Introduction
Product Overview
Amphenol 97 Series Connectors are UL and CSA recognized. The PT Series Miniature Cylindrical Connectors, including MIL-DTL-26482 Series 1 compliant models, are designed for general duty and environmental applications in industrial and military markets. These connectors offer high reliability, design flexibility, and environmental sealing through grommet and clamp designs. They feature a wide operating temperature range of 55C to +125C and an operating voltage of up to 1000 VAC (RMS) at sea level. Contacts are machined from low-loss copper alloy and gold-plated for corrosion resistance and extended shelf life. Resilient inserts provide high dielectric strength and a moisture barrier. Various shell finishes and back-end accessories are available.
