IR sensor module has wide temperature range of outdoor use

Designed to meet the requirements of outdoor applications, the Vishay Semiconductors TSSP77038ETR now has a storage temperature range of -40 to +110 degrees C and an operating temperature range of -30 to +85 degrees C.

The extended temperature “E” option for the infra red (IR) sensor module is available from Vishay in the Heimdall package. Standard packages for IR sensor modules offer limited storage and operating temperature ranges of -25 to +85 degrees C. The robust design of the Heimdall package however enables the TSSP77038ETR to handle a wider temperature range. It can operate in applications exposed to direct sunlight and large temperature variations, including garage door light barrier systems, door locks, and sensors for package and refuse bins.

The TSSP77038ETR delivers long range presence sensing up to eight metres when used with Vishay’s TSAL6200 IR emitting diode at a forward current of 50mA. The sensor module can be used to sense the distance to objects for toys, drones, and robots, and it may also be used as a reflective sensor for hand dryers, towel or soap dispensers, in public bathrooms, vending machine fall detectors or security and pet gates.

Designed to receive IR pulses from an emitter with a peak wavelength of 940nm, the sensor module operates at a supply voltage range from 2.5 to 5.5V. It features a low supply current of 0.7mA, and is sensitive to a carrier frequency of 38kHz. According to Vishay it 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.

Samples and production quantities of the TSSP77038ETR are available now, with lead times of eight weeks.

Vishay manufactures one of the world’s largest portfolios of discrete semiconductors and passive electronic components for the automotive, industrial, computing, consumer, telecommunications, military, aerospace, and medical markets.
