GP1UD26XK Series/GP1UD27XK Series/GP1UD28XK Series/GP1UD28YK Series (cid:2) Precautions for Operation 1. When this infrared remote control detecting unit shall be adopted for wireless remote control, please use it with the signal format of transmitter, which total duty ratio D (Emitting time Σn t / Transmitting time for 1 block T) is 40% or less. ON signal time T t N=1N ON (Pulse width of the presence of modulated IR) should be 250µs or more. In case that the signal format of total duty and ON signal time is out of above conditions, there is a case that reception distance is much reduced or output is not appeared. Transmitting time for 1 block:T TON t1 t2 t3 tn n Dt=( Σ tN / T)×100 (%) N=1 2. Use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating conditions of light emitting device and the characteristics of the light detecting unit. 3. Pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse. Care must be taken not to touch the light detector surface. If it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. In case some solvents are required, use methyl alcohol, ethyl alcohol or isopropyl alcohol only. Also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of the function, fading of markings such as the part number. 4. The shield case should be grounded on PCB pattern. (The area across the shield case and the GND terminal is internally conductive in some cases and non-conductive in some other cases.) 5. Do not apply unnecessary force to the terminal and the case. 6. Do not push the light detector surface (photodiode) from outside. 7. To avoid the electrostatic breakdown of IC, handle the unit under the condition of grounding with human body, soldering iron, etc. 8. Do not use hole and groove set in the case of the light detecting unit for other purposes, since they are required to maintain the specified performance. 9. External Circuit Examples (Mount the outer parts as near the unit as possible). GND GND CO+ R1 VCC Ve (Circuit parameters) VOUT VO R1=47Ω±5% C1=47µF In setting R and C, use suitable values after considering under the real condition 1 1 10. There is a possibility that noise on output may be caused by environmental condition (Disturbing light noise, Electromagnetic noise, Power supply line noise, etc.) even if there is no input transmission signal. 11. Please shall confirm operation or your actual machine. Because the output pulse width of this product is fluctuated by environmental conditions such as signal format, temperature, distance from transmitter, and so on.
