TSSP93038DF1PZA and TSSP93038SS1ZA IR Sensor Modules

Vishay's fixed-gain infrared (IR) sensor modules are designed to lower costs and increase stability for outdoor sensor applications. Offering typical irradiance of 1.3 mW/m² in compact Minimold packages, the surface-mount TSSP93038DF1PZA and leaded TSSP93038SS1ZA provide robust operation in direct sunlight while still providing enough sensitivity for light barrier applications. Unlike high-sensitivity fixed-gain IR sensor modules that require attenuators like dark panels, apertures, and sunshades to protect them against sunlight (adding to overall solutions costs), the controlled sensitivity of the TSSP93038DF1PZA and TSSP93038SS1ZA allows them to operate in full sunlight without unwanted pulses. For short-range presence and proximity applications, the sensors’ reduced sensitivity eliminates the need for extremely low emitter forward currents which can lead to unstable intensity outputs. The devices are designed to receive IR pulses from an emitter with a peak wavelength of 940 nm.
