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.

Security/Detection
ST60 Dual
A two-channel silicon-based thermopile detector in a TO-5 package. Each small active area size is 0.61mm x 0.61mm. This is our lowest-cost and fastest time constant two-channel detector. It delivers a time constant of 18ms with Nitrogen encapsulation gas combined with a very low Temperature Coefficient of Responsivity of -0.04%/°C. This detector has a very short thermal shock response to ambient temperature change.

Digital Solutions
Dexter's Digital Detectors and Temperature Sensor Modules (TSM's) are based on Dexter's superior silicon thermopile technology and incorporate an ASIC that provides a cost effective front end for reading out the detector output. The digital solutions include pre-amplification, A/D, multi-plexing and SMBus communications. Additionaly, the SMBus can accommodate communications with up to 100 digital products. Our digital solutions are housed in industry standard TO-5/TO-39 packages.
