket position relative to sprocket hole measured as true position of pocket, not pocket hole. 3.
