OPB706B

 Choice of Phototransistor (OPB706) or Photodarlington (OPB707) output  Unfocused for sensing diffuse surface  Low cost plastic housing  Designed for use with PCBoards or connectors The OPB706 consists of an infrared Light Emitting Diode (LED) and an NPN silicon Phototransistor mounted “side-by-side” on parallel axes in a black plastic housing. The OPB707 consists of an infrared LED and an NPN silicon Photodarlington mounted “side-by-side” on parallel axes in a black plastic housing. On both OPB706 and OPB707, the LED and Phototransistor / Photodarlington are molded using dark infrared transmissive plastic to reduce ambient light noise. The Phototransistor / Photodarlington responds to light from the emitter when a reflective object passes within its field of view of the device. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.       Part Number Non-contact reflective object sensor Assembly line automation Machine automation Machine safety End of travel sensor Door sensor OPB706A OPB706B OPB706C OPB707A OPB707B OPB707C LED Peak Wavelength Sensor Reflection Distance Lead Length / Spacing 0.050" (1.27mm) 0.45" / 0.087", 0.100" Transistor 935 nm Darlington OPB706 3 1 4 2 OPB707 [ MILLIMETERS] DIMENSIONS ARE IN: RoHS 3 1 4 2 INCHES Pin # LED Pin # Transistor 3 4 Anode Cathode 1 2 Collector Emitter Storage and Operating Temperature Range Lead Soldering Temperature [1/16 inch (1.6mm) from the case for 5 sec. with soldering iron] -40° C to +85° C (1) 260° C Input Diode Forward DC Current 50 mA Peak Forward Current (1 µs pulse width, 300 pps) 3A Reverse DC Voltage 2V (2) 75 mW Power Dissipation Output Phototransistor (OPB706) | Output Photodarlington (OPB707) Collector-Emitter Voltage OPB706 OPB707 24 V 15 V Emitter-Collector Voltage 5V Collector DC Current OPB706 OPB707 Power Dissipation OPB706(2) OPB707(3) Notes: (1) RMA flux is recommended.
