Sheet No.: D3-A05001EN 6 GP2A28AJ000F/GP2A28CJ000F ■ Design Considerations ● Design guide 1) This product operates the light emitter by pulse drive. Please supply the stable supply voltage in order to prevent error operation by pulse current. Please use this device after connecting a capacitor between VO and GND for prevention of line noise. 2) Prevention of detection error Please be careful that you need to keep the direct inverter light away from the photo detecting surface since the device will not operate correctly in such case. In addition, we recommend to make sure the operation test in the actual application. 3) Plugging in/out The connector should be plugged in/out at normal temperature. This product is not designed against irradiation and incorporates non-coherent IRED. ● Recommended Installation Hole drawing 8-R0.1 4.2 22.1±0.1 4.2 8.5 1 Sheet No.: D3-A05001EN 7 GP2A28AJ000F/GP2A28CJ000F ● Parts This product is assembled using the below parts. • Photodetector (qty. : 1) [Using a silicon photodiode as light detecting portion, and a bipolar IC as signal processing circuit] Category Photodiode Maximum Sensitivity wavelength (nm) 900 Sensitivity wavelength (nm) 700 to 1 200 Response time (μs) 400 • Photo emitter (qty. : 1) Category Infrared emitting diode (non-coherent) Material Gallium arsenide (GaAs) Maximum light emitting wavelength (nm) 950 I/O Frequency (MHz) 0.3 • Material Case Black polyphernylene Sulfide resin (UL94 V-0) Lens Acryl resin (UL94 HB) Bottom cover Polycarbonate resin (Black) (UL94 V-2) • Others Laser generator is not used.
