The enhanced TSSP77038 sensor module from Vishay Intertechnology in the Heimdall package offers a storage temperature range of -40 °C to +110 °C and an operating temperature range of -30 °C to +85 °C. When used with Vishay’s TSAL6200 IR emitting diode at a forward current of 50 mA, this sensor module delivers long-range presence sensing up to 8 m.


Designed to meet the special requirements of the outdoor application, this new infrared sensor module in standard packages offers limited storage. This new sensor can handle a wider temperature range, making it ideal for operation in applications exposed to direct sunlight and large temperature variations, including garage door light barrier systems, door locks, and sensors for the package, trash bins, etc.


It is suitable to be used for sensing the distance to objects for toys, drones, and robots, and may also be used as a reflective sensor for hand dryers, towel or soap dispensers, water faucets, toilets, vending machine fall detectors, and security and pet gates.


With a peak wavelength of 940 nm, the sensor module operates at a supply voltage range from 2.5 V to 5.5 V and features a low supply current of 0.7 mA. Besides, it is sensitive to a carrier frequency of 38 kHz. The device is insensitive to supply voltage ripple noise and provides shielding against EMI, while a daylight blocking filter suppresses visible light. The sensor module is RoHS-compliant, halogen-free, and Vishay Green. The samples and production quantities of the TSSP77038ETR sensor module are available, with lead times of eight weeks.
