OPB733TR Datasheet, PDF (1/6 Pages) OPTEK Technologies – Unfocused for sensing diffuse surfaces

Reflective Object Sensor
Type OPB733TR
Features:
• 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.
