PreView Sentry 79GHz Front & Rear Detection Radar Solution
Sensata’s PreView Sentry®79 is an advanced 79 GHz front and rear detection radar sensor designed to enhance driver awareness and minimise the risk of blind spot related accidents. The sensor has a fully configurable detection zone, with the ability to detect objects at ranges up to 40 meters (131 feet). The width of the detection zone is adjustable to fit almost any vehicle type to keep operators and job sites safer. With its high-precision radar technology, the PreView Sentry®79 provides drivers with real-time, reliable information about objects in their blind spots, significantly reducing the potential for collisions during take-off and backing manoeuvres. It is the industry’s most flexible, accurate, and powerful active blind spot monitoring solution available.

The expansion of Sensata’s PreView® Radar product line is the result of over two decades of experience working with drivers, fleets, body builders, and OEMs to understand and deliver on requirements and preferences for radar-based collision mitigation solutions.
