Security/Detection
If your design challenge is to create the best motion sensor or motion detector - fire sensor or fire detector, smoke sensor or smoke detector - you've come to the right company. Dexter's sensor technologies are at multiple fronts today, reducing the threat of combat on land, sea and air. Yet the industry leading advantages of Dexter sensors - low cost, high sensitivity, low energy consumption and long life - make them the perfect motion sensor for home, office and facility applications. Dexter thin-film and silicon detectors can target precise threats, whether defined by movement, temperature or body mass. Intensive MIL-STD-883H testing performed by Trialon Corporation, an independent testing facility, confirm that Dexter Research's silicon-based temperature sensor detectors meet the same rugged requirements of 1,000G's for mechanical shock and 30G's in random vibration for which our thin-film detectors are famous.

Services
By working in this way to help meet our customers’ needs, we have developed more than 30 models and over 900 finished goods. That gives you more detector choices, by far, than you will find from any other supplier. These provide the core products we customize for our customers. There’s no “one size fits all” here. With Dexter detectors, you will not need to compromise on noise, sensitivity, size, and durability. Instead, we have just the right component to help optimize performance for your sensing application.
