| E2P0062-37-X2 CAPSULE SENSOR This version: Jan. 1998 Previous version: May. 1997 OPU872CP electronic components OPU872CP Capsule Sensor with Light Emitter and Photosensor GENERAL DESCRIPTION The OPU872CP is a capsule sensor which includes both a light emitting diode and a phototransistor in the package with connector. The transmission type photointerruptor is implemented by combining the OPU872CP with a rectangular prism (Option); optically set with face to face. Since the sensor and LED are in one side, compared to the conventional sensor in which a sensor is in opposite side of a LED, the OPU872CP will need only a small wiring space. The capsuled type has the advantages of easy mounting and dustproof construction, so the OPU872CP is best suitable for paper detection sensor applications. FEATURES * * * * Easy mounting No need to use soldering since the connector is built in Small size Superior dustproof APPLICATIONS * Passing object sensor * Position detector 1/9 CAPSULE SENSOR OPU872CP PIN CONFIGURATION OPU872CP 19.5 0.8 3.5 2 2 8 7 2 5.5 2 30 (Unit: mm) P1 8.6 P4 0.8 4 2 LED phototransistor 0.5 * Pin Connection Diagram 4.4 2.6 P1 P2 P3 P4 P1 P2 P3 P4 Cathode Collector Emitter Anode 2/9 CAPSULE SENSOR OPU872CP OPTICAL LAYOUT Prism Optical path LED Aspherical lens Light shielding plate Phototransistor Case Connector Back cover 3/9 CAPSULE SENSOR OPU872CP ABSOLUTE MAXIMUM RATINGS Parameter Forward Current Pulse Forward Current Light Emitter Reverse Voltage Power Dissipation Forward Current Derating Factor Collector-emitter Voltage Photosensor Collector Current Collector Power Dissipation Emitter-collector Voltage Operating Temperature Storage Temperature Symbol Test Condition Rating IF IFM VR PD -- VCEO IC PC VECO Topr Tstg -- -- Ta=25C Ta25C Ta=25C 60 0.5 6 120 1.7 20 10 150 5 -10 to +60 -10 to +60 Unit mA A V mW mA/C V mA mW V C C Note -- tw=100ms T=10ms -- -- -- -- -- -- -- -- -- ELECTRICAL CHARACTERISTICS Parameter Forward Voltage Light Emitter Reverse Current Peak-emission Wavelength Photosensor Leakage Current Collector-emitter Voltage Dark Current *1 *3 *1 *2 Symbol Test Condition Min.
