Vishay is the world’s leading supplier of infrared (IR) receivers. No other supplier offers a similar breadth of products, holders, application and technical support, and overall knowledge of infrared communication. Our customers have confidence that our IR receivers will receive remote control signals while filtering out noise in the most demanding ambient environments. Vishay’s IR receivers are used for remote control and for transmisive and reflective sensors.

Info

Remote Control:

No single automatic gain control (AGC) algorithm can completely suppress all noise and pass data signals. Vishay has developed five different AGC response algorithms based on coding schemes and ambient noise conditions. These AGC algorithms allow developers to choose the most appropriate receiver for their application and coding scheme.

Presence of an Object:

To avoid over or under detection due to varying ambient light levels, Vishay’s TSSP4038, TSSP58038, TSSP6038, and TSSP57038 have a fixed gain. Once the design of the optical parameters such as the intensity of the emitter, the aperture in front of the receiver, and the alignment of emitter and detector are determined, the sensor will have stable, repeatable performance under all lighting conditions. The output of the sensor is the demodulated signal of the emitter, typically 38 kHz modulated bursts.

Proximity of an Object:

Many applications require a reflective sensor that detects not only the presence of an object, but also its relative proximity. This information can answer the question whether an object is moving toward or away from the sensor. This is possible with Vishay’s TSSP4P38, TSSP58P38, TSSP6P38, TSSP77P38 and TSSP57P38 IR proximity sensors. The response to a long reflected burst signal is an output pulse, whose width is inversely proportional to the distance of the object from the sensor.
