TSSP4056 Fast Proximity Sensor

tssp4056New infrared (IR) sensor designed to provide fast, low-cost proximity sensing in a variety of systems. The Vishay Semiconductors TSSP4056 is the industry’s first fixed-gain sensor containing a band-pass filter tuned to 56 kHz to feature a monotonic sensitivity vs. frequency response curve from 30 kHz to 54 kHz. The device detects modulated pulses from a separate IR emitter with a high sensitivity of 0.4 mW/m2, while fast readings in under 5 ms are possible using successive approximation techniques as demonstrated in Vishay’s Fast Proximity Sensor software.

TSSP4056 Feature List

  • > 4x dynamic range from lowest to highest sensitivity
