Vishay launches outdoor infrared sensor module with extended temperature range

Pennsylvania, MALVERN — April 26, 2021 — A few days ago, Vishay Intertechnology, Inc. (NYSE stock code: VSH) announced that its Heimdall packaged TSSP77038 infrared (IR) sensor module has added an extended temperature “E” option device—TSSP77038ETR . The storage temperature of Vishay Semiconductors TSSP77038ETR is extended to -40 °C to +110 °C, and the operating temperature is extended to -30 °C to +85 °C, specifically to meet the special requirements of outdoor applications.

The storage temperature and working temperature of the standard packaged infrared sensor module are only -25 °C~+85 °C. The TSSP77038ETR adopts a robust Heimdall package design that can work in a wider temperature range and is suitable for applications with direct sunlight and large temperature changes, including garage door grating systems, door locks, and packaging and trash can sensors.

Used in conjunction with Vishay’s TSAL6200 infrared emitting tube, the detection distance of TSSP77038ETR is up to 8 m at a forward current of 50 mA. The device is suitable for detecting the distance of objects, and can be used for toys, remote-controlled airplanes and robots. It can also be used as a reflective sensor for hand dryers, towels or soap boxes, automatic faucets, toilets, vending machines, falling objects detection, and safety gates and pet exits. getting Started.

The sensor module can receive infrared pulses from the transmitter with a peak wavelength of 940 nm. The operating voltage is 2.5 V to 5.5 V, and the power supply current is as low as 0.7 mA. It is sensitive to the 38 kHz carrier frequency. The device is insensitive to power supply voltage ripple noise, can shield EMI, and the daylight filter can suppress visible light. The sensor module complies with RoHS and Vishay green standards and is halogen-free.

TSSP77038ETR can now provide samples and has achieved mass production. The lead time is 8 weeks.
