Descriptions

The device is a miniature SMD type infrared remote control system receiver that has been developed and

designed by utilizing the most updated IC technology. The PIN diode and preamplifier are assembled on PCB, the epoxy package is designed as an IR filter. The demodulated output signal can directly be decoded by a microprocessor.

Applications

1. Optical switch

2. Light detecting portion of remote control

AV instruments such as Audio, TV, VCR, CD, MD, etc. Home appliances such as Air-conditioner, Fan , etc. The other equipments with wireless remote control. CATV set top boxes Multi-media Equipment

The Notice of Application:

Transmission remote control signal consist of four parts: Encode Part, IR Transmitter Source, IRM device, Decode Part

1. When IRM-H2xxT code select frequency, it need to well understand the center system of encode part.

2. Strong or weak light of IR Transmitter can affect distance of transmission. 3. Minimum Burst Length Tburst (number of pulses per burst) : 10 cycles

4. It needs to ensure the translation range of decode part if it is applied to the pulse-width range.

If the above items hardly assure of its application, it’ll cause NG(no good) message from the edge of signal.

Note: This model might not work well with RCA code.

Test Method：

The specified electro-optical characteristics is satisfied under the following Conditions at the controllable distance. cMeasurement place

A place that is nothing of extreme light reflected in the room. dExternal light

Project the light of ordinary white fluorescent lamps which are not high Frequency lamps and must be less then 10 Lux at the module surface. (Ee≦10Lux)

eStandard transmitter

A transmitter whose output is so adjusted as to Vo=400mVp-p and the output

Recommended method of storage

Dry box storage is recommended as soon as the aluminum bag has been opened prevent moisture absorption. The following conditions should be observed, if dry boxes are not available:

Storage temperature 10℃ to 30℃ Storage humidity ≦60%RH max.

After more than 72 hours under these conditions moisture content will be too high for Reflow soldering:

In case of moisture absorption, the devices will recover to former condition by drying under the following condition:

192 hours at 40℃+5℃/-0℃ and 5%RH (dry air / nitrogen) or 96 hours at 60℃+5℃ and < 5%RH for all device containers or 24 hours at 125℃+5℃ not suitable for reel or tubes. …… 此处隐藏：3905字，全部文档内容请下载后查看。喜欢就下载吧 ……
