What is this ....

Hi guys,
can anybody give me some info regarding the pic? well, the one in the right is an IR LED and there is also a ceramic capacitor but can anyone give me some info regarding the IR Receiver in the left with a black patch on its rectangular body?
thanks,
Surya

Its and 38KHz IR receiver either from Siemens or Vishay Telefunken.
The model seems to be more like Siemens SFH505/SFH506.
Here's the datasheet

Also possible: this is a homebrew IrDa device or only receiver and trnsmitter.(another side of PCB invisible)

Or it may be an IR Proximity Detector.

well thank u for the info. It is from SHARP but i was not successful in getting its datasheet. Its product number GP1U26R series. can anybody give me a link to get some info?
Thanks,
Surya

once anyone aon of u get some info can anybody tell me why is there a capacitor in the circuit?

The capacitor seems to be for power supply decoupling. But I am not sure since I don't know where it is connected. Do you have the circuit diagram with you?

Chances are that yes it is decoupling. When a capacitor is placed that close to the pins.
I'm looking at the datasheet for a PNA4602M (an infrared detector module) and that has....
if you were counting the pins left to right signal out, Gnd and Vcc. This is not the same part but the placement of the capacitor would suggest it is possibly close in function and pin out. The sharp datasheet says it may need a capacitor depending on the operating enviroment
