IrDA transceivers for remote control
- The IrDA transceivers emitter can be used to transmit remote control signals
- This eliminates the need to design-in an additional, discrete LED emitter
- Vishay's IrDA transceivers have the best, overall performance

Window size in housings
- Once a Vishay transceiver is chosen, the next step is to design the window for peak performance. Improper designs will severely reduce transmit distance and angles
- The optical window must be a minimum size of d1 x d2, rectangle or ellipse. Click ‘More info’ for sample calculations
- Recommendations for best IR plastics are included
