Precision Hermetic Technology (PHT)
PHT - Circular Connectors
Our housings are fabricated using a one-piece shell construction for ultimate strength and performance. Polarizing keys, bayonets and other hardware are machined in, providing a more robust product with long-term reliability. We offer matched and compression sealing for standard as well as custom products.
