Remote control for set-top boxes in Egypt market, with excellent quality, excellent price and high cost performance

A variety of models are available, silicone case can be added, there are high quality, general quality level for selection

Performance description:

1, effective distance and directivity test:
when testing within the valid distance, the provided receiver is used, and no irregular operation behavior is allowed.
   1.1 offset angleΘ = 5 °(Up, down, left, right) effective emission distance≥ 8.0m.
   1.2 horizontal offset angleΘ = 45 °(Left, right) emission effective distance≥ 6.0m.

    1.3 vertical offset angleΘ = 30 °(Up, down).

2. Peak infrared irradiance of remote control:
in natural light or fluorescent lamp200±50lx under ambient illumination, the power supply voltage used by remote control is rated operating voltage, and the remote control launching site

horizontal luminance meter distance from peak perpendicular shaft light receiving point0.5m press each button of remote control, and the peak irradiance of infrared light emitted should not be less40uW/c㎡
     2.1 directivity (working voltage3.0V):
the peak irradiance of red emitted by remote control is20uW/c㎡, the cone angle with remote control launching site as the vertex should not be less30 °.
     2.2 directivity of remote control under undervoltage (operating voltage2.25V):
the infrared peak irradiance of the remote control is10uW/c㎡, the cone angle with remote control launching site as the vertex is not less30 °.

3, environmental test:
     3.1 high temperature storage test:
the remote control temperature is55℃ in the environment, shelve2H after that, restore2H, should meet the requirements, work without abnormal phenomenon.
     3.2 constant damp heat test:
the remote control temperature is40℃, the relative humidity is93% in the environment, shelve96H after, Sutra4H recover, everything should be normal.
     3.3 low temperature storage test:
the remote control temperature is-25℃ environment, shelve2H after that, restore2H, everything should be normal.
     3.4 temperature change test
the remote control should be able to withstand the temperature cycle change test shown in the following figure.6 after the cycle test, everything should be normal.

4, free drop test
remote control without packaging under the condition of battery installation, from80Cm height, free falling at no less3Cm thick wood texture board.

During the test, according to the specified test surface shown in the figure, according... Drop in sequence and cycle three times.

After the test, the remote control should have no cracks, the battery cover should not fall off, and all button functions should be normal.

5, waveform

6, scanning vibration test

the remote control shall be able to withstand the vibration test specified in the following table. After the test, the remote control shall be normal.
