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]
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 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.
Applications:
• Assembly line automation
• ATM (Card Reader, Receipt Dispenser)
• Auto-dispense equipment
• Amusement

Notes:
1. “d” is the distance from the assembly’s top surface to the reflective surface.
2. Measured using Eastman Kodak neutral white test card with 90% diffuse reflectance as a reflecting surface.
3. By designed but not tested.
4. Methanol or Isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons
and ketones.

Soldering Method:
• Reflow soldering profile shown below. 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.
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
